Mel Giedroyc and Sue Perkins take the eight passionate home bakers who made it through the first round to Scone Palace near Perth to make biscuits and teatime treats. Judging their efforts are renowned baking writer Mary Berry and master baker Paul Hollywood. Over two days the home bakers are set three increasingly difficult challenges as they bake their signature biscuits, attempt many a baker's nemesis – scones – and finally a tower of petit fours with meringues, choux pastry and macaroons. As the bakers battle it out, Mel and Sue find out how the digestive became Britain's favourite biscuit; ask what's so Scottish about shortbread and discover why Sir Ranulph Fiennes has the world's most expensive biscuit. Which of the eight bakers will wow the judges with their originality and skill? And which two bakers will fail to make it through to the next round?
