Double Decker is a brand of chocolate bar manufactured by British company Cadbury, first introduced in 1976.[1] Its name derives from the well-known double-decker bus, with the buses themselves sometimes appearing in advertisements for the product. It is a mixture of milk chocolate, nougat with a hint of coffee,[2] and crisp, crunchy cereal. This has proved to be a very popular recipe, being used in cakes and other confections.[3] The Double Decker is manufactured in Poland[4] since 2011.[5]
