Ingredients
For the Brownies
2 cups all-purpose flour
½ cup unsweetened cocoa powder
1½ teaspoons baking soda
½ teaspoon salt
½ cup vegetable oil
1½ cups granulated sugar
2 teaspoons vanilla extract
2 cups finely shredded zucchini (do not squeeze dry)
¼ cup milk (only if batter is too thick)

2 tablespoons milk

How to Make Zucchini Brownies
Step 1: Prepare the Oven
Preheat oven to 350°F (175°C).
Grease or line a 9x13-inch baking pan with parchment paper.
Step 2: Mix the Dry Ingredients
In a medium bowl whisk together:
Flour, Cocoa powder, Baking soda, and Salt.
Set aside.
Step 3: Mix the Wet Ingredients
In a large mixing bowl combine:
Vegetable oil, Sugar, and Vanilla.
Stir until smooth.
Fold in the shredded zucchini.
If the batter seems extremely dry after adding the zucchini, let it sit for 5 minutes. The zucchini will naturally release moisture. Add the milk only if needed.
Step 4: Combine
Gradually mix the dry ingredients into the wet ingredients until just combined.
Fold in the chocolate chips.
The batter will be thick.
Step 5: Bake
Spread evenly into the prepared baking pan.
Bake for 28–35 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
Do not overbake.
Allow brownies to cool completely.
Make the Chocolate Frosting
Beat together:
Butter, Cocoa powder, Powdered sugar, Vanilla, Salt, and Milk until smooth and creamy.
Spread over the cooled brownies.
Tips for the Best Zucchini Brownies

Finely shred the zucchini so it melts into the batter.
Don't squeeze out the zucchini moisture—it keeps the brownies soft and fudgy.
Add chopped walnuts or pecans for extra crunch.
Sprinkle extra chocolate chips on top before baking.
Let the brownies cool completely before frosting.
Variations
Add peanut butter chips
Mix in chopped pecans
Add espresso powder to enhance the chocolate flavor
Top with cream cheese frosting instead of chocolate frosting
Use dark chocolate chips for a richer flavor

Frequently Asked Questions
Can you taste the zucchini?
No. The zucchini adds moisture without affecting the chocolate flavor.
Should I peel the zucchini?
No. The peel softens during baking and blends into the brownies.
Can I freeze zucchini brownies?
Yes. Wrap individual brownies tightly and freeze for up to 3 months.
Why are my brownies dry?
They were likely overbaked or the zucchini didn't contain enough moisture. Bake just until a toothpick comes out with a few moist crumbs.
