Victoria Wood, Alexa Chung, Chris Moyles and Kayvan Novak are the four celebrities doing battle in the tent on The Great Comic Relief Bake Off this week.
Ed Byrne takes the reigns keeping an eye on the celebrities as they get started on the first challenge, the signature bake. The celebs are asked to serve up some unique twists on a tray bake.
Their challenging tray bake recipes must hit the right spot if they are to impress judges Paul Hollywood and Mary Berry.
They are allowed to bake anything they like as long as it is in a tray. It could be anything from brownies to a flap jack.
