The Great British Bake Off: An Extra Slice, sometimes shortened to An Extra Slice is a British television show made by the BBC and filmed at The London Studios as a spin-off from the reality TV hit series The Great British Bake Off which airs on BBC One. Each week, host Jo Brand is joined by three different celebrity Bake Off fans. Jo shines a spotlight on the good, the bad and the soggy bottomed from the week’s episode with chat, unseen footage from the BBC One show and an interview with the week’s eliminated baker. The studio audience are challenged to bring a bake in from home from the week’s baking theme, be that bread, pastry, or cakes, and viewers are invited to share photos of their efforts too.
