The Great British Bake Off

James Blunt, Alison Hammond, Alex Jones and Joe Sugg take part in the charity culinary challenge, under the watchful eye of presenters Sandi Toksvig and Noel Fielding, and judges Paul Hollywood and Prue Leith. For the signature round, they must prepare a batch of decorated traybakes, while the technical challenge involves a classic British staple. Finally, for the Showstopper, they must create a scene out of biscuits depicting what they wanted to be when they grew up.
