It's week two, and the sandwich biscuit signature challenge sees bakers trying to blend biscuit and filling. There's a technical task set by Paul Hollywood that no one has tried before. And a final showstopper challenge that takes the biscuit and is literally game changing. Paul and Prue Leith cast a critical eye over the contestants' efforts, while new hosts Sandi Toksvig and Noel Fielding settle into their roles. As ever, it remains to be seen which of the unlucky bakers will be shown the door.
