Christopher Garren's Cakes receives an order for an anniversary cake, from a couple of return customers who want a variation on their castle wedding cake. Of course, Chris has some ideas about how to make it better the second time around. The CakeGirls are challenged to make a cake, featuring a retro 60s circle pattern, look au currant. Brenda suggests fondant, but Mary disagrees. Mary cooks up a new way to create the mod circle pattern but things don't go smoothly for long. At Cake Alchemy, Lauri is tasked with creating a hexagon-shaped, colorful cake that's covered in a frenzy of flowers.
