Meringue Frosting is made by whipping egg whites and sugar together to create a light and fluffy frosting. The meringue frosting is used to frost cakes and cupcakes but is also used as a piping to decorate desserts. A pastry bag is used with a star, fluted, or plain nozzle to create rosettes, strips of piping, nests, and other decorative designs on cakes, cupcakes, and many other types of desserts. Meringue frosting can also be added to pies and tarts and then cooked in a hot oven for a short period of time to give it a browned, crisp outer surface with a soft fluffy inside.
