These brownies are perfect for summer baking, potlucks, family desserts, lunchbox treats, or whenever you want a soft and fudgy chocolate dessert. Even people who are unsure about baking with zucchini may be surprised by how tender and flavorful these brownies are.
Why Make Brownies with Zucchini?
- Zucchini keeps brownies moist. Shredded zucchini adds natural moisture to the batter, helping the brownies stay soft and tender.
- You cannot taste the zucchini. Once baked with cocoa, vanilla, sugar, and chocolate chips, the zucchini disappears into the brownies.
- It is a great way to use garden zucchini. If you have extra zucchini on hand, this recipe turns it into a chocolate dessert everyone can enjoy.
- The texture is fudgy and satisfying. These cocoa zucchini brownies are dense enough to feel rich but still soft enough to melt in your mouth.
- Chocolate cravings are covered. Cocoa powder, mini chocolate chips, and fudge frosting make this recipe a true chocolate lover’s dessert.

How to Make Zucchini Brownies
Fudgy Cocoa Zucchini Brownies
- Preheat the oven to 350 degrees. Line a 9×13-inch pan with aluminum foil or parchment paper, then lightly spray it with cooking spray for easy removal.
- In a medium bowl, combine the oil, eggs, vanilla extract, and granulated sugar. Beat with a mixer for 2 minutes, or until the mixture is well blended.
- In a separate bowl, whisk together the flour, cocoa powder, and baking soda.
- Add the wet mixture to the dry ingredients and mix until combined.
- Stir in the shredded zucchini until it is evenly distributed throughout the batter.
- Fold in the mini chocolate chips.
- Spread the brownie batter evenly into the prepared 9×13-inch pan.
- Bake for 20 to 25 minutes, or until the brownies are set. Allow them to cool completely before frosting.
Chocolate Fudge Frosting
- Using a mixer, cream the softened butter until smooth.
- Add the confectioners’ sugar and beat until light and fluffy.
- Beat in the cocoa powder.
- Add the milk or heavy cream gradually and continue mixing until the frosting reaches a smooth, spreadable consistency.
- Spread the frosting over the cooled brownies, then cut into squares and serve.
Zucchini Tip
- You will need 1 1/2 cups of grated zucchini. This is about 1 medium-large zucchini or 2 small-medium zucchini. If your zucchini is very watery, gently squeeze out some excess moisture before adding it to the batter.
Serving & Storing Zucchini Brownies
- Serving: These fudgy zucchini brownies are best served at room temperature. Let the frosting set slightly before slicing for cleaner squares.
- Storing: Keep brownies fresh in a sealed container or zip-top bag. Once cooled to room temperature, they can be stored in the refrigerator for up to 3 days or frozen tightly wrapped for up to 3 months.
