Here, Susan at Oh My! Creative started with a plain yellow 2-tiered store bought cake and turned it into a fun cake worthy of a party! Even if you buy the cake, it usually turns out to be less expensive decorating it yourself than ordering a full cake with the custom decor.
This is a great shortcut, or if you have a sudden emergency (i.e. cake falls off the counter-gasp!) this is a great solution.
