Chocolate Zucchini Brownies have a vegetable hiding inside, but you'd never know it! This recipe is naturally vegan, fudgy, healthy and delicious.
They're moist and have a rich chocolate taste! We love the magic of zucchini shreds so much in this recipe that we used them in Death by Chocolate Zucchini Muffins and Healthy Zucchini Muffins too.
Go ahead and indulge in one before dinner. You're eating vegetables after all. 🙂
In case it's not obvious from posts on zucchini noodle alfredo or zucchini chips from the microwave, we're a little obsessed with this vegetable. It can do just about anything!
National Zucchini Day, happens to be on August 8th, but don't wait to try these!
Tips to Make Chocolate Zucchini Brownies
Making these brownies isn't much different than making a traditional one, except that zucchini shreds are added and the result is a very moist and delicious treat! There's a video recap just before the recipe instructions.
Zucchini Brownie Batter Ingredients
To make the batter:
Bowl 1: Mix together sugar, canola oil and vanilla extract until well-combined and crumbly. We used a combination of sugar and a stevia blend in order to keep with the healthy theme of this brownie.
We've also used olive oil instead of canola oil. It works!
Bowl 2: Combine flour, cocoa powder, baking soda and salt.
We used unbleached all-purpose flour to make the zucchini brownies pictured. We use whole wheat pastry flour these days.
Combine: Stir the sugar mixture into the flour mixture. It will have a crumbly texture as shown in the picture below. It won't feel like regular brownie batter at this point.
In case you're wondering, one bowl can be used instead of two. We find that the ingredients are more evenly distributed when we do it this way.
Prepping the Zucchini Shreds
Grate a zucchini, skin and all, until you have two cups of shreds. We used one pretty large zucchini and had some leftover. If this happens to you, make Zucchini Egg Muffins or Zucchini Fritters with Feta!
Unlike other recipes, a little moisture is a good thing. There's no need to press out extra wetness. Usually.
Use a large-holed grater for the best results. If a small-holed grater is used, you might need to because you'll end up with more water.
What should the batter look like?
It's an important question so we are pausing to talk about it and view a picture! The batter will be thick.
Fold the zucchini into the flour and sugar mixture and stir until distributed throughout. The batter becomes wetter as the zucchini shreds are incorporated. So, stir well.
If for some reason the batter is just too thick, then add a teaspoon of water.
Scrape it into a baking dish. Have faith. A magical process occurs during the cooking process transforming the final product to a moist and chewy brownie.
These chocolate zucchini brownies are the real deal. They are vegan, healthy and delicious. And, you can't taste the zucchini, despite what one of my darling daughters might tell you!

Deeelicious , yet nutritious, moist mouthful of heaven!
Thanks for sharing!!!
Kat
Are there any nutrition facts/calorie info for this? Just curious.
Marjory
Hi! Unfortunately I don't have any nutritional information. But, using a stevia blend reduces the amount of refined sugar...and it does have zucchini in it! Thanks for reading.
Danielle
I just did the nutritional info on these in MyFitness Pal. 222 calories based on 16 servings. 7.8 fat, 35.8 carbs, 3.8 protein. Someone else commented you could change half out of the oil for unsweetened applesauce and half the flour with whole wheat flour too. That could help reduce calories too! Can't wait to try these! Thanks!
Marjory
Thanks for sharing these great tips!
Melinda
I just made these and they are sooooo good!!
Marjory
Yay! I'm so glad you liked them!
Shannon
These are great. I made them healthier by replacing half the oil with applesauce, half the flour with whole wheat flour and half the sugar with Splenda for baking.
Marjory
Thanks for sharing the healthy tips!
Jasmine
Hello, i really want to try this recipe, will it make a big difference if i use bleached flour as opposed to un-bleached flour?
Marjory
Hi! It should work out fine with all purpose flour too.
April von
I just love everyone’s love for great food and for learning to use zucchini in a whole new way ... I grow zucchini and just have so much I do not know what to do with all of them most times except give them away . Thank you all ♥️
Marjory Pilley
Sounds heavenly! I bet you have some wonderful ways to prepare it!
April von
I use shredded zucchini in my meatballs ,it makes them incredibly tender and moist ! And guess what moms ... if you have a hard time getting the kids to eat veggies ,this is the best way to hide them .❤️
Marjory Pilley
Genius! I'm a meatloaf muffin fanatic...I'm going to try it in a version of those!
