Peter's gluten free dark chocolate and orange sponges was wrapped in a polka dot marzipan. 

Peter: "John Whaite (winner of series three of The Great British Baking Show ™) said that his mum taught him to "listen" to it. If it's still wet, then it's going to sound like it's boiling away. But if it's just a nice, moist cake, it's just got a gentle sound to it. So that was a good tip from The Great British Bake Off ™. "

Judging

Prue Leith: "Nice, thin marzipan. The chocolate's got a lovely flavour to it. Decadent. And actually it's the same with the orange. Gluten free flour for sponges, really does work. That's a great battenberg. "

Paul Hollywood: "I love the polka dots, love the texture of the chocolate one. It's both crumbly and moist, which is quite difficult to make happen. "
