2 sticks (1 cup, 8 ounces) unsalted butter, at room temperature
2 (8-ounce) packages cream cheese, at room temperature
2 cups confectioners’ sugar
2 tablespoons milk, more as needed
Directions
Using an electric mixer, whip the butter and cream cheese together until light and fluffy. Beat in sugar, milk and vanilla. If the frosting seems too thick to spread, add a little more milk.
