Hosts James and Oliver Phelps welcome nine pairs of gifted professional pastry chefs and cake artists to Warner Bros. Leavesden Studios, home to the iconic sets of the Harry Potter films. For their first challenge, the bakers must create an edible showpiece that is at least 2 feet tall, includes at least one magical effect, and tells the story of their shared love of Harry Potter. Plus, each team member must make a tasting element that showcases their individual specialty. Expert culinary judges Carla Hall and Jozef Youssef decide which bakers will earn a ticket to board the Hogwarts Express train to the next challenge!
