1/4 cup butter (NO SUBSTITUTES!)
3 TBSP buttermilk
2 1/4 cups Domino's powdered sugar
2 tsp. vanilla
In a saucepan over low heat add butter and buttermilk--cook/stir until melted and smooth, then cook/stir until mixture comes to a boil. As soon as mixture comes to a boil, remove from heat--add vanilla--stir quickly. Pour hot mixture into a mixer--slowly add powdered sugar--beat until mixed, then beat on high speed for 4 minutes. Cool to room temperature, then beat again. If too thick for spreading, add a little milk and beat again. If too thin, add a little more powdered sugar and beat again.
