Ingredients

Brownie Batter

  • 1 cup butter (melted and slightly cooled)
  • 1/2 cup unsweetened natural cocoa powder
  • 2 tablespoons honey
  • 4 eggs
  • 2 cups granulated sugar
  • 1 3/4 cups all purpose flour
  • 1/2 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1 cup chopped walnuts or pecans (optional)

Mint Icing

  • 5 tablespoons butter (softened to room temperature)
  • 4 tablespoons milk
  • 1 tablespoon light corn syrup
  • 2 1/3 cups powdered sugar (sifted to remove lumps)
  • 1/2 teaspoon mint extract
  • 23 drops green food coloring

Chocolate Frosting

  • 5 tablespoons butter (softened to room temperature)
  • 4 tablespoons milk
  • 1 tablespoon light corn syrup
  • 2 1/3 cups powdered sugar (sifted to remove lumps)
  • 1/3 cup cocoa powder (sifted)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan with cooking spray or butter to prevent sticking.
  2. Prepare for Mixing: Use a hand mixer or stand mixer with paddle attachment for easier mixing. A whisk can be used but note that the batter will be thick and more difficult to combine well.
  3. Make the Brownie Batter: In a large mixing bowl, combine the melted butter and cocoa powder until smooth and well incorporated. Add the honey and eggs, mixing until fully combined. Gradually add the granulated sugar, all-purpose flour, baking powder, and salt. Mix thoroughly. Fold in the chopped nuts if you choose to use them. Pour the batter evenly into the prepared pan.
  4. Bake the Brownies: Place the pan in the preheated oven and bake for 25 to 27 minutes. Check doneness by inserting a toothpick; it should come out with moist crumbs but not wet batter. Remove from oven and allow to cool completely before icing.
  5. Prepare Mint Icing: In a clean bowl, beat together the softened butter, milk, light corn syrup, and powdered sugar until the mixture is smooth and fluffy. Add the mint extract and green food coloring, mixing until evenly combined. Adjust thickness by adding milk gradually until the icing consistency is slightly thinner than typical cake frosting.
  6. Apply Mint Icing and Freeze: Spread the mint icing evenly over the completely cooled brownies. Place the iced brownies in the freezer for 30 minutes or until the icing is firm enough to hold the next layer without mixing.
  7. Prepare Chocolate Frosting: Beat together the butter, milk, corn syrup, cocoa powder, and powdered sugar until smooth and fluffy. If necessary, add additional milk one teaspoon at a time to reach a consistency slightly thinner than cake frosting to make spreading easier.
  8. Finish with Chocolate Frosting: Remove the brownies from the freezer. Spread the prepared chocolate frosting over the firm mint icing layer. Allow the frosting to set before slicing and serving.

Notes

  • Using a mixer with a paddle attachment makes mixing thick brownie batter much easier.
  • Sifting powdered sugar and cocoa powder before adding to frostings removes lumps, resulting in smoother icing.
  • Freezing the brownies after applying the mint icing prevents the chocolate frosting from blending into the mint layer, allowing distinct layers.
  • Chopped nuts are optional; walnuts or pecans both work well for added texture.
  • Mint extract and green food coloring are crucial for the classic mint flavor and appearance.
  • Ensure brownies are completely cooled before adding the mint icing to prevent melting.