Stephanie
There were really yummy. Just go done making them with my boys. They are pretty picky, but gave them a definite thumbs up! "Mom you can't even taste the zucchini!" was what I kept hearing. Thanks for sharing.
Marjory
I'm so glad everyone liked them!
Denise
Has anyone tried feeding the finished results? I was wondering if I could make a few batches, freeze, and enjoy later.
Marjory
I have not tried freezing these...but, I think it's definitely worth a try!
Danielle
These were delicious! I would never know they were vegan I was suprised the texture was perfect, and would never know they have zucchini in them! I followed the recipe pretty much exact (I used veggie oil instead of canola). Next time I might try whole wheat flour and coconut oil and add some type of nuts.
Marjory
Thanks for your feedback. Love your ideas for making them even healthier!
Shandeb
Brava ! I hate most veggies and of course that's all I'm _supposed_ to eat. Could I grate the zuke and add it to soup or into a spaghetti tomato sauce to have with pasta? Also what spices go with zukes',please?
Thank you for your great creative ideas . I need lots of help learning to cook 😉
Marjory
Thanks for stopping by! Grated zucchini is awesome in soup and can act like pasta too! As for spices, it depends what you are using it for. If you are using it in spaghetti, a little oregano might be nice. But, I usually just sprinkle with a little salt and pepper.
Heidi
I love zucchini with basil. I sliced some really thin the other night and put them on homemade pizza. You can cut them in half lengthwise and scoop them out a little (just the seeds) then fill with meat, sauce and cheese then bake. There are a ton of recipes online for zucchini. I used a bunch the other day with a jar of last year's apple butter to make a bread. Good luck and have fun experimenting!
By the way, my batch just went in the oven. I always sub coconut oil nowadays and am excited to eat one. I also realized after I started that I am out of baking soda so I did a 1:4 baking powder substitution. I think they are going to survive the alterations just fine 😉
Marjory
Sounds like a delicious way to enjoy zucchini! Thanks so much for your comments!
elisa
hi there,
how can I make this recipe gluten free. thanks
Marjory
You should be able to replace the flour with a gluten-free type, such as the one Bob's Red Mill makes. Thanks for your question! I hope that helps.
ada
Thanks for sharing. I made these last night in celebration of surviving day 20 of a 22 day Vegan Challenge! I cut back on the sugar and oil a bit and they were very tasty. I will make these again and again.
Marjory
Congrats on your challenge! Thanks for your comment.
KC
These are my new favorite vegan brownie recipe! Thank you!
Marjory
I'm so glad you liked them!!!
Robyn
I made these today - I used 1/4 cup coconut oil & 1/4 cup applesauce in place of the canola oil & I had to add a few Tablespoons of almond milk (because I think I squeezed out too much liquid from my zucchini), but they turned out really moist & delicious. Mine were more cake-like (probably because of the applesauce), so I added a simple glaze of powdered sugar, vanilla, milk, & a tad of butter. So good! My husband & kids didn't even notice the zucchini. I will be keeping this recipe & making these again! Thanks!
Marjory
Thanks so much for your feedback. Your changes sounds fabulous and I'm craving some brownies now. 🙂
Maria
Did you squezzee your zuchinni?
I ma ready to Make them but it doesn't specify
Thanks
Marjory
Hi! Blot dry, but you don't need to squeeze it dry. Thanks for your question and I hope you enjoyed them!
Rannie
Omg!!!! I don't need to search another recipe for chewy brownies!!! This is it! I was a bit skeptical because the batter was too crumbly looking texture but I didn't need to worry about that at all!! It came out perfect chewy inside and crunch outside brownies!!! Thank you for sharing!!!!
Marjory
thanks for your comment. I think I was skeptical the first time I used zucchini in a dessert...but, now it is my favorite brownie!
rebecca
These were so good! My whole family loved them. I did make some changes. I added applesauce instead of oil, 1/4 cup flax seed with the flour, 3/4 cup cocoa since I like extra chocolate, 1/2 cup chocolate chips, 1 egg since I have chickens and needed to use them, and 1 cup rhubarb since I have an abundance of that too. They were chocolaty with bites of tart rhubarb. Didn't even know the squash was there. They were more cake like than brownie like but delicious.
Marjory
Wow! Love your version. Thanks for sharing!
Laura
Great recipe! Will definitely make it again! Thanks for sharing!
