Title: The Great British Bake Off (series 2)
Content:  The second series of The Great British Bake Off started 14 August 2011 with twelve amateur bakers. Unlike series one, the competition was held in a single location – the grounds of Valentines Mansion, a 17th-century mansion house in Redbridge. In addition to their on-screen presenting, Mel Giedroyc and Sue Perkins also took over the narration, which had been done by Stephen Noonan for the previous series. Series two also introduced the "star baker" award for the most impressive performer each week. Three and a half thousand people applied for the competition, and twelve were selected. Each episode was filmed over two fourteen-hour days. The competition was won by Joanne Wheatley.

Content:  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. During the Showstopper round, Rob accidentally dropped his cake.

For the technical challenge, the bakers were asked to bake 12 identical Iced Fingers. Using Paul's recipe, they were to be filled with cream and jam. For the showstopper, the bakers were asked to bake 3 types of pastries. The bakers had to use the same dough — which must be crisp on the outside and soft on the inside — for all three. In this episode, none of the bakers were individually highlighted as Star Baker, as the judges decided all four deserved commendation for reaching the semi-final.
