Daisy Ridley, Rob Beckett, Alexandra Burke, and Tom Allen make millionaire shortbread, a fruity tart and their pet hates in cake form.
James McAvoy, Anne-Marie, David Baddiel, and Dame Kelly Holmes make decorative tarts and a savoury technical, and render their spirit animals in cake.
Dizzee Rascal, Nick Grimshaw, Philippa Perry, and Reece Shearsmith tackle vegetable slices, a royal technical and a selfie made entirely from biscuit.
Stacey Dooley, Jade Thirlwall, KSI, and Katherine Ryan make cocktail-flavoured fondant fancies before creating a show-stopping biscuit and meringue scene.
Anneka Rice, John Bishop, Nadine Coyle, and Ade Adepitan tackle choux buns before making a cake that represents something from their bucket list.
Emma Willis, Clara Amfo, Blake Harrison and Alex Horne take on three challenges, as they make decorated biscuits in the Signature, madeleines in the Technical, and a choux sculpture which embodies their secret talent in an ambitious Showstopper.
