Love zucchini desserts? Try my healthy zucchini muffins, healthy chocolate zucchini bread, and chocolate zucchini cake.
My family find it amusing when zucchini are in season because besides zucchini fries, I tend to use this veggie for desserts. While they are always fans of them, my zucchini brownie is their absolute favorite…and mine too!

★★★★★ REVIEW
“I give it a 10 on a scale of 1 to 10.” – 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.
- 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. A pinch of sea salt will transform the flavor and texture.
- 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
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- make the batter. Mix the almond butter, maple syrup, brown sugar, eggs, and vanilla extract in a large bowl. Mix through the cocoa and baking powder, then stir through the zucchini and chocolate chips.
Step 2- bake the brownies. Transfer the mixture into a lined square pan and reserve some chocolate chips to place on top. 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 for topping the brownies with, as that guarantees tons of chocolate in every bite!
- Make sure to use good-quality cocoa powder for the richest chocolate flavor.
- Don’t overmix the batter, as it can make your brownies tough and dry. Mix the wet and dry ingredients until combined, then gently fold the shredded zucchini and chocolate.
Dietary swaps and variations
These brownies are super forgiving, so you can easily adapt them to other diets or change up their texture by adding nuts, frosting, and more:
- 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.
- Replace the nut butter. Substitute the almond butter for peanut butter, cashew butter, or a nut-free alternative like tahini.
- Frost it! Add some frosting, like a chocolate frosting or a healthy frosting.
Storage instructions
To store: Leftover brownies can be stored in the refrigerator, covered, for up to two weeks.
To freeze: Place the cooled baked brownies in an airtight container and store them in the freezer for up to six months.

Can I use regular butter instead of almond butter?
Has to be a nut or seed butter!
How much zucchini? I have a very large zucchini and don’t know how much (in cup size) would be the equivalent of a medium zucchini. Thanks!
1/2 cup is usually fine, but I can sometimes get away with a full cup!
When you say shredded zucchini, moisture removed, do you mean towel squeezed?
Yes, or just by hand is fine too!
My daughter liked these but I found that they were moist but lacked sweetness.
Can you give some guidance as to about how big a medium zucchini is? Or about how many cups of shredded zucchini it should measure out to? Your idea of a medium zucchini and mine might be totally different.
About one scant cup 🙂
best cookie bars I’ve ever made!
Stellar!!
(Gotta admit, I was skeptical, but it worked perfectly! Delicious!)
You’re batting 1000 in my book!
Thank you, Arman!!
I give it a 10 on the scale of 1 to 10.
Best flourless brownies I’ve had!
Can I sub Monkfruit sweetener? Or Swerve brown sugar?
You could, but it will be grainy 🙂
Chocolate and fudgy. Yum. I couldn’t taste the zucchini. I added chopped walnuts and the brownies held together beautifully. I processed my zucchini in the mini food chopper until it was like a paste and then drained it through a fine mesh sieve. These brownies satisfied my sweet craving. I made them so I could enjoy a sweet and everyone ended up enjoying them.
can we substitute your real brown sugar 1:1 with briwn swerve? or is there a special conversion needed? and same question for switching your real maple syrup for low-carb maple substitute?
How much zucchini does this equate to? I have frozen shredded zucchini so I’m looking for an approximate measurement. Thanks!
approx. 1 cup .
Spectacular just as is! Will make again and again!
Hi! These look delicious! I have a garden with HUGE zucchini to eat up. Do you have an approx weight of the zucchini that you used or a cup measurement of grated zucchini that you used for these? My zucchinis have passed the medium stage!!!
