Fudge Iced Brownies Recipe


For the brownies:

  • 1 1/2 cups (3 sticks) unsalted butter, softened
  • 2 1/2 cups granulated sugar
  • 4 large eggs
  • 3 teaspoons pure vanilla extract
  • 3 cups all-purpose flour
  • 1 tablespoon unsweetened cocoa powder
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 cup chopped walnuts (optional)

For the fudge icing:

  • 6 tablespoons unsalted butter
  • 3 cups powdered sugar
  • 1/3 cup unsweetened cocoa powder
  • 1/4 cup milk
  • 1 teaspoon pure vanilla extract
  • Pinch of salt


  • Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13 inch baking pan. Line the bottom of the pan with parchment paper, allowing the sides to overhang for easy removal.
  • Make the brownies: In a large bowl, cream together the softened butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract.
  • In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the chopped walnuts, if using.
  • Pour the batter into the prepared baking pan. Spread the batter evenly using a spatula.
  • Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Do not overbake, as the brownies will continue to cook after they are removed from the oven.
  • Make the fudge icing: While the brownies are baking, prepare the icing. In a saucepan, melt the butter over low heat. Remove from heat and whisk in the powdered sugar, cocoa powder, milk, vanilla extract, and salt until smooth and shiny.
  • Let the brownies cool completely in the pan on a wire rack before frosting. Once cool, spread the fudge icing evenly over the top of the brownies.
  • Allow the icing to set for at least 30 minutes before cutting the brownies into squares.


  • For chewier brownies, bake for 25 minutes. For fudgier brownies, bake for 30 minutes.
  • If you don’t have chopped walnuts, you can substitute another chopped nut of your choice, or leave them out altogether.
  • To make the brownies extra decadent, sprinkle some sea salt over the top of the icing before it sets.
  • Brownies can be stored at room temperature for up to 3 days, or in the refrigerator for up to a week.