Marjory
I'm so glad you liked it! 🙂
Sandra
Not sure why I didn't have as great a success as the other people here. Once I had all of my ingredients mixed together (zucchini included) it wasn't nearly as thick & moist. It would ball up if you pushed it together, very crumbly like step 1. I thought maybe I had missed an ingredient or mixed up a measurement but I didn't find any. I ended up adding a bit more oil and zucchini to get a little more moisture but it didn't seem to help.
I'm a novice baker so I figured I'd trust the recipe and throw it in the oven. It did come out nicely but not like a brownie, more cake-like. It also isn't nearly as sweet as if I had used regular sugar (instead of the modified stevia amount).
Still pretty tasty when all is said and done (definitely can't tell there's zucchini in it!); I was just wondering if anyone had any feedback that might lead me in the right direction!
Marjory
Hi there! It's really hard to tell what might have happened. The zucchini usually adds lots of moisture. I wonder if your measurement for zucchini shreds was different...it sounds like it was a good idea to add more shreds. 🙂
Meg
I LOVE these brownies! They always seem to take a bit longer than posted to bake for me, but I love I them! I typically add less sugar and add raw honey to sweeten. I like the idea of doing applesauce in place of some oil too! One question, how should they be stored? Fridge or counter?
Marjory
Thanks so much for comments. Love your substitutions. I store them in refrigerator...when I have any leftover!
Oscar
So glad I found this recipe, it's genius!
Just made it and the brownies are seriously delicious.
A big thanks and greetings from Germany!
Marjory
I am thrilled that you found me all the way from Germany and that you liked the recipe! Cheers!
b
Yummy...eventually! After mixing all the ingredients, my 'batter' was super dry it wouldn't even come together. I did not squeeze out any moisture from the zucchini. Maybe if I let it sit for a while the zucchini would have moistened the batter? SO, I added about 1/4 cup of applesauce (actually one squeezable unsweetened applesauce pouch), and that was the perfect addition to make my mix an actual batter. I was a bit worried I would feel/taste the zucchini as there was a lot in the batter, but the end result was a super moist brownie that my 3 and 7 year old (and I) devoured!! My husband thought it was a bit too moist, but he didn't let it cool before he ate the first piece. I'm keeping recipe to definitely make again!! Thank you!!
Marjory
Great tip! Thanks for sharing.
C
I've made these twice and they don't cook either time. I even left them in 10 extra minutes and it's completely raw. It must need a higher temp or significantly longer cook time.
Marjory
I'm so sorry. Could the zucchini still have a lot of liquid in then shreds?
cathie
i added an avacado and it was yummy!
Marjory
I can't wait to try this! 🙂
Maggie
These were so yummy. Moist and chocolately, plus I even had veggies! A win-win for all eaters. I brought these to a party and everyone raved. I didn't tell them there were zucchini in them. My secret. Delicious. I think these might be added to my tailgate parties.
Becca
I tried these and they were good. Mine turned out to be more of a cake than brownies but the receipt was still good!
Marjory
I'm so glad you enjoyed them! 🙂
April
I've been wanting to try a zucchini brownie recipe. I think I just found the one!
Marjory
Enjoy!
michele
These were so good... and perfect timing as I had leftover zucchini from my chicken noodle dinner last night! I hope these make it to the weekend.... but I seriously cant quit eating them!
Marjory
I'm glad you enjoyed them! They never last long at our house either.
Candy
We loved the brownies, took some to work and the were gone in no time. Thank you for sharing your recipe.
Marjory
I'm so glad you enjoyed it!
Michelle
I don't understand the reviews. I wasted time and energy on something I wanted to take to a special event and I'm so glad I tasted them first. SO bitter...did not even taste like a dessert. Coukd not even taste much chocolate flavour either. I literally had to throw them out. I used the 1/4 sugar as I don't use stevia.
Marjory
Hi! It calls for 1 and 1/4 cup regular sugar. I'm so sorry they didn't work out.
DanDan
Hi Michelle,
I unfortunately had the same result. I also made them for an event and threw them in the bin. The texture was perfect, I had to bake for a little longer (maybe my zucchini's had more liquid in them), they looked fabulous.
BUT, they had absolutely no taste. I followed the recipe exactly. I chalk it up to perhaps we just have different palates and mine doesn't work for this recipe.
Marjory
Hello! I'm so sorry they didn't work out for you. Is it possible that you did not use the full amount of sugar (it calls for 1 AND 1/4 cup of regular sugar or the equivalent of a sugar substitute?)
