Dark Chocolate Zucchini Brownies

So moist, rich, and chocolaty that no one will guess they have veggies, 100% whole grain, and no eggs. Easy to adapt for vegan, gluten- and dairy-free.

Veggies in chocolate form? I'm all over it! With home gardens and farmer's markets overflowing with zucchini, this is a great time to make a batch of these zucchini brownies. They are amazingly rich and moist and will particularly satisfy those chocolate lovers out there.

I knew zucchini brownies were meant to be when King-Man came home from work with a GIGANTIC homegrown zucchini brought to him by our friend, Terry.  We're wondering if Terry's husband, Robert, has been feeding their zucchini steroids. This thing was seriously huge--one zucchini was big enough for two batches of these brownies. So, I made a batch to enjoy now and a second batch to freeze for later. (Yes, you can freeze these brownies!)

Healthified!
I looked around for a healthy zucchini brownie recipe, but couldn't find one that wasn't also loaded with a lot of unhealthy ingredients--pretty  much negating the whole zucchini-makes-them-healthy concept.  After some experimenting, I came up with a recipe that had as many healthy ingredients as possible while still tasting like a decadent dessert. My zucchini brownies aren't exactly health food, but except for the sugar my ingredients are all good for you in reasonable quantities. I guess I'd call my recipe healthiER. Here's how I healthified the ingredients:

  • reduced the amount of sugar
  • reduced the amount of oil 
  • used coconut oil (for it's health benefits and flavor); you can use canola or veg. oil, too
  • added yogurt (replaced some oil and adds moisture and nutrients)
  • used 100% whole grain flour (no white stuff at all)
  • omitted eggs entirely (not that they're bad for you, but they're unecessary)
  • used dark cocoa powder (higher in antioxidants), although you can use regular cocoa, too

Vegan, Gluten- & Dairy-Free options. Easy substitutions are listed in my recipe for these dietary preferences.

You can't taste the zucchini. If you're offering these brownies to people who are likely to turn up their nose at the thought of zucchini in brownies, my advice is: don't tell them & they'll never know. Seriously. The pureed zucchini disappears into the batter as it cooks. It provides moisture and some nutrition without a veggie flavor--just like the carrots in carrot cake.

Step-by-step photos for making
Zucchini Brownies 

Step 1. Assemble the ingredients: 

  • zucchini -- cut it up so it can be measured (2 cups per batch)
  • unsweetened cocoa powder -- I prefer the dark, but regular cocoa is good, too
  • oil -- I used coconut oil, but you can use canola or vegetable oil or even melted butter
  • yogurt -- regular or Greek (omit this and use more oil for a dairy-free version)
  • whole wheat pastry flour -- you can also use gluten-free oat flour
  • sugar -- I haven't tried these with alternative sweeteners. Feel free to try substitutions, but I can't guarantee the results.
  • vanilla extract
  • baking powder
  • kosher salt

Step 2. In a blender or food processor, puree the zucchini, yogurt, oil, vanilla, and sugar. This releases the moisture inside the zucchini and the pureed mixture disappears into the batter. Other zucchini brownie recipes call for grating the zucchini, but that results in a dryer batter and bits of visible zucchini in the finished brownies. Pureeing these ingredients is an important step for producing a good brownie texture and appearance.

Step 3. Add the remaining dry ingredients to a large bowl and whisk them together. (The batch pictured below uses regular cocoa powder. I'll show you a batch using dark cocoa later.)
Step 4. Add the pureed mixture to the dry ingredients and stir just until it's evenly moistened throughout. 
Step 5. Pour the brownie batter into a greased/oiled 9x13 pan and bake for 20-25 minutes. 
Step 6. Move to a cooling rack.

Unfrosted Brownies. You don't have to frost these brownies. If you choose not to, I recommend dusting the top of the cooled brownies with powdered sugar to improve their appearance.

