At Merci Beaucoup Cakes, it's Marc's moment to shine as he creates a buttercream groom's cake that is a combination of the groom's favorite cigars and his surprise trip to Australia. Marc affectionately calls this the Cigar-roo cake. Cake Alchemy is overjoyed when they are presented with a beehive design for an engagement cake. Lauri wants to test Stephanie and Melanie's abilities by creating a beehive suspended from a branch. Will their tree structure hold the twenty-pound beehive? Will it survive the delivery? The team at Christopher Garren's Cakes is about to usher in the art deco period, building a cake that features a sculpted dancing couple, a five-foot tall skyscraper and more piano keys than one can count.
