Three more teams compete. In the Miniatures Challenge, the teams must produce 36 St Marc slices, 36 sfogliatelle and 36 small domed cakes invented specially by the teams.

This week, sticky toffee pudding gets the five-star treatment. The teams' extraordinary designs include a model of the Lake District and a brandy snap tower which glows in the dark. Ambitious and risky, but will the judges be impressed? And who will be back to bake again in the semi-finals?

Celebrated chef Tom Kerridge hosts the search for Britain's best team of pastry chefs. In the final heat, three more teams hope to secure their place in the semi-finals. In the Miniatures Challenge, the teams have just three hours to produce 36 dacquoise slices, 36 fruit tartlets and 36 petits gateaux in the shape of a cube. They need to make every batch identical in size and shape and avoid Cherish getting out her ruler. But will they impress Benoit and Claire with their innovative flavour profiles? In the Showpiece Challenge, the team are asked to reinvent a classic homemade dessert as a fine-dining experience. For this heat, chocolate cheesecake is transformed into three stunning showpiece displays. One team takes its inspiration from the ancient Aztecs while another travels back to ancient Greece. The third team opts to avoid a theme altogether, instead focusing on making the best possible cheesecake. Which tactic will pay off when the final scores are revealed?

As the competition reaches the semi-final stage, Tom Kerridge welcomes back Liam's team from the armed forces, the supermarket inventors led by James and Sajeela's Park Lane boys. In the Miniatures Challenge, the teams must once again up their game as the judges set one of the sternest tests of a pastry chef's skill, breakfast pastries. With only three hours to make 144 perfect pastries, there is no margin for error. Then, for the Showpiece Challenge, the teams must construct large and elaborate chocolate containers filled with three different types of confectionery: dipped chocolates, nougat and pÔte de fruits. The teams' designs take inspiration from the world of showbusiness, the far east and a family love story, but which will find favour with the formidable judging panel?

In the second semi-final, three teams must build large and decorative chocolate structures to display different types of sweets.

The final three teams must present a fine-dining dessert banquet with enough desserts to feed 100 guests. Who will triumph?
