Based on the hit UK series, “The Great British Bake Off,” the American version is hosted by Nia Vardalos & husband Ian Gomez, and is judged by Mary Berry & Johnny Iuzzini. The show premiered as “The Great Holiday Baking Show” but changed the name for its second season. It stars some of the nation’s best amateur bakers as they compete in a series of themed challenges and eliminations, all hoping to be crowned Baking Champion.
