The tradition of serving a wedding cake at your reception dates back a long time. The cake is usually on display as a centerpiece of the wedding. Traditionally, wedding cakes were made to bring good luck to all guests and the couple. Some cakes are built with only a single edible tier for the bride and groom to share. Wedding cakes come in a variety of sizes, depending on the number of guests the cake will serve. Modern pastry chefs and cake designers use various ingredients and tools to create a cake that usually reflects the personalities of the couple. Today, many flavors and configurations are available in addition to the traditional all-white tiered cake. Cutting the cake is an important part of the reception.