JulieD
Wow! I’d never made zucchini baked goods before. I’m so happy I found this recipe! Holy Moley! I will make these weekly as the zucchini continues to roll in. I used EVOO, 1 cup of sugar and added an egg. I’m not vegan. This is a keeper recipe. Can not wait to try all the variation ideas. Kudos!
Marjory
Yay! I'm so glad you enjoyed it! and yes...it is fantastic with olive oil! We've been doing that too lately! Thanks for tip!
Anupa
This recipe turns out amazing! I literally threw everything together and mixed it and baked it. I substituted 1/2 cup flour for almond flour and it is still amazing. Thank you!
Marjory
Thanks for your comment! So good to know that it works with almond flour!!!
Patty
Making the second batch of these in two days! First one fed to "old" men at work. Loved seeing their faces after I told them they were filled with zucchini and vegan! 🙂 Everyone loved them! So now making a batch for home. These are perfect for using up all the summer zucchini!
Marjory
Made my day!!! 🙂 So glad you're enjoying them!!!
Ajs
Very dry and crumbly. Not fudgy at all. Not surprising as there I no liquid other than the zucchini.
Marjory
Don't forget to add the oil!!!
melissa
Can you make these with coconut flour?
Marjory
Hi! I've never made zucchini brownies with that substitution. You would need to use much less coconut flour. I believe the substitution is about 1/3 cup coconut to replace 1 cup of flour. Good luck and please write back if you give it a try!
Jennifer
This recipe is an absolute keeper! Thank you for sharing, Marjory. I do honestly believe the brownies were much better post refrigeration.
Marjory
I'm so glad you enjoyed them!
Nicolle
These did not come out well for me. The sugar never completely dissolved and it was too sweet. It needs an egg or other moisture. The top still looked like a crumbled mess after baked. They were fudgy though.
Marjory
I'm so sorry that they didn't work out for you! An egg can definitely be added to the recipe. However, it seems like something may have been off because we make without egg all the time without any issue. Perhaps too much zucchini?...Would be happy to help you troubleshoot if you decide to make it again.
Brittney
What a pleasant surprise! My fiance and I are new vegetarians and are trying to be more aware of what we feed our bodies and sometimes that means our sweet tooth goes unsatisfied. I was so excited when these came out of the oven looking and tasting like delicious brownies. The zucchini doesn't make the texture weird or crunchy, it makes it gooey and delicious. I made these with all-purpose whole wheat flour and olive oil and had to add a little warm water to the batter to make everything come together. Thank you for sharing this great recipe :)!
Marjory Pilley
I'm so glad you enjoyed it! Love the olive oil tip!
Sonya
These are Delish!!! I did alter the recipe a bit... I traded out the canola oil with coconut oil and the stevia for coconut sugar and used 100% whole wheat flour...Yum!!! Definitely making this one again!!
Marjory Pilley
So glad you enjoyed them!
Tina
For those with gluten allergies/sensitivity, substitute gluten free flour blend.
Marjory Pilley
Thanks so much for sharing that tip!
Joyce
So rich and moist! I will definitely make these again.
Vikki
Definitely chocolatey and moist! My family loved them! However, I must have done something wrong, as the texture was more cake than fudgy brownie. Didn’t really matter; the result was delicious!
Lori
The best, most delicious moist brownies I’ve ever made!
Susan B
These are so good and we’re perfect for my group with allergies. They’re nut free, dairy free, no eggs, and my group of teens loved them!
Marjory Pilley
I'm so glad you enjoyed them!
Jackie
I have the artificial sweetener intolerance so I can’t have Stevia. How much regular sugar should I use? 1 1/4 cups?
Marjory Pilley
Hi! Yes - use 1 1/4 (1.25) cups. Enjoy!
Julianne H
I didn't think there was any way my kids would eat these brownies since the zucchini is visible, but I was wrong. Maybe it helped that they made them with me. My daughters and nieces thought these were awesome (so did the adults). My sister-in-law asked for the recipe, since her kids struggle to eat veggies just like mine do. I've now made this recipe 5 times. I tried one batch with applesauce instead of oil and it worked OK, but was better with oil.
Marjory Pilley
Yay!!! So glad you turn them into fans! Thanks so much for circling back to share your comment.
Ken
My wife liked them, but they're not my idea of a good brownie. Could be more chocolaty and a little sweeter (I used 1-1/4 cups of regular sugar). But the main thing was the whole wheat flour gave it a flavor and texture that I don't want in a brownie. And I only used half whole wheat and half unbleached flour. I might try it again with no whole wheat and more sugar or add some chocolate chips.
