Unfiled
1 pound powdered sugar
1/4 cup Kahlua
3 tablespoons shortening
3 tablespoons butter, softened
2 teaspoons light corn syrup
food coloring
In a large bowl mix all ingredients, except for food coloring, until smooth. If you want to use different colors for your decorating, divide the frosting and tint each portion with food coloring, as desired. Decorate cookies using a pastry bag and decorators tips.
If you want a spreadable frosting, use an additional 1 to 2 tablespoons of Kahlua in the recipe.
