Yes, it is common for people to put their leftover wedding cakes in the freezer. Preserving the top tier of the wedding cake has been a long-standing tradition in many cultures. The frozen cake is typically enjoyed on the couple's first wedding anniversary or another significant occasion.
To preserve the cake, it is essential to wrap it properly before placing it in the freezer. Typically, the cake is initially chilled in the refrigerator to firm it up. Then it is covered with plastic wrap to protect it from freezer burn and additional layers of aluminum foil to ensure it stays well insulated. Some couples also opt to place the wrapped cake in an airtight container or a freezer bag for extra protection.
Properly stored, a wedding cake can generally remain in the freezer for up to a year without significant loss in quality. However, it's worth noting that the texture and taste of the cake may change slightly after being frozen for an extended period. To maintain the best possible taste and texture, it's recommended to consume the frozen cake within a few months of freezing it.
It's also worth mentioning that not all couples choose to freeze their wedding cake. Some prefer to enjoy all of it on their wedding day or share the leftovers with family, friends, or charitable organizations.
