Matt Lucas and Noel Fielding present Biscuit Week. The Signature challenge involves a sophisticated combination of fruit, nut and chocolate, and the bakers must then produce two takes on a tropical Technical. For the Showstopper round, they are challenged to create an elaborate table setting made entirely from biscuits, before judges Paul Hollywood and Prue Leith decide who will be crowned Star Baker and who will be leaving the contest this week.
