The Great British Bake Off

The series gets underway with cake week - during which two of the bakers will be sent home. The first stage of the challenge features a fruit cake, while the technical is a retro classic that requires intricate decoration. Finally, for the showstopper, the contestants must create the birthday cake they wish they had received as a child.
