The Great British Bake Off returns with five special Stand Up To Cancer episodes. In each episode Sandi Toksvig and Noel Fielding are joined by four different celebrities aiming to impress judges Paul Hollywood and Prue Leith with their baking skills. Over five episodes, Paul and Prue set 15 exciting new baking challenges, pushing the celebrities to their baking limits. But only one celebrity per episode will be awarded the coveted star baker apron. On your marks, get set, bake for Stand Up To Cancer! In the first episode, the four brave celebrities ushered into the Bake Off tent are comedian Harry Hill, Spandau Ballet's Martin Kemp, actor and writer Roisin Conaty, and veteran broadcaster Bill Turnbull. The first challenge is a bake sale classic - cupcakes. The technical challenge is fiery. And there's a demanding showstopper challenge - a 3D biscuit scene recreating the best day of their life. So who will fall flat and who will rise to the occasion to be crowned star baker? (thetvdb.com)
