Another very special occasion for a cake - a baptism or christening. The terms are sometimes used interchangeably, but they do have different meanings for different faiths.
Here is a 2-tier cake that I made for a Christening. There is a small 3rd tier that the client requested so they can save the topper.
A 2-tier baptism cake. Vanilla Butter Cake on the top tier and Chocolate Velvet cake on the bottom tier.
