Four new pastry chefs are taking on Duff Goldman's Dessert Games in Guy Fieri's market. First, the chefs must turn Guy's favorite diner classic into a sweet diner dessert imposter. Next, the chefs must repurpose a premade cake into an impressive dessert. Finally, the two remaining chefs play a game in which cake candles determine the special ingredient and the special event tied to their decadent chocolate dessert. Which dessert chef will win the $10,000 prize?
