The 12 new bakers don their aprons and head for the iconic tent for cake week. Starting with cake week, the bakers' first signature challenge is to make a madeira cake. It's a well-loved cake, but which of our bakers will try to impress by reinven... (more)ting this classic, and who will play safe in a bid to get perfect madeira with its traditional crack? With one challenge out the way, the bakers face their first technical - Mary's frosted walnut cake, a pre-war classic that is as British as they come. Light sponge sandwiched with buttercream and covered with sweet meringue, this technically challenging cake is one of Mary's favourites, and no-one wants to disappoint the queen of baking. Day Two, and the bakers have to go all out to impress with their first show-stopper, the black forest gateau. This retro classic from the 70s has it all - chocolate, cherries and cream. It's ripe for a reinvention, and these 12 bakers are ready and willing. 12 new bakers, 30 new challenges. On your marks, get set... bake!
