Frost your Whiskey Cake with this delicious, rich frosting.
In a medium bowl, cream butter with powdered sugar until light and fluffy. Add remaining ingredients: vanilla, whiskey, chopped pecans. Beat until the frosting is of spreadable consistency. If it seems resistant to "spreading" add a little bit of milk.
