Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 2 cups zucchini, shredded using the large hole side of a grater (do not tightly pack)

• 1 large egg

• 1/2 cup coconut oil, melted

• 1/2 cup maple syrup, honey, or other liquid sweetener

• 1 teaspoon pure vanilla extract

• 1/2 cup cacao or cocoa powder

• 1/2 teaspoon baking soda

• 1/4 teaspoon salt

• 1 cup whole wheat or spelt flour

Directions

1. Place shredded zucchini in a colander and let it sit while you prepare the other ingredients.

2. Preheat your oven to 375°F and line an 8×8-inch glass baking dish with parchment paper.

3. In a large bowl, whisk together the egg, melted coconut oil, maple syrup, and vanilla extract.

4. Add cacao powder, baking soda, and salt. Whisk again until fully combined.

5. Give the zucchini a gentle squeeze—don’t wring it out completely—and stir it into the batter.

6. Add the flour and mix gently until just combined.

7. Pour the batter into the prepared baking dish and level it with a spatula.

8. Bake for 25–28 minutes. The center should be just slightly jiggly and a toothpick inserted should come out with some moist crumbs. Avoid overbaking.

9. Let the brownies cool in the pan for 1 hour. Then lift them out using the parchment paper and transfer to a cooling rack to cool completely.

10. Cut into 16 squares and enjoy!

FAQs

Do I need to peel the zucchini?

No, leave the skin on. It adds nutrients and blends right into the batter without affecting taste or texture.

Should I squeeze all the water out of the zucchini?

No, just give it a gentle squeeze. You want to retain some moisture for that fudgy texture.

Can I use all-purpose flour instead of whole wheat or spelt?

No, the texture may change. This recipe is specifically tested with whole wheat or spelt flour.

Can I make these brownies gluten-free?

Unfortunately, no. Gluten-free flours don’t provide the same structure needed for this recipe.

Are these brownies very sweet?

They are mildly sweet. For a sweeter version, increase the maple syrup to 3/4 cup or add chocolate chips.

What’s the difference between cacao and cocoa powder?

Cacao is less processed and slightly more bitter. Cocoa powder is more common and perfectly fine to use here.

Can I substitute the coconut oil?

Yes, use any mild-tasting oil like avocado or vegetable oil. Keep in mind coconut oil adds a firmer texture once cooled.

Can I add frosting to these brownies?

Yes! A healthy chocolate or cream cheese frosting would be a great addition.

How do I make them more cakey instead of fudgy?

Use a metal baking pan instead of glass and bake slightly longer.

Do these brownies taste like zucchini?

Not at all! The zucchini melts into the batter and is completely undetectable in flavor.
