Allow the cake to cool completely. Use plastic wrap or aluminum foil to wrap the cake tightly. Or, place it in an airtight container. Store in a cool, dry place for up to 5-6 days. Freezing: Once wrapped, place the cake in a freezer-safe container or bag. The cake can be stored in the freezer for up to 2-3 months. Thawing and serving: When you're ready to enjoy the cake, remove it from the freezer and let it thaw in the refrigerator for several hours or overnight. Once thawed, you can bring it to room temperature before serving.
