Method
 

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan, or line it with parchment paper, leaving an overhang on the sides for easy removal.
    In a large bowl, whisk together the melted butter and granulated sugar until well combined. Beat in the eggs one at a time, until each is fully incorporated. Stir in the vanilla extract and the ½ teaspoon of peppermint extract.

  2. In a separate medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to dry brownies.
    1 cup all-purpose flour, ½ cup unsweetened cocoa powder, 1 teaspoon baking powder, ½ teaspoon salt
  3. Gently fold in the 1 cup of semi-sweet chocolate chips into the batter. If you desire an even more chocolatey brownie, you can stir in an extra handful of chocolate chips here.

  4. Pour the batter evenly into the prepared baking pan. Spread it out with a spatula to ensure an even layer. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached, but not wet batter. Be careful not to overbake, as this will dry out your brownies.
  5. While the brownies are cooling, prepare the mint frosting. In a medium bowl, beat the softened butter with an electric mixer until smooth and creamy. Gradually add the sifted powdered sugar, alternating with the milk or heavy cream, beating until smooth and fluffy. Stir in the vanilla extract and peppermint extract. If you'd like a pop of color, add a few drops of green food coloring and mix until evenly distributed.

  6. Once the brownies are fully cooled, prepare the chocolate ganache. Place the finely chopped chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges. Pour the hot cream over the chopped chocolate and let it sit for 5 minutes to allow the chocolate to melt. Gently whisk the mixture until smooth and glossy.

  7. Once the brownies have completely cooled and the ganache is ready, spread the mint frosting evenly over the top of the cooled brownies. Drizzle the chocolate ganache over the mint frosting. You can use a spoon or a piping bag for this. For a marbled effect, gently swirl the ganache into the frosting with a toothpick or knife.
  8. Place the pan of Ultimate Mint Brownies in the refrigerator for at least 30 minutes to allow the frosting and ganache to set before cutting. This step is crucial for clean cuts and a delicious, firm texture.
