It's the quarter-final and the teams make Black Forest gateaux and mini roulades, before going back to the 70s as they create disco-inspired sugar chocolate showpiece desserts.

Liam Charles and Tom Allen present the grand final, which sees the remaining three teams pour all of their patisserie passion, prowess and precision into their last two challenges. For the first, they must produce hats made entirely of chocolate, and modelled by the teams themselves. But that's not all. Alongside the headwear, they have to make 24 filled chocolates and 24 confections - all in just four hours. The final seven-hour challenge sees them create a banquet to feed 60 people. Who will walk away with this year's title?
