Basic Sweet Buttercream Frosting
1/2 cup unsalted butter, at room temperature
2 cups sifted powdered sugar
2 tablespoons milk
1 teaspoon vanilla
Beat butter until creamy, about 30 seconds. Add powdered sugar, milk and vanilla, and beat on high until light and fluffy, about 5 minutes.
Note: To make the frosting chocolate, substitute 1/4 cup cocoa powder for 1/4 cup of the sugar.
Yields enough to frost 12 cupcakes generously. Leftover frosting will keep for up to a week in the refrigerator.
