1 1-pound, 3.8-ounce fudge brownie mix (a box that makes a 9x13-inch pan of brownies)
1/2 cup oil
1/4 cup Baileys Irish Crème Liquor
1/2 cup butter or margarine (softened)
2 cups powdered sugar
2 Tablespoons Baileys Irish Crème Liquor
1/2 teaspoon vanilla
2 to 3 teaspoons milk
Food coloring, optional
Heat oven to 350 degrees. Grease and flour the bottom and sides of a 9x13-inch baking pan.
In a large bowl combine the brownie mix, oil, 1/4 cup Baileys Irish Crème and eggs. Mix well. Spread into prepared pan. Bake for 24 to 30 minutes. Do not overbake or the brownies will start to harden and stick to the pan. Set aside and let cool for at least 45 minutes.
For the frosting: Beat the 1/2 cup butter until light and fluffy. Add the powdered sugar, 2 tablespoons Baileys Irish Crème, vanilla and one teaspoon of milk. Mix well. If necessary, add additional milk to get the frosting to a consistency that it is easy to spread. If making the brownies for a holiday event (such as Easter) add food coloring. Spread the frosting on the cooled brownies. Cut, serve and enjoy!
