Christopher Garren's Cakes is delighted with an order for a wedding cake that incorporates futuristic architectural design elements. Of course, Christopher just can't help himself and ends up taking his vision way over the top. Lindsey, Marjie, Crystal and Hasung help him materialize his plan, which keeps growing and growing...until it reaches six feet! What could go wrong? Merci Beaucoup Cakes receives an order for an outdoors reception. Marc inadvertently makes the bottom layer too big for the refrigerator. Now it's up to Reva to decorate a cake that has to be assembled on site -- a dreaded situation for every cake decorator. The Cake Girls take an order for a wedding cake that is inspired by the bride's favorite fabric design. Brenda wants the bride to get the cake she wants, while Mary wants to follow her own vision. As always, it's a showdown between sisters, with a cake stuck in the crossfire.
