Probably the best buttercream frosting I've had.
Vanilla Buttercream Frosting
1 cup butter, softened
3 1/2 cups confectioners' sugar
1 teaspoon milk
1 teaspoon vanilla extract
1/8 teaspoon salt (if using salted butter only add a pinch)
1. In a bowl combine butter, sugar and salt. Beat till blended.
2. Add the milk and vanilla and beat for an additional 3 to 5 minutes or until smooth and creamy.
