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 zucchini brownies.

Adding zucchini to brownies adds moisture to the base, and with the richness of the almond butter and the combo of maple syrup and coconut sugar, yields extra fudgy and gooey brownies with crisp edges and crackly tops. Don’t fret, though- I tested this recipe many times to ensure 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 entirely gluten-free.

Zucchini brownies recipe highlights

  • They are healthier. These brownies don’t use any flour or refined sugar, so even without the zucchini, they are already a healthier dessert!
  • Quick and easy to make. Once you’ve made the batter, the brownies bake in 25 minutes.
  • You can make it diet-friendly. Not only are these brownies naturally gluten-free, but you can make keto zucchini brownies with a few minor tweaks.

Key Ingredients

ingredients for zucchini brownies.

Find the printable recipe with measurements below.

  • Almond butter. I like to make my own, but any no-stir almond butter works well.
  • Maple syrup. This helps keep the middle of the brownies fudgy and balances out the sweetness. I also tested these with honey and agave, which both worked well.
  • Brown sugar OR coconut sugar. Either of these sugars works. Go for coconut sugar if you want these brownies to be healthier. 
  • 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 (labelled as black cocoa powder).
  • Salt. To balance out all the sweet flavors.
  • Baking powder. To give the brownies some rise and stability. 
  • Zucchini. Finely shredded zucchini with the moisture removed. Do not peel the zucchini! I like to use a box grater for perfect shreds but a cheese grater is fine.
  • Chocolate. Optional, but who doesn’t love brownies with pools of chocolate throughout? You can use chocolate chips for even more chocolate, chop up a chocolate bar.

Zucchini size matters

When developing this recipe, I tested it using one zucchini each time, and the results varied depending on its size. To guarantee consistent results, I now use a cup measurement instead. You’ll need one cup of shredded zucchini with the excess moisture removed- this might be one small zucchini or several, depending on the size.

To measure, shred the zucchini, squeeze out the excess moisture, then pack it into a 1 cup measure.

★★★★★ 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

Recipe tips and variations

  • Don’t add extra zucchini. Even a little bit more zucchini over the one cup recommendation can result in underbaked and non-fudgy brownies.
  • Do not over-bake the brownies; they will continue to cook as they cool down. I recommend removing them from the oven once a toothpick comes out mostly clean. Check at the 22-minute mark.
  • 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 in the shredded zucchini and chocolate.
  • Cool before slicing. I know it’s tempting to dig right in, but because we’re NOT relying on flour for structure, the brownies are fragile until they reach room temperature.
  • Make keto zucchini brownies. Replace the sugar with keto brown sugar and the maple syrup with keto maple syrup. Bake as instructed, and each brownie will have just 4 grams of carbs.

Frequently asked questions

Are these brownies healthy?

Yes, and not just because of the zucchini. When creating this recipe, 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.

Can you use frozen zucchini?

Yes, you can use frozen zucchini for this recipe. However, I hope it’s already shredded because shredding a thawed frozen zucchini is nearly impossible.

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!

    Parents can make this for their children!

  8. 5 stars
    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.

    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. 🙂
