The Great British Bake Off (series 2)

For their first challenge, the bakers were asked to bake 24 cupcakes in two hours. They were allowed to make two different types of cupcakes. For the technical challenge, the bakers were asked to bake a Coffee and Walnut Battenburg cake using Mary Berry's recipe in two hours. The cake needed to have the perfect sponge which held its form (perfect symmetry), distinguish flavours, and a smooth exterior. For the showstopper, the bakers were asked to bake a chocolate tiered celebration cake with elaborate, multi-layer design in five hours.

For the signature bake, the bakers were asked to bake a savoury quiche in 2 hours. For the technical challenge, the bakers were asked to bake a Tarte au Citron using Mary Berry's recipe in 1+1⁄2 hours. For the showstopper, the bakers were asked to bake 24 mini sweet tartlets, in two different flavour combinations.

For their signature bake, the bakers were asked to bake a free form flavored loaf (not using a tin) in 3+1⁄4 hours. The technical challenge gave the bakers 3+1⁄2 hours to bake a Focaccia, using Paul Hollywood's recipe. The showstopper required the bakers to produce a 2 part display: a basket made of bread, then filled with 12 sweet and 12 savory rolls, in the space of 5 hours.

In this episode, two bakers were eliminated rather than one baker.

For the signature bake, the bakers were give 1+1⁄2 hours to make 12 biscuits of their choice; the biscuits should not be too soft, too hard or too crumbly. The technical challenge gave the bakers 1+1⁄2 hours to bake 24 brandy snaps. For the showstopper, the bakers were asked to produce a macaron display, consisting of 120 macarons in 3 different flavors; they had 5 hours to complete it.

The signature challenge asked the bakers to produce a hearty family pie using either a rough puff or flaky pastry, in 2+1⁄2 hours. For the technical challenge, the bakers were asked to bake a batch of 6 miniature pork pies (using a hot water crust pastry) in 2+1⁄2 hours, using Paul Hollywood's recipe. It was a 2-day bake challenge — to give the filling time to set overnight the pies were judged the next day. For the showstopper, the bakers were asked to bake a meringue pie — a fruit and/or custard pie topped with meringue — in 3+1⁄2 hours.

Once again, in this episode, two bakers were eliminated instead of one baker.

For their signature bake, the quarterfinalists were tasked to produce a cheesecake in 2¹⁄₂ hours. For the technical challenge, the bakers were asked to bake a chocolate roulade in 1+3⁄4 hours using Mary Berry's recipe. For the showstopper, the bakers were asked to create a Croquembouche-inspired bake in 5 hours.

For the signature bake, the semi-finalists were given 2 hours to bake a layered mousse cake, with the judges seeking a light sponge and a rich mousse. In the technical challenge, the bakers were asked to bake 12 identical Iced Fingers to be filled with cream and jam, using Paul Hollywood's recipe. For the showstopper, the bakers were asked to produce a selection of three different pastries using the same laminated pastry dough — which must be crisp on the outside and soft on the inside — for all three.

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.

Both episodes nine and ten were masterclasses by Paul and Mary, where they demonstrated how to make the Technical Challenges that they had set throughout the series. Episode nine showed the first four of the series; Coffee and walnut Battenberg, Tarte au Citron, Focaccia and Brandy Snaps. Episode ten showed the last four of the series; Pork pies, Chocolate roulade, Iced fingers and Sachertorte. Episode eleven went back and revisited the bakers from series one to catch up with the contestants.
