These vegan zucchini brownies are incredibly rich and gooey. They are a decadent dessert bar with hidden vegetables for added moisture plus healthy benefits! Whip them up in under 15 minutes!
Who wants a chocolatey fudgy vegan brownie?
I do! I do!
It's been said, more than once, that this is the BEST brownie recipe ever. And I have to say I agree. This rich and fudgy brownie is perfect. It is rich with chocolate, gooey and fudgy, and made ultra-moist with shredded zucchini.
The zucchini taste isn't detectable but it adds an incredible texture while giving use for all those zucchinis popping up in your garden.
Not only that, but this recipe is super easy to master. These brownies are made with just 9 ingredients (that you probably already have on hand) and can be baking in the oven for just 20 minutes. And best yet, they are fool-proof. If you can mix, fold, and bake, then you can make this recipe.

Ingredients & Substitutions
Here is everything you need.
- Oil - This recipe calls for melted coconut oil or avocado oil. However any oil without a strong flavor works.
- Brown Sugar - Check out my guide to vegan sugars and alternative sugar replacements. For a healthier sugar alternative, I recommend brown coconut sugar.
- Vanilla Extract
- All-Purpose Flour - For a gluten-free brownie, you can use a 1:1 gluten-free flour blend.
- Dutch Cocoa Powder- I always prefer Dutch as it is a bit smoother and less acidic but regular cocoa powder works as well.
- Baking Soda
- Salt
- Shredded Zucchini
- Vegan Chocolate Chips
Step-by-Step Instructions
Step One - Shred the Zucchini
Using the shredding attachment of your food processor or handheld grater, shred the zucchini. This recipe calls for 2 cups of shredded zucchini which is about 1 large zucchini or 2 small zucchinis.
Pro Tip: Do not squeeze out the moisture in the shredded zucchini. The extra moisture is needed to make these brownies fudgy and delicious!
Step Two - Mix the Ingredients
In one bowl mix together the dry ingredients. That's the flour, cocoa powder, baking soda, and salt. In a separate bowl, combine the oil, sugar, and vanilla extract.
Gently fold in the shredded zucchini and chocolate chips.
Step Three - Pour into Pan and Bake
Pour the batter onto the prepared baking sheet and bake for 35-45 minutes.
Keep an eye on those brownies and pull them out when they are slightly underdone – a toothpick inserted in the middle should come out with a few moist crumbs – as they will continue to harden as they cool.
Let the brownies cool completely before taking them out of the baking dish and serving.

Serving and Storing
Serving - When ready to remove from the pan, pull up on the overhanging parchment paper. Slice into 2" pieces. Serve the brownies at room temperature or rewarm them and serve them with some coconut ice cream for a delicious dessert. So good!
Storing - Store the brownies in an airtight container at room temperature for up to 5 days. You can also wrap the brownies in plastic wrap and place them in the freezer to store for up to 2 months.
Tips and Tricks
- Do not squeeze out the moisture in the shredded zucchini. The extra moisture is needed to make these brownies fudgy and delicious!
- Be careful not to over-mix your batter. This will encourage the gluten to form making your bars gummy and dense.
- Line your baking sheet with parchment paper so that brownies do not stick to the pan.
- Make sure to let the brownies cool completely before removing them from the pan and slicing. Use a sharp knife and clean it off between each cut so that you can get clean, crisp edges
Frequently Asked Questions
Nope! Zucchini is relatively flavorless and takes on the flavors of the chocolate. Zucchini simply adds texture and moisture.
Yes! I’ve had luck both with a 1:1 gluten-free flour blend as well as buckwheat flour.
Indeed! While it will change the texture slightly, you can replace the oil with ½ cup applesauce for an oil-free brownie.
While I haven’t tried it personally, I’ve had readers who have reduced the sugar by half and still love the brownie. You can also check out my guide on healthier sugar alternatives for some ideas on how to replace the sugar.
If you have extra shredded zucchini, you can freeze it by placing it in a single layer on a baking sheet. Once the zucchini is frozen all the way solid, transfer it to small glass jars or Ziplock bags. Leftover zucchini is great for adding moisture to bread, muffins, or used as an egg replacer in common baked goods.

Fudgy Zucchini Brownies
Ingredients
- ½ cup avocado oil or melted coconut oil
- 1 ½ cup brown sugar
- 2 teaspoon vanilla extract
- 2 cup all purpose flour
- ½ cup cocoa powder
- 1 ½ teaspoon baking soda
- 1 teaspoon salt
- 2 cups shredded zucchini
- 1 cup vegan chocolate chips
Instructions
- Preheat the oven to 350F. Line a 9x9 baking dish with parchment paper so that the paper hangs over opposite sides. Set aside.
- Shred the zucchini in a food processor with the shredder attachment or with a handheld shredder. Set aside.
- In a stand-up mixer or large mixing bowl, mix together the oil, sugar, and vanilla extract. In a separate bowl combine the flour, cocoa powder, baking soda, and salt. With the mixer running, slowly add the dry ingredients to the wet, beating it until it's well combined. The dough will be dry at this point. Don't worry. The zucchini provides the moisture.
- Add the zucchini and gently mix together. Fold in the chocolate chips.
- Pour the batter onto the prepared baking sheet and bake for 35-45 minutes. You want the brownies to be slightly under-baked so that a knife inserted in the middle comes out with moist crumbs on it.
- Let the brownies cool completely before taking them out of the baking dish. When ready to remove from the pan, pull up on the overhanging parchment paper. Slice into 2" pieces.

Aimee B. says
These are soooooo good! I made a half batch because I only had 1 zucchini and they came out amazing. They're so fudgy & moist. No one even know there was zucchini in them. I baked mine in a small roasting pan, in my toaster oven for about 18-20 minutes, and they were perfect. I'll definitely be making these again. 🙂
James says
So moist and decadent. My family went nuts for them and they were gone in a day. Super easy to make too.
Amanda says
These brownies are incredible! Lick your fingers good! I will be making them over and over again.
Judy says
I've been experimenting with vegan recipes (not yours) and they haven't come out great. I was thinking if this one doesn't work out - I quit for now because of difficulty in getting certain ingredients - can't afford to waste and mess around. You've restored my confidence. This recipe is ah mazing. Thank you! This is delish.
Jane Thompson says
This is a excellent cake but not a brownie. With two cups of flour in an 8x8 pan they came out double the height in the picture. Came out more like devils food cake. Great recipe just not sure the pan size/flour amount are accurate?
Tania Bull says
Will never make any other brownies ever again - these are by far the BEST!! Have forwarded the recipe to all my girlfriends, 10/10 LOVE
Kathie says
I use many of your recipes and they are wonderful. BUT please, please use less or no sugar. We are trying to use monk fruit so I will make these without all the sugar and see how they turn out. Will let you know how they turn out.
Jojo says
These look great, I enjoy hiding veggies in cake occasionally!

hastalavegan says
Yay, congrats! This is yet another blog that has escaped my attention this year round, so I will be catching up on your posts in the near future. These brownies look so delicious and fudgy! I'm always on the lookout for courgettes to go in my baked goods.
Also congrats on your vegan anniversary! It was similar when I went vegan, I did kind of do it on a whim and didn't have a great track record, but here I am almost 8 years vegan myself and my friends and family still can't quite believe it.
Jennifer Manriquez says
Wow! These look amazing. Can't wait to try this recipe!
