This is an amazing fluffy, delicious frosting. It pipes out beautifully, and holds it's shape. The flavor tastes like marshmallow whipped cream. Be sure to whip the hot sugar syrup with the egg whites for a considerable amount of time, about 8-10 minutes (on a Kitchenaid stand mixer) for the best results. I'm sure this would be excellent on any flavor of cake, but it is fabulous on chocolate cake and probably be great on red velvet.
