Buttercream Frosting

1 stick butter at room temperature
3 cups powder sugar
3 to 4 tablespoons milk
1 teaspoon of vanilla

1. Place the butter in a large mixing bowl. Blend until fluffy, 30 seconds. After that add the powder sugar, milk and vanilla. Blend with the mixer on low speed until the sugar is incorporated, 1 minute. Increase the speed to medium and beat until light and fluffy, 1 minute more. Add up to 1 tablespoon more milk if the frosting seems to stiff.

This frosting was so light and fluffy.
