Four remaining teams composed of a master cake artist, sugar sculptor and food carver return to battle, and first, they must imagine Santa's disguise when he goes undercover. Then, in the second round, they are challenged to create a delicious world where the animals of the forest celebrate Christmas. At the end of this battle, one more team will be eliminated in the quest for the $50,000 grand prize with help from guest judge Yolanda Gampp, cake artist and host of the online series "How to Cake It."
