Stacey Dooley, Jade Thirlwall, Katherine Ryan, KSI

Matt Lucas hosts as TV presenter Stacey Dooley, Little Mix's Jade Thirlwall, comedian Katherine Ryan and internet influencer KSI show off their baking skills. They serve up cocktail-flavoured fondant fancies, have their knowledge of pastry tested in the technical and in the showstopper are asked to create a scene showing something they cannot live without - all from biscuit and meringue. Paul Hollywood and Prue Leith judge their efforts.
