1 box dark chocolate brownie mix
6 tablespoons butter
1 ½ cups powdered sugar
1 ½ tablespoons milk
½ teaspoon peppermint extract
A couple of drops green food coloring
6 tablespoons butter
¾ cup chocolate chips
Prepare the brownie mix as directed in 9 x 13 pan, being careful not to overbake. Set aside to cool.
For the frosting, combine using mixer: butter, powdered sugar, milk, peppermint extract and green food coloring. Beat until fluffy. Spread the frosting on top of the brownies after they have cooled.
For the top layer, melt the butter and chocolate chips slowly in a small saucepan on low heat. Mix until smooth and all the chocolate is melted. Let cool partially before pouring over frosting; gently use the back of a spoon or spatula to spread evenly. Allow chocolate to set before cutting into squares.
