Which company made the world’s largest chocolate bar in 2011?

Thorntons made the world’s largest chocolate bar in 2011.

The British confectionery company created the record-breaking bar in the United Kingdom to mark its centenary. It weighed about 5,792.5 kilograms, making it vastly larger than a normal retail chocolate bar and requiring substantial quantities of chocolate and other ingredients.

The bar was produced as a publicity and charity event rather than as an ordinary commercial product. After the record attempt, it was broken into smaller pieces and distributed for charitable purposes.

Records involving oversized food can change when a later achievement is officially verified, so “world’s largest” should be understood in the context of the Guinness World Records title and its date. The 2011 Thorntons bar remains a frequently cited chocolate-bar record.
