Double Decker is a British brand of chocolate bar currently manufactured by Cadbury. First introduced in the UK in 1976, 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,[1] and crisp, crunchy cereal.
This has proved to be a very popular recipe, being used in cakes and other confections.[2]