Frosted Brownies (highly recommended!)
I use my One-Minute Chocolate Frosting. One frosting batch is just enough for a thin, tasty layer of frosting. I let the brownies cool 20-30 minutes before frosting them--they're still slightly warm but not hot. You can sprinkle nuts on top, if you like. I usually add nuts to half of the pan to accomodate different preferences. For ingredients, photos, and instructions for making the frosting:

A batch using dark cocoa powder (highly recommended!)
I used Hershey's Special Dark Cocoa Powder for my second batch so that I could do a taste comparison. These were hands-down my favorite--moist, rich, and much more chocolaty. But I'm a big chocolate lover. The more chocolaty, the better! Plus, these have the added bonus of more antioxidants from the dark cocoa. You can see the darker batter in the photos below.The regular cocoa powder used in my first batch results in a milder chocolate flavor, if that's what you prefer.

Cut and serve!

Or, cover them and save for later. I think the flavor improves the next day. You can also cover and freeze them. Might as well make a couple of batches while you're at it!

I like using these shallow pans that come with lids. It's easy to cut and remove the brownies from these, and they're great for stacking and storing compactly. Regular 9x13 baking pans work fine, too, if that's what you have.

You can see how moist and chocolaty these are. They really do taste amazing. Honestly, no one would ever know they've been healthified.

Zucchini Brownies
By Monica              Servings: 24 servings
Ingredients
  • 2 cups chopped raw zucchini
  • 1/4 cup coconut or vegetable oil, or melted butter
  • 1/2 cup low fat yogurt* (regular or Greek)
  • 1-1/4 cups sugar
  • 1 tablespoon vanilla extract
  • 2 cups whole wheat pastry flour (may substitute gluten-free oat flour, if desired)
  • 1/2 cup unsweetened cocoa powder (dark cocoa recommended)
  • 1-1/2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • FROSTING INGREDIENTS:
  • 1 cup semisweet or bittersweet chocolate chips
  • 1/4 cup canned evaporated milk (may substitute almond milk, if desired)
  • 2 tablespoons butter (may substitute coconut or vegetable oil, if desired)
  • 1/2 teaspoon vanilla
  • 1 cup powdered sugar
  • 1/2 cup chopped pecans or walnuts (optional)
Directions
Preheat oven to 350 degrees and grease a 9x13 pan. In blender or food processor, puree zucchini, oil, yogurt, sugar, and vanilla. Set aside. In large bowl, whisk together flour, cocoa, baking powder and salt. Add pureed wet ingredients to dry ingredients and stir until moist throughout. Pour into greased pan, spread evenly, and bake for 20-25 minutes until toothpick comes out clean or with a few moist crumbs. (Overcooking will result in dry brownies.) Remove from oven and place on cooling rack. Cool for 20-25 minutes and frost while still warm.

TO MAKE FROSTING:
(View photos & tips for making frosting at www.TheYummyLife.com/Chocolate_Frosting) Combine chocolate chips, evaporated milk, butter (or oil) and vanilla in microwave-proof bowl. Microwave on full power for 30-40 seconds. Remove and whisk until chocolate chips melt in and mixture is smooth (return to microwave for a few seconds if necessary). Add powdered sugar and continue whisking until smooth. Spread evenly over brownies while they are still slightly warm. Sprinkle with chopped nuts, if desired.

Brownies may left unfrosted, if preferred. Dust the top lightly with powdered sugar for a prettier appearance.

Brownies (frosted or unfrosted) may be covered and frozen. Remove cover as they thaw to prevent condensation from forming and making the frosting soggy.

Nutritional Information for 1 serving (without nuts, cut into 24 servings per batch )
Unfrosted: 103 calories, 2.8g fat, 19.7g carbs, 2g fiber, 2g protein; Weight Watchers PtsPlus: 3
Frosted: 181 calories, 6.9g fat, 30.9g carbs, 3g fiber, 2.2g protein; Weight Watchers PtsPlus: 5

*To make dairy-free/vegan, omit yogurt and increase oil from 1/4 to 1/2 cup.

My father-in-law keeps handing us giant zucchinis that I can't think of enough things to use them up in.  I'm getting burnt out on zucchini bread (and my freezer's filling up with it!)- I'll definitely be trying this recipe out!  My husband might even eat it if he doesn't know it is "healthy."  Thanks!

Love your site!  I was just given 2 large zukes by a coworker, so perfect timing on this recipe. Should these be frozen unfrosted?  Looking to take them to the beach and want to make ahead.  Thanks!

