The competition starts to heat up during Chocolate Week, as Prue Leith and Paul Hollywood set three tricky challenges to test the remaining bakers. There's a deceptively simple traybake in the Signature, a Technical packed full of chocolate and nuts, and a celebration Showstopper that pushes the bakers' skills with white chocolate to the limit. Who will impress Prue and Paul enough to keep their place in the tent, and who will be heading home?

Noel Fielding and Matt Lucas host the show's first ever Japanese week. For the signature challenge the bakers tackle a Japanese version of the Asian staple, steamed buns, while the technical round involves a tricky recipe involving multiple layers. The showstopper round is themed around kawaii - the Japanese love of all things cute.
