As the latest series of The Great Celebrity Bake Off comes to a close this Sunday, four more contestants will be hoping to impress judges Paul Hollywood and Prue Leith to win themselves the coveted title of Star Baker. While the show follows the same format as the usual series, as it includes a baking challenge, a technical challenge and finally a showstopper challenge, the Celebrity edition has the added bonus of also helping to raise money for the Stand Up To Cancer appeal.
