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.

Reproducing the surroundings of the English village fête, which originally inspired the show, the series is filmed in a huge tent in scenic gardens.

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.
