Twix is a chocolate bar made by Mars, Inc., consisting of biscuit applied with other confectionery toppings and coatings (most frequently caramel and milk chocolate). Twix bars are packaged in pairs, although smaller single bars are available.
The product was first produced in the United Kingdom in 1967, and introduced in the United States in 1979. Twix was called Raider in mainland Europe for many years before its name was changed in 1991 (2000 in Denmark, Finland, Norway, Sweden and Turkey) to match the international brand name. The name Twix is a portmanteau of twin biscuits, or 'twin bix'.
