Themed kids parties is one of my favorite occasions to make a cake for. This Sonic cake is definitely a favorite of mine because of all the little details that went into it. But I need to let you in on a little secret, only the top tier is actually cake! This particular client wanted a very extravagant cake but didn’t want to have a bunch of it leftover after the party. I frequently suggest to have a “dummy” tier or tiers (a layer that is styrofoam) so that you never have to sacrifice on design but only order the amount of cake you actually need.
