It's the final showdown in the illustrious Great Hall, and hosts James and Oliver Phelps challenge the teams to create a showpiece that reaches at least 6 feet tall and commemorates at least one event that takes place in the Great Hall. The bakers must also include two enchanting culinary effects and incorporate at least two tasting elements. Surprises unfold throughout the finale, including the return of guest judges Warwick Davis, Evanna Lynch and Bonnie Wright, who join judges Carla Hall and Jozef Youssef to crown the first-ever Wizards of Baking champions among a crowd of ecstatic Harry Potter fans.
