It's the last of the Junior Bake Off heats, and just one place remains in the quarter-finals. Judges Graham Hornigold and Allegra McEvedy want the four hopefuls Ben, Grace, Purdey and Tom to produce iced ring doughnuts for their technical challenge. Then, on the hottest day in the tent so far, they are looking for a 3D biscuit construction depicting an iconic landmark in the show-stopper challenge. Hosts Sam and Mark are on hand as the icing thaws, biscuits melt and the bakers race against the clock and the temperature to keep their biscuit creations vertical and to win that coveted last place in the next round of the competition.
