Truly, Madly, Orangey
Light sponge, dark crackly chocolate and the smashing zingy orangey bit - and 1g of fat per cake. So tangily delicious, it's hard to keep your hands off them.
Seriously - have you ever seen a McVitie's Jaffa Cake and tried not to eat it?
Go on, try - see if you can keep your hands off it. We dare you. We double dare you.
