Wedding Cake Tip #1 Do Your Homework Look at tons of wedding cake photos so you know your options. If you have a custom style in mind, cut out pictures, snip fabric swatches, and pull from other resources. Before you start sketching out cake plans, learn about a few basic terms, such as fondant and buttercream. (Fondant makes for a very neat, put-together design but doesn't taste amazing; buttercream tastes great but can't be molded or colored like fondant.) Hint: While fondant is normally draped over a cake that's been frosted with buttercream, a high-end baker can roll out the fondant in a thin layer. That way, the fondant looks superb while buttercream dominates your taste buds.
