The pièce montée was the pièce de resistance for the 2014 season of the Great British Bake Off. I dubbed mine The Magic of Halloween. It features a dark chocolate cake with cherry filling topped with a pumpkin cake, which in turn is topped with a croquembouche. The profiteroles in the croquembouche are filled with orange pastry cream, drizzled with dark chocolate and spiraled with spun sugar. Spiced macarons and gingerbread black cats round out this tower of treats.
