- 1 cup (2 sticks) unsalted butter, softened
- 2 tablespoons vanilla extract
- 1/2 cup milk
- 2 16-ounce boxes confectioners sugar
- pinch of salt
In a bowl, beat butter until fluffy. Beat in vanilla and milk. Gradually add in sugar until you reach desired consistency.
You can make this up to one week before you use it. Cover and refrigerate and, on the day you use it, bring to room temp and rebeat for smooth consistency. Makes enough for 2 9-inch cakes or 1 sheet cake.
