The Great British Bake Off ™ (often abbreviated to Bake Off or GBBO and referred to in the United States as The Great British Baking Show ™) is a streamed British baking competition, in which a group of amateur bakers compete against each other in a series of rounds, hoping to impress the judges with their baking skills. One contestant in The Great British Baking Show ™ is eliminated in each round, and the winner is selected from the three contestants who reach the final.

The Great British Baking Show ™ operates on a weekly elimination process to find the best all-around baker from the contestants, who are all amateurs. In each episode, the bakers are given three challenges based on that week's theme: a signature bake, a technical challenge, and a show-stopper. The bakes are assessed by the judges who then choose a "Star Baker" for the week, and a contestant is also eliminated. In the final round, three bakers are left and a winner is chosen from the three.