Monica says:
Hi Jennifer. You can freeze them frosted. Works great. Remove the lid while they're thawing so condensation doesn't form and make the frosting soggy. Once they're thawed, the lid can be put back on. I froze a batch of frosted ones that we thawed and started eating yesterday. They're still tasting great today. Hope you enjoy them at the beach!

I am definitely trying these.

I made my husband some juice with celery, kale, cucumbers, ginger and green apples last night. I saved the pulp and today I found me some zucchini muffin recipe online and instead of adding the zucchini I added the green pulp. The result was amazingly yummy. there was none left to tell the story. Even the kids who "hate" green stuff gobbled them down. :)

I will try your recipe with my green pulp next time. TFS! :)

Hi Tereza. Your green pulp sounds so nutritious! It should work great in these brownies. Go for it!

I'm a LONG time reader and first time commenter. And a big fan of everything on this amazing blog. I follow a lot of health blogs with overnight oats but always shied away. Cold oats? No thanks. But then I saw your new flavors and had to try the mocha one... OH MY WORD!!! Tasted like dessert! I couldn't stop eating it but had enough self control to leave some for breakfast the next day. The only thing i added in besides was some chopped up chocolate- good call :)
Now I'm excited to make these for my gluten and dairy free siblings! Thanks so much for these awesome recipes.
p.s.-  wrote this while eating your raspberry vanilla flavor. I've been doing a new flavor every day! YUM!!!

Betty says:
Mine do not look like this at all.  Maybe because of not being able to find the dark chocolate cocoa powder?  They taste ok with frosting, but without, I think a little dry and not near chocolately enough.  Next time I will definitely try to find the dark chocolate.  I don't think I over baked them, but they don't look gooey rich like yours.  I wonder what I did wrong besides the lighter cocoa???
Reply Posted 11 months ago
Monica says:
Hi Betty. I'm sorry to hear your brownies were disappointing. I do recommend the dark chocolate version, since your looking for a more chocolaty flavor. Even the texture is better, for some reason. My photos of the cut brownies stacked on a plate are the dark cocoa version, so I'm guessing that's why yours don't look like mine. The grocery stores around here carry the dark cocoa powder that I used; I hope you're able to find some where you are. I think that will most likely solve your problem. If you can't find the dark cocoa, you might try stirring in 1/2 cup of dark chocolate chips or cut up dark chocolate bars. That might help. Hope you have better results next time. :-)

Zucchini are in season, but why are they more than bananas?  This recipe is in the oven with 4 bananas and a 12 oz block of silken light tofu, hold the yogurt!  Can't wait 20 more minutes!

dolly says:
So they are extremely dense.  I didn't get around to frosting them, don't have the proper vegan supplies for that and really wanted to eat one!  Next time I'd add chocolate chips and/or nuts to the batter and would make again with bananas or try with zucchini should I happen across some at the right price. GREAT recipe!

Do you think I just use Bob's Red Mill all purpose gluten free flour cup for cup instead of oat flour?  What about substituting applesauce ?
Reply Posted 11 months ago
Monica says:
Hi Jena. Yes, substitute the flour cup for cup. Not sure if you're wanting to substitute applesauce for the yogurt, oil or both. I've used applesauce in other recipes to replace part of the oil, but haven't tried it in this recipe. It would take some experimenting to figure our the right amounts, so I can't give you specific advice on that.

This recipe looks delish. I like to live by the philosophy of "use what you have". I don't have whole wheat flour, wondering if the reg white stuff will work. Also, I dont want to make a big batch because there are only 2 ppl in my family. If I cut recipe in 1/2 will it turn out the same?

Thank You in Advance!

Thank you so much for this recipe! My daughter loves chocolate but hates veggies. I managed to get black beans in her with the Meal Makeover Moms brownie recipe - that turns out like a flourless brownie. Now, thanks to your recipe, I've gotten zucchini in her! Your recipe turns out like a cake brownie so now I have the 2 standard types of brownies in my healthy cooking arsenal. (It's like a weird food war in my house....)

