Reese's Peanut Butter Cups are peanut butter-fille chocolates. They were created in 1928 by Harry Burnett Reese, a former dairy farmer and shipping foreman for Milton S. Hershey. The H. B. Reese Candy Co., established in the basement of Reese's house in Hershey, Pennsylvania, merged with the Hershey Company in 1963. Reese started making peanut butter cups around 1928, along with other types of candy.
