The remaining teams enter the breathtaking world of Gringotts Wizarding Bank to face off in three head-to-head battles. Hosts James and Oliver Phelps ask the bakers to create 3-foot showpieces inspired by the resplendent main hall, the network of tunnels and carts, and the underground vaults. The creations must also include at least one enchanting effect and two tasting elements, plus a surprise hidden treasure! Judges Carla Hall and Jozef Youssef are joined by Harry Potter alumnus Warwick Davis to decide the winner, and one team will be sent home.
