The Great British Bake Off

Challenges include a retro classic technical and a showstopper birthday cake.

Noel Fielding and Sandi Toksvig host the second round of the culinary competition, which this time focuses on biscuits. For the signature round, the contestants must concoct a luxurious chocolate-coated bake.

The bakers tackle a signature bake designed to be shared.

It is Dairy Week and Prue and Paul have set some tricky challenges including a technical one that dates back to Henry VIII and a showstopper usually found at Indian weddings.

The judges set challenges inspired by the Roaring Twenties, including a slapstick signature bake and a tiered showstopper featuring a twist on their favorite tipple.

The cake layers stack up in an elegant and challenging bake for dessert week; a spherical celebration cake.
