Fondant Marshmallow Icing recipe (for birthday cake). Do not refrigerate your covered cake! When you take the cake out of the refrigerator, moisture will condense and destroy your beautiful surface. Your best option is to store the cake in a sealed bakery box. The cardboard sides of a box will keep the dust in the air off the cake, but allows the Fondant to breath.
Best Ever Buttercream Frosting | Before you begin covering your cake with fondant, be sure that your cake is covered with a layer of buttercream at least 1/4-inch thick. This frosting layer helps the fondant stick to the cake and smooths out any bumps or imperfections on the cake surface, so the fondant layer looks clean and smooth. And it's buttercream, so it tastes amazing, right?
