The Great British Bake Off BBC1, 8pm
New series. Twelve contestants begin the battle to be named Britain’s best amateur baker, facing tasks devised by judges Mary Berry and Paul Hollywood, who have created 30 new challenges to test their baking skills and creativity. Their first signature challenge is to make a Madeira cake, before they attempt to bake a frosted walnut cake in the technical challenge. Day two of the contest sees the contestants going all out to try and impress the judges with their first showstopper.
