Bake the cake layers according to the recipe (I recommend using pre-cut parchment rounds for easy removal). Allow the cake layers to cool at room temperature until they are completely cooled.
Remove the cake layers from their pans and peel of the parchment sheets. Wrap each separately in plastic wrap (use press n seal for the best outcome). If you are planning on using them within a week or two, this is enough. If you want to freeze them for an extended period of time, wrap them again tightly in plastic wrap or in foil.
Place them in the freezer until use! Thirty minutes prior to frosting them, remove from the freezer and let defrost slightly.
