You can freeze angel food cake successfully for up to four months if you wrap the un frosted sponge tightly in plastic wrap and aluminum foil. The delicate, airy texture of angel food cake holds up remarkably well in the freezer without losing its signature softness. Thaw the wrapped cake overnight in the refrigerator before unwrapping and serving it with fresh berries or glaze. Avoid freezing frosted angel food cake because the whipped toppings can separate and become soggy.
