Reese's Peanut Butter Cups were created by Harry Burnett Reese a former dairy farmer who worked at the Hershey chocolate factory. He began making his own candy in the basement of his home in 1923 and sold peanut butter cups to Hershey in 1963 after his death — his company was purchased for $23.5 million. Today Reese's is one of the best-selling candy brands in the US.
