The ingredients and density of the cake also influence how many people it can serve. For example, cakes made out of dense fruit will serve more people than a standard flour cake of the same size. When selecting a cake size, it is also important to allow for a few extra servings. Some people may not be satisfied with the traditional size of a cake slice, and others may decide to attend at the last minute.
