The toughest Bake Off on TV returns, inviting teams from top hotels and restaurants to do battle. This time, six teams tackle Linzer tortes, Bakewell tarts, and a red velvet cake.

The five teams of pro pastry chefs make layered fruit cake slices, lemon-shaped desserts and an éclair tower. But one team's patisserie journey is about to come to an end...

Things are getting tougher for the teams with an unseen secret recipe challenge and a magnificent showpiece featuring moving parts

The remaining teams bake two dozen gateaux Basques and tartes Tatin before reinventing teatime classic the Battenberg Cak, where only the extraordinary will do.

The remaining teams feel the heat rising as they must produce pristine, perfect cheesecake slices, pear-shaped desserts, and a themed pièce montée with two different flavours of choux buns.

Chocolate Week features a secret recipe challenge, and a Showpiece in which the teams have five hours to produce a magnificent sun, sea and sky-themed extravaganza with three types of chocolates. Their creations must demonstrate a mastery of chocolate, consummate technical ability, artistic flair - and a moving part.

The best six teams from both sets of heats are combined as they battle it out for a place in the quarter-final. For Holiday Week, the teams must create brioches polonaises, savoury Danish pastries and a jaw-dropping sugar Showpiece with fruit pastilles, fudge, and marshmallows.

In the quarter-final of the competition, the teams are challenged to prepare 24 ice-creams and 24 doughnuts in just four hours, before creating a spectacular Showpiece incorporating confectionery, sugar work and chocolate. The lowest-ranking team must leave the competition, whilst the remaining four secure their place in the semi-final.

Just four teams remain for the semi-finals, with challenges including the creation of an impressive tower of tarts and a spectacular piece of gourmet theatre known as live plating. At the end of the challenge, the teams are given three minutes to transform their table - and their cake - into a gastronomic work of art, with three of them securing their places in the grand final.

Three teams fight to be crowned the winners of 2019 as they create a stunning afternoon tea and mind-blowing wedding feast.
