Biscuit Week

It's crunch time for the bakers as biscuit week arrives and they are asked to produce their take on filled brandy snaps, followed by a jammy childhood favourite in the technical challenge. In the showstopper, they have to come up with an interactive toy made entirely from biscuit. Noel Fielding and Matt Lucas find out who will be top cookie and who will crumble under the pressure, while Paul Hollywood and Prue Leith judge their efforts.
