Curly Wurly is a brand of British chocolate bars currently manufactured by Cadbury UK. It has been formerly known as Wig Wag and Marathon Bar. A delicious soft caramel centre wrapped in rich milk chocolate, Curly Wurly is a wonderful chocolate and chewy caramel treat. One of England’s most popular candy bars, wheat-free and gluten-free. This caramel chocolate bar resembles two flattened, intertwined serpentine strings and carries a flavour you won't forget. Cadbury Curly Wurly is great either cold or at room temperature. A cold Curly Wurly Chocolate Bar, fresh from the fridge, can be easily broken into bite-size chunks and shared with friends.
