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.

The second round of The Great British Bake Off, hosted by Mel Giedroyc and Sue Perkins, continues in the search for Britain's best amateur baker. Eleven bakers remain and this time their pastry skills are scrutinised as the bakers tackle tarts. Over two days the bakers will face three increasingly complicated challenges whilst trying to avoid a soggy bottom.

The contestants start this week with the signature bake, a free-form flavoured loaf that produces a variety of interesting results, including a combination of chocolate and onion. Next is the technical challenge - focaccia - that really separates the wheat from the chaff. Finally, a mammoth six-hour hour challenge requires the bakers to create a display bread basket that is filled with 24 bread rolls.
