The semifinals kick off inside the legendary Gringotts Wizarding Bank, where hosts James and Oliver Phelps ask the remaining four baking teams to create showpieces that magically bring an iconic Harry Potter creature to life. The fantastical creations must also include a bold smoky or spicy tasting element inspired by the Hungarian Horntail. Special guest Warwick Davis, who played Professor Flitwick in the Harry Potter films, joins judges Carla Hall and Jozef Youssef to decide which teams move on to the grand finale.
