About

A Delicious Fusion of Chocolate, Caramel and Nougat

Old fashioned Mars logo

We still make MARS bars at the same factory where they were originally produced in 1932. Almost 90 years later, in Slough, England, we can make nearly three million bars a day filled with caramel and nougat, covered in rich milk chocolate - remaining loved and enjoyed by many across the UK.

Despite sweets rationing and a gold ink shortage during World War II, MARS bars were successfully distributed to troops in the UK and prisoners of war in Germany from 1939 to 1945.
