My zucchini brownies are rich, fudgy, and naturally flourless. They are made using simple ingredients and are always a hit for dessert. No one will know there are greens hidden in them.
My zucchini chocolate cake remains one of my most-made recipes, so it’s a no-brainer to adapt it into fudgy brownies.
Adding zucchini to brownies adds moisture to the base, yielding extra fudgy and gooey brownies with crisp edges and crackly tops. Don’t fret, though- you won’t taste zucchini in them. I also appreciate that these brownies are healthier than traditional brownies and are quick and easy to prepare. Bonus? They are completely gluten-free.

★★★★★ REVIEW
“I give it a 10 on a scale of 1 to 10. The brownies taste even better than any boxed mix and no one knows there’s zucchini in them.” – Glenna
Ingredients needed
- Almond butter. I like to make my own, but any no-stir almond butter works well.
- Maple syrup. This liquid sweetener helps keep the middle of the brownies fudgy and balances out the sweetness. Honey and agave nectar also work.
- Brown sugar OR coconut sugar. Either of these sugars works. Go for coconut sugar if you want these brownies to be healthier. Of course, white sugar will also work.
- Eggs. room temperature, please.
- Vanilla extract. A must for any good chocolate dessert.
- Unsweetened cocoa powder. 100% Dutch processed and sifted. For a richer chocolate flavor, I sometimes use dark cocoa powder.
- Salt. To balance out all the sweet flavors.
- Baking powder. Leavening agent to give the brownies some rise and stability.
- Zucchini. Finely shredded zucchini with the moisture removed. I like to use a box grater for perfect shreds.
- Dark chocolate chips. Optional, but who doesn’t love brownies with pools of chocolate throughout?
How to make zucchini brownies
This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.
Step 1- Mix the wet. Mix the almond butter, maple syrup, brown sugar, eggs, and vanilla extract in a large bowl.
Step 2- Finish batter. Mix the cocoa and baking powder, then stir through the zucchini and chocolate chips.
Step 3- Assemble. Transfer the mixture into a lined square pan.
Step 4- Bake the brownies for 22-25 minutes or until a skewer comes out mostly clean.
Arman’s recipe tips
- Do not over-bake the brownies; they will continue to cook as they cool down.
- Always reserve a handful of chocolate chips to top the brownies with, as that guarantees tons of chocolate in every bite!
- Make sure to use good-quality cocoa powder for the most decadent chocolate flavor.
- Don’t overmix the batter; it can make your brownies tough and dry. Mix the wet and dry ingredients until combined, then gently fold the shredded zucchini and chocolate.
Storage instructions

To freeze: Place the cooled baked brownies in an airtight container and store them in the freezer for up to six months.
Frequently asked questions
Yes, and not just because of the zucchini. I cut back on the sugar and replaced half of it with a natural sweetener, maple syrup. I also omit any butter or oil and instead, use almond butter.
Yes, you can use frozen zucchini for this recipe. Thaw the zucchini completely and squeeze out any excess moisture before using them.

Notes
- Skip the eggs. Make them eggless by replacing the eggs with one of these egg substitutes.
- Cut the carbs. For low carb zucchini brownies, swap the maple syrup my keto maple syrup and use a brown sugar substitute.
- Change up the flavor. Add mix-ins like walnuts, coconut flakes, or even white chocolate chips.

These turned out great! Thanks for sharing Arman.
Excellent!! Can these be left out on the counter (in a container) for a few days or do they have to be refrigerated?
First I want to say these brownies look amazing😋, can I substitute the Maple syrup with honey? I’m not a fan of maple!
Yes you can!
Today made this! Just didnt use sugar and also used peanut butter. Amazing.
I’ve made these over and over but never without the brown sugar did you replace it with something else?
I’ve been looking for a healthy version of brownies, and every single one I had baked before it was a disappointment, until I baked this one….believe me this brownies came out amazingly good!!!!!! Thank you so much for sharing ❤️
I’ve made this many times sometimes with different nut butters. It always turns out great. Moist and not too sweet.
I tried this recipe. I am on a low carb diet for knee surgery! I made this not only for me but my daughter and grandsons! We all loved the flavor! It was not that sweet and it did not make the kids bounce off the walls. What an awesome healthy way to have something sweet for the whole family! Thank you for sharing! I saved your page for other recipes! You’re the bomb!
What can I use instead of maple syrup?
I eat zucchini very often but like salad. This can be amazing-healthy sweet without even the taste of veggies. Really need to try.
Parents can make this for their children!
Best fudgy zucchini brownies ever!
I made these brownies using sugar-free maple syrup, brown sugar substitute, and sugar-free chocolate chips. The brownies turned out delicious and fudgy-the best brownies I’ve made since I had to give up sugar 1 1/2 years ago. Fantastic recipe!
One question-you have different baking times in the discussion and in the recipe itself. I started checking them at 20 minutes, and baked them about 5 minutes longer, and they turned out perfect.
Thanks so much, Darlene! Oh yes i will fix it, thank you!!!
Great idea love to try this
Wow definitely need to try!
My medium zucchinis are quite different than my neighbor’s medium zucchinis. About how many cups, grated, are your medium zucchinis? Or by weight would be helpful please. 🙂
One cup is plenty 🙂
