The once simple wedding cake has evolved into what today is a multi-tiered extravaganza. The multi-tiered wedding cake was originally reserved for English royalty. Even for the nobility, the first multi-tiered cakes were real in appearance only. Their upper layers were mockups made of spun sugar. Once the problem of preventing the upper layers from collapsing into the lower layers was solved, a real multi-tiered wedding cake could be created. Pillars as decoration existed long before multi-tiered cakes appeared, so it was a natural progression for cake bakers to try using pillars as a way to support the upper tiers. To prevent the pillars from sinking into the bottom tier, icing was hardened to provided the necessary support. .
There is hardly a bride today who can't resist saving the top layer of her multi-tiered cake. Most couples freeze the cake with the intention of sharing it on their first wedding anniversary. The tradition has its roots in the late 19th century when grand cakes were baked for christenings. It was assumed that the christening would occur soon after the wedding ceremony, so the two ceremonies were often linked, as were the cakes. With wedding cakes becoming more and more fancy and elaborate, the christening cake quickly took a back seat to the wedding cake. When three-tiered cakes became popular, the top tier was often left over. A subsequent christening provided a perfect opportunity to finish the cake. Couples could then logically rationalize the need for three tiers --- the bottom tier for the reception, the middle tier for distributing and the top for the christening. As the time between the weddings and the christenings widened, the two events became disassociated, and the reason for saving the top tier changed. Regardless of the underlying reason, when the couple finally does eat the top tier, it serves as a very pleasant reminder of what was their very special day.
