Easy Decorative Icing
Sifted icing sugar
Place all ingredients in a large mixing bowl. Beat at low speed until ingredients are combined. Then, beat at high speed until stiff glossy peaks form when beaters are lifted, about 5 to 7 minutes. Icing is best used right away, but can be covered with plastic wrap or a damp cloth and kept at room temperature for 2 to 3 hours.
