Instructions
Preheat oven to 350 degrees. Start by placing parchment paper in an 8-inch or 9-inch baking pan and press into the sides. If you don't have parchment paper, you can just lightly spray the baking pan with non-stick cooking spray.
Make the brownie batter according to the package instructions or if you are using my homemade brownie recipe, make a batch. If you want a thinner brownie layer, you can 1/2 the recipe.
Pour the brownie batter into the pan and bake for about 25-30 minutes (this time will vary depending on whether you use an 8-inch or 9-inch baking pan) or until a toothpick comes out clean. These brownies may be slightly ooey gooey but should be baked enough that they will set up when cooled. Let the brownies cool completely.
Make the mint cream layer by whipping the butter, powdered sugar, milk, and mint extract together until light and fluffy. Since mint extract has a very strong flavor, start with just a small amount and you can always add more. Stir in the green food coloring.
Make the chocolate layer by melting in the microwave the butter and chocolate chips at 50% power in 45-second increments until the chocolate and butter are melted. Stir until smooth.
Once the brownies have cooled, frost them with the mint frosting, and then pour on the chocolate mixture. Let set up at room temperature or you may cover it and chill it in the refrigerator.
If you used parchment paper, carefully lift up the sides and remove the brownies from the pan to cut them into small squares. For extra smooth cuts, I suggest using a sharp knife dipped in hot water and wiped off with a paper towel.
Oil -- this helps to make the brownies super moist. You can use any type of oil from canola to vegetable to olive oil.
Butter -- this is the base for the mint frosting layer. You can use salted or unsalted butter in this recipe. If you use unsalted butter, add a pinch of salt to balance the sweetness.
Peppermint Extract -- I suggest using a good quality peppermint extract and starting off with just a small amount. I prefer to use the Nielsen-Massey Peppermint Extract.
Chocolate Chips -- this is for the decadent chocolate layer on top of the mint cream frosting. I would suggest using semi-sweet chocolate but you can also use dark chocolate or milk chocolate. My favorite chocolate is Ghirardelli, Guittard, and Callebaut.
Butter -- this is to be melted with the chocolate to create the perfect chocolate layer.
