Description

This Chocolate Zucchini Brownies Recipe creates rich, fudgy brownies with a moist texture thanks to fresh zucchini. Topped with creamy dark chocolate frosting, they’re perfect for any occasion—from casual snacks to special gatherings.


Ingredients

Scale

For the Brownies:

½ cup vegetable oil

1 cup granulated sugar

½ cup packed light brown sugar

2 teaspoons pure vanilla extract

2 cups all-purpose flour

½ cup dark chocolate unsweetened cocoa powder

1 ½ teaspoons baking soda

1 teaspoon kosher salt

2 ½ cups finely shredded zucchini

For the Frosting:

¼ cup unsalted butter, melted

5 tablespoons dark chocolate unsweetened cocoa powder

2 cups powdered sugar

6 tablespoons heavy whipping cream

½ teaspoon vanilla extract


Instructions

  • Prep the Pan – Preheat oven to 350°F (175°C). Line a 13×9-inch baking dish with parchment paper, leaving an overhang for easy removal.

  • Mix the Wet Ingredients – In a large mixing bowl, whisk together vegetable oil, granulated sugar, light brown sugar, and vanilla until smooth.

  • Add Dry Ingredients – Stir in the flour, cocoa powder, baking soda, and salt. The batter will appear very dry at this stage—don’t worry!

  • Incorporate Zucchini – Fold in shredded zucchini. Should the batter seem dry, let it rest for 10 minutes to allow the zucchini to naturally release its moisture.

  • Bake the Brownies – Pour the batter evenly into the prepared pan and bake for 25–30 minutes, or until a toothpick inserted in the center emerges with just a few moist crumbs.

  • Cool Completely – Allow brownies to cool fully before frosting to avoid melting the topping.

  • Make the Frosting – Prepare the frosting by whisking melted butter and cocoa powder together in a medium bowl until silky smooth. Gradually add powdered sugar, alternating with heavy cream, whisking until fluffy. Stir in vanilla.

  • Frost & Serve – Once cooled, generously frost the brownies, cut into squares, and savor each indulgent bite.

Notes

Resting the batter before baking helps zucchini moisture hydrate the batter.

A plastic knife cuts brownies cleanly without crumbling.

Store at room temperature up to 4–5 days, refrigerate up to 1 week, or freeze up to 3 months.
