An Extra Slice of... Chocolate Tarte

Jo Brand is joined by three celebrity Bake Off fans to dissect the penultimate week in the tent, when the bakers tackled chocolate. As well as unseen footage from the BBC One show, Jo and the panel will taste bakes brought in by the studio audience and look at photos of bakes from viewers at home - the stonkers and the stinkers. Jo will interview the last baker to leave before the final. What will the panel think of the bakers' signature chocolate tarts? Who rose to the chocolate souffle technical? Whose show-stopping 3D chocolate centrepiece was the centre of attention? And which baker will the panel tip to be crowned the Great British Bake Off Champion 2015?
