Description

These extra fudgy chocolate zucchini brownies are rich, moist, and packed with chocolate flavor. The zucchini keeps them soft without being detectable, and the creamy frosting makes them indulgent and satisfying.


Ingredients

  • 1 1/2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup granulated sugar
  • 1/2 cup brown sugar
  • 1/2 cup vegetable oil or melted butter
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • 2 cups shredded zucchini (excess moisture squeezed out)
  • 1 cup semi-sweet chocolate chips

For the creamy frosting:

  • 1/2 cup butter, softened
  • 2 cups powdered sugar
  • 1/4 cup unsweetened cocoa powder
  • 23 tablespoons milk or heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9x13-inch baking pan.
  2. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
  3. In a large bowl, beat together granulated sugar, brown sugar, oil (or melted butter), vanilla, and eggs until smooth.
  4. Stir dry ingredients into wet mixture just until combined.
  5. Fold in shredded zucchini and chocolate chips. Batter will be thick.
  6. Spread batter evenly into prepared pan and bake for 30–35 minutes, or until a toothpick inserted comes out with moist crumbs.
  7. Cool brownies completely before frosting.
  8. For frosting: Beat butter, powdered sugar, cocoa powder, vanilla, and milk until smooth and spreadable.
  9. Frost cooled brownies evenly, allow to set, then slice and serve.

Notes

  • Squeeze excess moisture from zucchini to avoid soggy brownies.
  • You can substitute dark chocolate chips or add nuts for variety.
  • For a gluten-free option, use a 1:1 gluten-free flour blend.
  • Store brownies in an airtight container at room temperature for up to 3 days, refrigerated up to 5 days, or freeze (without frosting) for longer storage.