I made these last weekend and they were a hit! I was wondering if butternut squash puree might work - I have some in the freezer that really needs to be used. What do you think?
Reply Posted 10 months ago
Monica says:
Hi Rachel. I think the butternut squash should work in this recipe. I can't say for sure, since I haven't tried it. But, if I had some in my freezer like you, I'd give it a try. As long as the water content of the squashes is similar, I don't see why it wouldn't work.
Reply Posted 10 months ago
Rachel says:
Thanks for the reply, Monica. I think the texture came out a bit better, but I did have to use some milk to give the batter some more moisture. I do think I let them bake a little too long, but I've only had edge pieces so far. I'll have to test them on my fiance when he comes home from his business trip!

Hi Monica. I just made your banana oat bread yesterday and it was delicious! I thought I would try out this zucchini brownie recipe next, but I don't own a blender or food processor.

Jenny says:
hand *mixer
Reply Posted 10 months ago
Monica says:
Hi Jenny. You can shred the zucchini with a grater instead of pureeing it. Although the brownies should still have good texture and taste once they're baked, the batter will be much thicker because the water in the zucchini doesn't get released from being blended. That will happen during baking though. Also, there may be visible bits of zucchini in the brownies--not a bad thing, just different from the pureed zucchini version.

Would you consider eating one brownie as 1 serving of vegetables? I realize it might be pushing it, but my work is doing a 5-a-day challenge and I'd like my day to bring a veggie to be fun and unexpected like zucchini brownies! What do you think? Thanks for the recipe! I can't wait to try it!
Reply Posted 10 months ago

Hi Lindsay. Hmmm. The entire recipe has 2 cups of zucchini, and that is divided over 24 brownies. If you consider 1/2 zucchini to be a serving of vegetables, you would have to eat 6 brownies to get a full serving of zucchini.

Hi Sindee. If you can find white whole wheat flour, that is very similar to whole wheat pastry flour. If not, you can use an equal amount of regular all-purpose flour. I think oat flour would work well, too.

This is a great idea but I wouldn't all the end result brownies, nor did they look anything like the photo. I am glad I added nuts and chocolate chips to them to hide the rest. The taste of flour is prevalent, They tasted more like an undercooked floury cake. Definitely not chocolaty enough for a brownie. I had high hopes, but I will be saving my zucchini for zucchini bread and roast Summer vegetables recipes. Have another recipe for brownies made with spinach and carrots, which, although also more cake like than traditional, comes out a lot better and healthy too.

These are amazing! I made them for my dorm last night and the entire pan was empty within an hour...they didn't even last a night! Everyone was very surprised to hear that there was zucchini in them...you REALLY can't taste it at all! And they come out so rich, moist, and decadent! YUM! Thank you!

Yay, Kendra! I'm so happy to hear these brownies are "dorm-approved." Impressive that you bake in your dorm. I want to go back to college and room by you! :-)

Just made these tonight...tired of zucchini muffins needed something new to use up the zucchini.  These were a hit with the family and I think the best part is that the zucchini is pureed.  I did substitute the sugar with sucanat and I didn't have any yogurt so I used all coconut oil instead and they turned out fabulous.  Thanks for the great recipe.

Hi Melanie. Your substitutions sound great. This recipe is turning out to be pretty flexible. It's really helpful to hear about the successful changes you made. Thank you! :-)

Can I use whole wheat flour...not pastry flour?
Reply Posted 10 months ago
Monica says:
Hi Melissa. I haven't tried these with regular whole wheat flour, but my guess is that it would work fine. The texture may be a little heavier, but I would expect the taste to be good.

Greetings from Northern Illinois! Love, love, love your recipe!! Thanks so much for sharing it :)  Instead of frosting, I often just sprinkle the batter with chocolate chips and chopped pecans before baking. This is tastes awesome when I don't feel like frosting.

i found this on pinterest the other day, and i've just made two trays of them. oh my absolute giddy aunt... they are uh-maaazing. i had to 'make my own' wholewheat flour cause i didn't have any - so i added a bit more than half a cup of wheat bran to plain flour to make up the 2 cups, and i also added a handful of dessicated coconut. uh-maaazing. uh-maaaaaaaaaazing. you are my brownie hero. that is all. xxx

I started making these today and realized halfway in that I didn't have enough dark cocoa powder. Bummer. I substituted Dutch process cocoa powder and added extra but they still were lacking in chocolate flavor for this chocoholic. But the texture was great! I guess that just means I'll need to give it another go :)

Monica says:
Hi Molly. Don't you hate it when that happens? It's especially a bummer when you're so far into a recipe before you realize you're short on ingredients--no turning back at the point. I hope your next batch is more chocolatey for you. That dark cocoa powder really does make a difference.

