Reese's Peanut Butter Cups are the No. 1 selling candy brand in the United States[3] and consist of a milk, white, or dark chocolate cup filled with peanut butter, marketed by The Hershey Company. They were created by H. B. Reese, a former dairy farmer and shipping foreman for Milton S. Hershey. Reese left his job as a shipping foreman for The Hershey Company to start his own candy business.[4]
