Ingredients
Brownies:
½ cup vegetable oil
1 cup granulated sugar
½ cup packed light brown sugar
2 tsp vanilla extract
2 cups all-purpose flour
½ cup unsweetened dark cocoa powder
1½ tsp baking soda
1 tsp kosher salt
2½ cups finely shredded zucchini
Frosting:
¼ cup unsalted butter, melted
5 tbsp unsweetened cocoa powder
2 cups powdered sugar
6 tbsp heavy whipping cream
½ tsp vanilla extract
Instructions
- Preheat oven to 350°F (175°C) and line a 13×9-inch baking dish with parchment paper; set aside.
- In a large bowl, whisk together the vegetable oil, granulated sugar, light brown sugar, and vanilla until well combined.
- In a separate bowl, mix flour, cocoa powder, baking soda, and salt. Stir flour mixture into the sugar/oil mixture until well blended—the batter will be very dry.
- Gently fold in the shredded zucchini. Depending on its moisture, the batter may still look dry. Let it rest for 10 minutes to allow the zucchini to hydrate and soften the mix.
- Once rested, transfer the batter to your prepared baking dish and spread it out evenly.
- Bake for 25–30 minutes, checking that a toothpick inserted comes out with moist crumbs but no uncooked batter.
- Take the brownies out of the oven and allow them to cool fully before adding frosting.
- To make frosting, whisk melted butter and cocoa together until smooth. Add powdered sugar, heavy cream, and vanilla; whisk until silky. Adjust thickness with a splash more cream if needed.
- Spread frosting evenly over cooled brownies. Slice into bars and enjoy!
Notes
Let the batter sit for 10 minutes—zucchini moisture helps bind the dry mix. Use a plastic knife for clean cuts. Brownies store well covered for up to 5 days at room temp or 3 months in the freezer.
