For their final signature bake, the finalists were asked to bake 12 mille-feuille in 2+1⁄2 hours. For the technical challenge, the bakers were asked to bake a sachertorte in 2 hours and 40 minutes. For their final showstopper, the bakers were asked to bake 3 different types of petits fours: meringue, sweet pastry, and sponge-based, on the theme of British Summertime, within 4 hours.
