Overview: The three finalists face two days of baking challenges before one of them is crowned Junior Bake Off Champion 2016. Today, for their first ever signature challenge they must produce two different canapes made with rough puff pastry, and whilst the bakes themselves aren't a surprise, the guests they are making them for are. Sam and Mark welcome vloggers Marcus Butler and Oli White to the tent to assist the judges in tasting the bakes, much to the delight of the finalists, who are massive Marcus and Oli fans. After all that excitement, the judges really step up the pressure by giving the bakers their final and toughest technical challenge yet - a surprise recipe for chocolate passion fruit meringue pies.
