Cinnamon Roll Icing

I've got a cinnamon roll recipe that I love and the icing is like the Cinnabon frosting and is delicious but sometimes I want something more simple and not as thick and rich.  This one is simple, easy and perfect!

Ingredients 

• 2 cup powdered sugar aka confectioner's sugar
• 2 tablespoon butter melted
• 2 teaspoon vanilla
• 4 tablespoon milk can substitute with heavy cream or half and half

Instructions 

• Combine powdered sugar, melted butter, vanilla and milk in a large mixing bowl until smooth.
• Pour over warm rolls and spread.
