Ingredients

Scale

For the brownie layer:

  • 1 cup unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder
  • ½ teaspoon salt

For the mint layer:

  • ½ cup unsalted butter, softened
  • 2 cups powdered sugar
  • 2 tablespoons milk
  • 1 teaspoon peppermint extract
  • Green food coloring (optional)

For the chocolate topping:

  • 1 cup semi-sweet chocolate chips
  • ½ cup unsalted butter

Instructions

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.

In a large bowl, whisk together melted butter and sugar. Add eggs and vanilla, mixing until smooth.

Sift in flour, cocoa powder, and salt. Stir until fully combined.

Pour the batter into the prepared pan and spread evenly. Bake for 25–30 minutes, or until a toothpick inserted comes out with moist crumbs. Let cool completely.

For the mint layer, beat softened butter until creamy. Add powdered sugar, milk, peppermint extract, and food coloring if using. Beat until light and fluffy.

Spread the mint mixture evenly over the cooled brownies. Place in the refrigerator to chill for 30 minutes.

For the chocolate topping, melt chocolate chips and butter together until smooth. Let it cool slightly, then pour over the mint layer and spread evenly.

Refrigerate until the chocolate is set. Slice and serve.

Notes

  • For clean layers, chill brownies between each step.

  • Use high-quality cocoa and chocolate for best results.

  • Adjust peppermint extract to your taste—start with less and build up.

  • Optional: Add crushed mint candies or chocolate chips for texture.

  • Best served chilled or at room temperature with coffee or hot chocolate.
