how can you decorate a cake to be frozen
1 When freezing a cake, be sure that it is completely cooled before wrapping. 2  Wrap the cake tightly in plastic wrap and then wrap it again in foil before placing it in the freezer. 3  If you do not have time to freeze the cake overnight, freezing it for 2 or 3 hours will help when it comes time to decorate it. Place the frosted cake on a solid flat surface that can be used to hold the cake when placed in the freezer, such as a cookie sheet, cake board, or cutting board. 2  Place the unwrapped cake in the freezer. 3  Freeze unwrapped until the frosting and decorations are frozen hard.
