Ingredients

Brownie Batter

  • 1 cup oil (avocado, vegetable, or canola oil)
  • 2 cups granulated sugar
  • 4 large eggs
  • 6 Tablespoons unsweetened cocoa powder
  • 1 teaspoon salt
  • 1 1/2 cups all-purpose flour
  • 1 Tablespoon vanilla extract

Mint Frosting

  • 2 cups powdered sugar
  • 4 Tablespoons butter, room temperature
  • 1 1/2 teaspoons peppermint extract
  • 1-2 Tablespoons milk
  • Green food coloring (optional)

Chocolate Frosting

  • 1/2 cup melted butter
  • 2/3 cup unsweetened cocoa powder
  • 3 cups powdered sugar
  • 1/3 cup milk
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven: Preheat your oven to 350 degrees Fahrenheit to prepare for baking the brownies.
  2. Prepare batter: In a mixing bowl, combine the sugar and oil. Add eggs one at a time, ensuring each is mixed well before adding the next. Stir in the vanilla extract. Gradually add the dry ingredients — unsweetened cocoa powder, salt, and all-purpose flour — and mix until just combined.
  3. Bake brownies: Grease a 9×13-inch baking pan. Pour the batter into the pan and spread it evenly. Bake in the preheated oven for 30 minutes or until a toothpick inserted into the center comes out clean. Allow the brownies to cool completely before adding frosting.
  4. Make mint frosting: In a separate bowl, beat together powdered sugar, softened butter, peppermint extract, and 1 to 2 tablespoons of milk until the mixture is light and fluffy. Add green food coloring if desired to enhance the minty appearance. Spread the mint frosting evenly over the cooled brownies. Refrigerate to set while preparing the chocolate frosting.
  5. Prepare chocolate frosting: Combine melted butter and cocoa powder in a bowl. Gradually add powdered sugar, milk, and vanilla extract. Mix thoroughly for several minutes until the frosting is smooth and fluffy.
  6. Frost brownies: Spread the chocolate frosting over the mint layer on the brownies evenly. Allow to set before slicing and serving.

Notes

  • Make sure brownies are completely cooled before frosting to prevent melting.
  • Adjust the milk in frostings to achieve preferred consistency.
  • Use green food coloring sparingly to get the desired minty color.
  • Store brownies refrigerated if not served immediately to keep frostings firm.
  • For a stronger mint flavor, increase peppermint extract slightly but don't overdo to avoid bitterness.
