The Clark Bar is a candy bar consisting of a crispy peanut butter based core enrobed in milk chocolate. It is similar to the Butterfinger and 5th Avenue bars. Introduced in 1917, it has been manufactured by the New England Confectionery Company (Necco) since 1999.


Today, the Clark Bar uses its original formula pioneered by Irish immigrant David L. Clark in Pittsburgh, Pennsylvania in 1917. It was acquired by Beatrice Foods in 1955, then Leaf in 1983. In late 1990, the manufacturer considered consolidating operations in Chicago, but the Pittsburgh area managed to retain the brand with the firm moving all operations from a Chicago's O'Hare suburb to the north side of Pittsburgh in the fall of 1991.[1][2] In 1996 when Hershey acquired Leaf's North American operations, it became independent again with headquarters retained in Pittsburgh. It was bought by NECCO in 1999.[3]
