*To make ahead: Cake layers can be baked ahead, cooled, and stored in the fridge, undecorated, for up to 3 days. You can also freeze the layers for up to a month. Be sure to wrap them tightly in plastic wrap or place in a secure ziptop bag. I recommend storing the layers separate so they do not stick together.
*To store: Decorated cake will store well, covered, at room temperature for up to 3 days, the fridge for 5, and the freezer for a 3 months.
