Sneak veggies into your dessert with these healthy zucchini brownies that are made with almond and oat flour and naturally sweetened with maple syrup. They’re moist, fudgy, oil-free and gluten-free.
If you’re like me and always up to your ears in zucchini during the summer months, you need to make a batch of these brownies! Heck, even if you’re not swimming in zucchini, it’s worth picking one up at the store or farmers market to make them. They’re so good!
Zucchini is such a magical vegetable! It’s not only amazing in savory dishes, but it adds a wonderful texture and moistness to baked goods. Its mild flavor pairs beautifully with chocolate – making these brownies extra moist, boosted with nutrition and so delicious!
Why You’ll Love These Brownies
- Zucchini not only adds extra nutrition, but also extra moisture – no need for oil!
- They’re gluten-free, dairy-free and can easily be made vegan!
- No one will know that they’re made with good-for-you ingredients! They are still so rich and fudgy.
- oat flour – use store-bought oat flour or you can make your own using my oat flour recipe.
- almond flour – I recommend Bob’s Red Mill super fine almond flour. It’s perfect for baked goods and what I use for all of my almond flour recipes.
- cocoa powder – can’t have brownies without cocoa powder for that chocolatey flavor! Make sure you’re using unsweetened cocoa powder. Cacao powder works as well. I really like Navitas organic cacao powder.
- sea salt – brings all the flavors together.
- baking soda – to help the brownies rise.
- eggs – helps bind the ingredients together and provide structure for the brownies.
- maple syrup – one of my favorite natural sweeteners. Just be sure to use pure maple syrup, not the artificial kind labeled “pancake syrup” that’s made from corn syrup.
- vanilla extract – a flavor enhancer.
- zucchini – the star of the show here. There’s no need to squeeze the grated zucchini… the liquid from the zucchini replaces the oil and helps to keep these brownies moist.
- chocolate chips – I recommend Enjoy Life dark chocolate chips which are allergen-friendly or Lily’s chocolate chips because they are lower in sugar and calories.
How to Make
Making these zucchini brownies is incredibly easy.
In a medium mixing bowl, start by combining oat flour, almond flour, cocoa powder, sea salt and baking soda. In a large bowl whisk together eggs, maple syrup and vanilla extract. Add zucchini shreds and stir to combine. Pour dry ingredients into wet ingredients and mix until just combined. Gently fold in the chocolate chips.
Grease an 8×8 inch baking pan or line with parchment paper. Pour the brownie batter into the prepared pan. Bake at 350ºF for 30-40 minutes. You’ll know the brownies are done when a toothpick inserted into the center comes out clean.
Let the brownies cool completely before cutting and serving. Trust me… they taste better cool!
Substitutions & Notes
- Flour: I’ve only tested this recipe with a combo of oat and almond flour and don’t recommend subbing for any other flour.
- Eggs: I have tested these brownies with flax eggs and they turned out great, so if you need this recipe to be vegan simply swap the 2 eggs with 2 flax eggs.
- Maple syrup: I haven’t tried substituting the maple syrup for another sweetener like honey or agave, but I bet it would work. If you decide to experiment, let me know how they turn out.
- Chocolate chips: Instead of chocolate chips you could try a different mix-in like chopped pecans or walnuts.
How to Serve
I love eating these brownies plain, but if you want to get fancy here are some topping ideas:
- Nut butter – you can’t go wrong with a drizzle of nut butter to top! Almond butter would be my top choice, but I bet peanut butter, cashew butter or even tahini would all be delicious.
- Coconut whip – these brownies would be delicious with a dollop of coconut whip cream on top!
- Ice cream – brownies + ice cream = a match made in heaven. These brownies would be delicious warmed in the microwave and served with my banana ice cream, chocolate banana ice cream or avocado ice cream.
- Caramel sauce – I’m drooling just thinking about how delicious my date caramel sauce would be drizzled over one of these brownies.
- Yogurt – want to eat a brownie for breakfast? Crumble it on top of some Greek yogurt (or any yogurt of choice) with a sprinkle of granola (this hemp granola is delicious) and fresh berries. Like a breakfast brownie sundae… so yummy!
- Oats – another breakfast idea is to crumble a brownie on top of overnight oats like these zucchini bread overnight oats.
How to Store Leftovers
Store brownies in an airtight container at room temperature for 3 days or in the refrigerator for up to 1 week. For longer storage, I recommend freezing. Store in a freezer-safe, airtight container in the freezer for up to 3 months. I like to use my Stasher bags or these glass containers for easy storage.

I made these tonight and my husband and I both loved them! The zucchini does a great job of keeping them moist with no added oil, which is pretty impressive. They taste just like brownies, what else can you ask for?

Omg these brownies are moist & delicious! They come together super easy. Everyone loved them! Will definitely be making these again and again. Your recipes never disappoint!
YAY! I am so glad that this recipe was a hit, Diane. Thank you for your review + star rating, I really appreciate it!
Sounds yummy! Do you think I could use coconut flour instead of almond?
Hi Olivia – I’ve only tested this recipe with a combo of oat and almond flour and don’t recommend subbing for any other flour. If you give these a try, I’d love to hear what you think of them!
Thank you! These were simple and easy to follow ingredients and taste great. They aren’t too sweet! I didn’t put the chocolate chips at the top. And it’s wonderful.
So glad you enjoyed these brownies, Dody. Thanks for making them and for coming back to leave a review. I so appreciate it!!
I made these yesterday and OH MY GOSH THEY ARE SOOO GOOD! They are so moist and perfectly balanced between gooey chewy fudgey and fluffy soft cakey! I was worried that they would be a bit dry but they are the most moist brownies I’ve ever had without being at all mushy. I added about 3/4 of a packet of instant coffee just because I love the way it makes chocolate taste and I add it to every chocolate thing I make and it was definitely a good choice. My dad refuses to eat vegetables and has zero clue that theses delicious brownies are full of zucchini😆 Thank you so much for this recipe! Also, they somehow taste even better the next day😊👍🏽💕
Oh yay!! This makes me so happy to hear. I’m so glad you loved these brownies!! Thanks for making them and for coming back to leave a review. I so appreciate it.
Unfortunately half of my family members did not like these. I personally enjoyed them but would not make again. I would recommend making these brownies if you would like to try something new.
Sorry to hear that these brownies weren’t a hit with your family. Thanks for giving them a try, Emily!
These were amazing, so moist and we used dark chocolate! My kids loved these! Omg yum! We got 16 servings so felt less guilty mentally eating 2 squares lol.Better than regular brownies!
Ah yum! I am so glad that you and your family are loving this recipe, Caitlin. Thank you so much for sharing your review + star rating, I so appreciate it.
The brownies are excellent & will definitely make them again. I used chopped dates & maple syrup, (the same as the writer above) coconut milk to thin the batter a little & chopped walnuts…. Perfect…
Yum! This sounds amazing, Arleen! I am so glad you loved this recipe. Thank you for coming back and sharing your review + star rating, it means so much to me!
Do you think I could do 1 cup of oat flour instead of 1/2 cup oat flour and 1/2 cup almond flour? We have a nut allergy.
Hi Kelli – I have not tested this recipe with just oat flour, it should work, but it might turn out a bit more dense. The oat flour is a bit heavier than almond flour. If you give this recipe a try, let me know how it turns out for you! Enjoy!
