Brownies:
2 boxes brownie mix and all ingredients for brownies (cake-like style with extra eggs)
Peppermint Frosting:
4 cups powdered sugar
1 cup butter, softened
4 drop green food coloring
1 1/2 teaspoons peppermint extract
2 tablespoons water
Chocolate Ganache:
12 oz. semisweet chocolate chips
3/4 cup butter
1 or 2 teaspoons peppermint extract
To make the brownies: Follow the recipe for cake-like brownies. Or if there isn't one, add 3 more eggs total. Pour into a large, greased cookie/jelly roll sheet, bake and let cool completely.
To make the mint frosting: Combine powdered sugar, butter, water, peppermint extract and food coloring. Mix. Spread over cooled brownies and refrigerate until hard on top.
To make chocolate ganache: Microwave chocolate chips and butter for 2 minutes. Stir until all chocolate chips are melted and the mixture is smooth. Add 2 tsp. peppermint extract. As soon as this mixture thickens and is no longer hot, spread over mint topping on brownies. Put back into the refrigerator until hard.
