The Great British Bake Off

The contest begins with Cake Week, beginning with a signature challenge to produce a classic Battenberg. For the technical round, Paul sets the contestants the task of making a fruit sponge, and the final Showstopper Challenge gives the bakers a chance to express their creativity.

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.

Noel Fielding and Matt Lucas present Bread Week, which kicks off with a sweet and savoury signature round. For the technical challenge, the bakers are asked to create a tribute to the NHS, while the Showstopper is an ambitiously artistic challenge featuring decorative designs in bread. Judges Prue Leith and Paul Hollywood sample their efforts, and choose this week's Star Baker - and this week's departing contestant.

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?

Matt Lucas and Noel Fielding present the halfway point of the culinary contest, with pastry week. The bakers must put their own stamp on a Cornish classic and are set a retro technical challenge. For the showstopper round, they must concoct a classic tart in a pastry cage, before judges Prue Leith and Paul Hollywood decide who will be this week's star baker and who will be going 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.

Matt Lucas and Noel Fielding host a 1980s-themed episode of the contest. The signature challenge features a classic quiche, while the technical round requires the bakers to master a popular retro sweet treat. For their final showstopper task, the contestants must keep their cool while preparing an ice cream cake before judges Prue Leith and Paul Hollywood pick this week's star baker and decide who will be leaving the tent.

Noel Fielding and Matt Lucas present dessert week of the culinary competition. The signature round features a miniature cheesecake, while the technical challenge features a dish that dates back to the 17th century. Finally, for their showstoppers, the bakers must concoct a jelly art dessert cake constructed of delicate sponge. Judges Paul Hollywood and Prue Leith are on hand to sample the results and decide who will be Star Baker and who will be leaving the tent.

Matt Lucas and Noel Fielding present this year's semi-final, the last four bakers facing three patisserie challenges to decide who will be going through to next week's final. The signature round features plenty of alcohol, while the technical challenge sets the bakers the task of making pastry horns. Finally, for the Showstopper, they must use all the precision they can muster to construct a cake made entirely from smaller cakes.

Noel Fielding and Matt Lucas host the grand final of this year's contest. The last three bakers face three tests of a range of baking skills - a deceptively simple Signature round combining set custard and puff pastry, a Technical celebrating the classic combination of chocolate and nuts, and a magnificent dessert tower for their final Showstopper, before judges Prue Leith and Paul Hollywood select this year's winner.
