Crispy Crunch is a hard chocolate bar with a crispy peanut butter flake inside that is made by Cadbury in Canada. Harold Oswin, an employee of William Neilson, developed "Crispy Crunch" in 1930.[1]
History
Harold Oswin was a candy roller in Neilson's hard candy room and joined the company when he was fourteen years old.[2] He was promoted to candy maker in the late 1920s. When a chocolate bar contest was announced, he submitted his concept; peanut butter coated in a mixture of sugar, molasses and vanilla, dipped in chocolate.[2][3] Harold won the contest and received a $5.00 prize. The original recipe called for a log-shaped bar. Williams Neilson management made the decision to flatten the bar to the shape that it is today. Oswin died in the mid-1990s.
