Reese's Peanut Butter Cups were created by former employee of the Hershey Chocolate Company, Harry Burnett Reese in 1928. Reese's Peanut Butter Cups begin with roasting fresh peanuts for Reese's one-of-a-kind peanut butter. The peanut butter and milk chocolate are then dropped and pressed into a mold that gives Reese's Cups their iconic shape.