Hi,
I made these last night they were soo yummy but I was just wondering if anyone else has found that they are very dense when making them with Gluten Free flour? Should I have used Self Raising Gluten Free flour? Or could it have been the amount of zucchini I used how much is 2 cups of Zucchini!!
They were still a hit and I cant wait to make them again!!
Thanx

Monica says:
Hi Bec. I haven't tried these with gluten free flour, so I can't weigh in on that. To measure the zucchini, I first chopped it into approx. 1/2" cubes, and then measured it. Hope that helps. :-)

Hi.  We joined a CSA this year and I'm about zucchini-d out!  Looking for new ways to use them, I happened upon your site and this recipe.  These brownies look delicious and I am going to try them.  Do you have any suggestions for baking these at high-altitude?  I live at 8000 feet and don't have the best luck with baked goods.  
Reply Posted 9 months ago
Monica says:
Hi Betha. I wish I could help you, but I have absolutely no experience with high-altitude cooking. I've always lived in low-altitude areas. So, I'm afraid I can't recommend any needed adjustments. Sorry.

PS - I LOVE that you endorse Nordicware pans!  These are, hands down, the best pans I've ever used.  From roasting vegies, bacon, baked goods or under the bigger pan of lasagna, no matter how baked on or crusty they get, a short soak in hot water and they come clean.  And they're made in the USA.  Fantastic!

Misty says:
I added walnuts to the batter and the brownies did not appear to rise. Do walnuts do something to the ph of the batter to cause it not to rise?

PS - thanks for the recipe!

Monica says:
Hi Misty. I wouldn't expect the nuts to prevent the batter from rising. Hmmm. Not sure how to explain your results. It sounds like one of those baking mysteries to me. Just so you know, mine didn't rise a large amount--these brownies are fairly dense, not light and cakey.

Monica, I made these and loved them.  The second time, I made some substitutions though. I used a can of black beans, pureed, in place of flour and added two eggs.  My brownies came out fudgy and moist!

Tricia says:
So can I use cake flour instead of whole wheat flour?  I do not have a food processor- any recommendations for pureeing the zucchini?
Reply Posted 9 months ago
Monica says:
Hi Tricia. Yes, it's fine to use cake flour. Do you have a blender? That works well for pureeing the zucchini. If you don't have a blender, you can shred the zucchini with a grater instead of pureeing it. Although the brownies should still have good texture and taste once they're baked, the batter will be much thicker because the water in the zucchini doesn't get released from being blended. That will happen during baking though. Also, there may be visible bits of zucchini in the brownies--not a bad thing, just different from the pureed zucchini version.

I made these today and they were great! I used white whole wheat flour and I used melted butter because I really prefer it in my baked goods to oil (I guess a little fat doesn't hurt too much, especially since I left mine unfrosted) I'm a big dark chocolate fan and loved them and, to my surprise, so did my boyfriend who rolls his eyes at my putting whole grains and veggies in everything we eat. I might experiment around some next time by using a greek yogurt that comes already sweetened with honey and some applesauce and try to cut down the sugar. Thanks for a great recipe!

Monica says:
Hi Molly. Yum, the butter has to taste great in these. Using Greek yogurt sounds like a promising idea. If you try it, please come back and share your results. Thanks for the feedback! :-)

I just made these brownies and all I can say is WOW they turned out wonderful. I did however use splendia and I did add 3 bars of dark chocolate melted and then I added them to the wet mixture. I will be frosting mine soon. I think next time I will cut back a 1/2 cup on the flour and add a half cup of flaxmeal. Very good thanks!!!!!!!!!

