The weekly top baker on 'The Great British Bake Off' is called the Star Baker.
Judges award the title to the contestant whose overall performance is considered strongest across that episode's challenges. The decision can reflect a combination of the Signature, Technical, and Showstopper bakes rather than a single winning dish.
The Star Baker title is separate from the series championship. A contestant may receive it more than once, while the eventual winner is decided in the final episode. The judges also name the contestant leaving the competition each week.
The program began on BBC Two in 2010 before moving to Channel 4 in 2017. Its terminology is part of the show's recognizable format, alongside the tent, the technical challenge, and the Showstopper. The answer is therefore a title, not the name of a person or a particular recipe.
