Double Decker 1946

First introduced in 1976, its name derives from the double-decker bus.

There also existed a 'Double Decker - Nuts' launched in 2004, which had the advertising slogan "crispy, crunchy, chewy and nutty". This chocolate bar was essentially a Double Decker with nuts contained within the nougat layer; however it has since been discontinued. At the time it was distinctly aimed at males, and featured in Coronation Street credits during 2004.
