Creating Irish Mint Brownies involves these simple steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. Make the Brownie Batter: In a medium saucepan, melt the unsalted butter over low heat. Once melted, remove from heat and stir in the granulated sugar, eggs, and vanilla extract until well combined.
3. Add Dry Ingredients: Sift together the flour, cocoa powder, salt, and baking powder. Gradually fold this mixture into the wet ingredients until smooth. Do not overmix.
4. Pour the Brownie Batter: Spread the brownie batter evenly in the prepared baking pan, and bake for 30-35 minutes. A toothpick should come out with just a few moist crumbs when done.
5. Cool the Brownies: Allow the brownies to cool in the pan on a wire rack for about 1 hour. This step is essential for achieving the perfect texture.
6. Prepare the Mint Layer: In a large bowl, beat the softened butter until creamy. Gradually add in the powdered sugar, followed by the milk, peppermint extract, and food coloring. Mix until smooth and fluffy.
7. Spread the Mint Layer: Once the brownie layer has cooled, spread the mint mixture evenly over the brownies using a spatula.
8. Make the Chocolate Topping: In a microwave-safe bowl, combine the chocolate chips and 2 tablespoons of butter. Microwave in 30-second intervals until melted, stirring each time until smooth.
9. Top with Chocolate: Pour the melted chocolate over the mint layer and spread it evenly.
10. Chill and Cut: Refrigerate the brownies for at least 1-2 hours until the chocolate topping is firm. Once set, cut them into squares for serving.