Leslie says:
Hey- I very much liked this recipe, but just want to let you know that you're laboring under a fallacy. Dark or Dutch cocoa does NOT have more antioxidants. The dutching process using alkali to make it darker and less acidic also removes antioxidants. There's more in just regular cocoa. Just FYI :)

These brownies are so good, I`ve made them several times now and everybody loves them. I had to translate the recipe as a lot of people want it.  I veganized it - soyayoghurt, soyamilk and less sugar - and they are are just great. Thank you

Hey, just wanted to say I made these this week with regular cocoa powder and they were perfectly moist and delicious! Totally what I crave, very satisfying.  I also used regular whole wheat flour (sifted twice) and a stevia/sugar mix. I threw some choc. chips into the mix instead of a frosting. Mine didn't look done but passed the toothpick test. I'd suggest using an oil and not melted butter to anyone having issues with dryness. My son loves them too--thanks for posting this!

Hello Monica. I have being reading and trying your recipes for a while now and I love it. Today I just put in the oven a batch of this brownie for the first time. As always, every time I bake my 9 y.o. daughter licks the bowl... I was afraid she was going to taste the difference and decide not to eat the brownies after all since she is soooooooooooooo picky... Guess what! She licked the bowel and sai "This is FANTASTIC!!!".
Thanks for sharing it.

I used coconut oil and greek yogurt and found these to be dry, if you were to use the coconut oil, would you melt it first to make 1/4 cup?  I didn't, I used it more like shortening when I measured.  I'm thinking that could have been the issue...

However, the frosting recipe is FANTASTIC!  It's going to be my new standby.  YUM!
Reply Posted 3 months ago
Monica says:
Hi Kristen. I'm not sure about melting the oil; I don't think that should matter as long as it was packed and there weren't air pockets. My first batch of these turn out dry, and it turned out to be because I was baking them too long. I shortened the baking time, and since then they've come out moist every time. Maybe that would help you?

Rebekah Lowe says:
Do you think I might be able to substitute something alternative for a portion of the sugar without compromising the texture of these beautiful brownies??  I have from time to time cut sugar in recipes and used coconut sugar, agave nectar or even a little sweet dairy whey to reduce the white sugar in recipes, but hate to substitute on a tried and true recipe without asking.  
Reply Posted 2 months ago
Monica says:
Hi Rebekah. That's a good question. I'm afraid I really don't know the answer since I haven't tried any of the alternative sweeteners you mention in this particular recipe. My GUESS is that you could probably substitute for some of the sugar and get away with it. How much? Sorry, but I don't know without trying it. It may take some trial and error to get it right. Wish I could be of more help to you. If you try any of the substitutions, I'd love to hear how they turn out. :-)

My batter looks very dry compared to your batter using the regular cocoa powder. Mine has dark cocoa powder. Is this why? Or any suggestions? I used olive oil instead of coconut oil and a substitute sugar, but other than that- I used everything you did.

Monica's favorite gear for
making Zucchini Brownies
I use this in these brownies and to replace all or part of the white flour in other recipes. It has a finer, lighter texture than regular whole wheat flour.
Also available: gluten-free oat flour
I use this healthy, flavorful oil in place of vegetable oil in many recipes. It tastes great in these brownies; I also use it for popping popcorn.
I bake my brownies in these pans. I love that they have a cover and are easy to stack and store or freeze.
Also available: 9x13 baking pan with lid
Rated #1 by Cooks Illustrated, this is a workhorse! It does a great job of pureeing the zucchini in this recipe. Mine gets frequent use for blending frozen drinks, salad dressings, and more.
This is the Hershey's Special Dark Cocoa Powder I used in my zucchini brownies. It's yummy and high in antioxidants.
This gets a lot of use in my kitchen. Use it to whisk dry & wet ingredients, smooth frosting, gravy, and sauces, and for scrambling eggs.
I use these versatile bowls every day. Great for both mixing and serving. I love that they nest and can be stored compactly.
The bent angle of this spatula makes it much easier to apply frosting smoothly.
I use this durable spatula for mixing batter and stirring on the stove. It's heat resistant to 600 degrees and won't stain, melt or warp.
