Mel Giedroyc, Sue Perkins and the contestants have reached the grand final. After seven gruelling weeks the three finalists face their biggest challenge yet - baking for The Great British Bake Off's street party.

Inside the Bake Off tent new levels of stress are reached and the pressure hits boiling point as they must bake not only for judges Mary Berry and Paul Hollywood, but also friends, family and former Bake Off contestants. None of them have baked on this scale before.

In order to be crowned the victor, they need to bring together their skills, making a selection of petits fours and - for the first time ever in the Bake Off - puff pastry.

Among their offerings are mille-feuille, mini Victoria sponges, strawberry and cream meringue nests and miniature strawberry and rhubarb cheesecakes.

Only one can be crowned Britain's Best Amateur Baker and take home the Bake Off trophy. Show less
