An anniversary cake
is a small cake, to be enjoyed on the anniversary of a wedding.
The top tier of the actual wedding cake is often set aside on the wedding day, and frozen, to be used for the first of many wedding anniversary cakes. If you plan to freeze the top layer of your wedding cake, it should be carefully wrapped in an airtight container, and placed in the freezer for storage.
Of course, if you don't want to go the freezer route (or you get the midnight munchies and eat the cake early... oops!), you may choose to simply re-create the top tier of your wedding cake.

Very early versions of wedding anniversary cakes have existed since the Roman Empire (509 to 27 BC). At this time, anniversary cakes were made from wheat flour, salt, and water. British versions were flat, round cakes, filled with fruit and nuts. In fact, if you are looking for wedding anniversary cakes which freeze well, fruitcakes are one of your best bets. Cheesecakes and basic white cakes with buttercream frosting also do the job just fine.
