How to Make Frosted Zucchini Brownies

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, combine 2 cups grated zucchini, 1 ½ cups granulated sugar, 1 teaspoon vanilla extract, and ½ cup vegetable oil. Mix well.
  3. In a separate bowl, whisk together 1 ¾ cups all-purpose flour, ¾ cup unsweetened cocoa powder, 1 teaspoon baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  5. Pour batter into the prepared pan and bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs.
  6. Let the brownies cool completely in the pan before frosting.
  7. **For the frosting:** In a medium saucepan over medium heat, melt 6 tablespoons (3 ounces) unsalted butter.
  8. Stir in 2 cups powdered sugar and ½ cup milk. Bring to a boil, stirring constantly.
  9. Boil for 1 minute, stirring continuously. Remove from heat.
  10. Stir in 1 cup semi-sweet chocolate chips and ½ cup mini marshmallows until melted and smooth.
  11. Stir in 1 teaspoon vanilla extract.
  12. Spread the frosting evenly over the cooled brownies.
  13. Sprinkle with ½ cup chopped walnuts, if desired.
