Description

These ultra-moist and fudgy chocolate zucchini brownies are the perfect guilt-free indulgence. Packed with hidden veggies, rich cocoa flavor, and a silky frosting, they’re a delicious way to sneak more nutrition into dessert time.

Ingredients

Scale
  • 1/2 cup vegetable oil
  • 1 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 teaspoons vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 cups shredded zucchini (about 2 medium zucchini)
  • Optional: 1/2 cup chocolate chips
  • Optional: 1/2 cup chopped walnuts
  • For the Frosting:
  • 1/4 cup melted butter
  • 1/4 cup unsweetened cocoa powder
  • 2 cups powdered sugar
  • 1/4 cup heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C) and line a 13×9-inch baking dish with parchment paper.
  2. In a large bowl, whisk together vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth.
  3. Add flour, cocoa powder, baking soda, and salt. Stir until just combined. Batter will be dry.
  4. Fold in shredded zucchini. Let batter rest for 10 minutes to allow moisture release. Fold in chocolate chips or walnuts if using.
  5. Pour into prepared pan, smooth the top, and bake for 25–30 minutes until a toothpick comes out with moist crumbs.
  6. Cool completely in pan before frosting.
  7. For the frosting, whisk melted butter and cocoa powder in a bowl. Add powdered sugar, heavy cream, and vanilla. Mix until smooth.
  8. Spread frosting evenly over cooled brownies. Slice with a plastic knife for clean cuts.

Notes

Let the batter rest after adding zucchini to avoid dry texture. Do not overbake. Use parchment for easy removal and cleaner edges.
