- You can prepare the cake layers ahead of time and freeze them; they keep their freshness when thawed. The frosting can also be made in advance and stored in the refrigerator for up to a month — just stir it well after thawing for the best texture. For assembling, chilling the cake layers makes stacking and frosting much easier and helps prevent sliding. If the layers do slide, inserting a dowel or chopstick through the center adds stability. Leftover frosting can be refrigerated and used to keep cut cake moist. Store the finished cake in the fridge for up to a week if no fresh fruit is added.
