The KIT KAT® Bar got its start across the pond in 1935. Originally known by Londoners as “Rowntree's Chocolate Crisp,” the candy was renamed in 1937 to “Kit Kat® Chocolate Crisp.” While KIT KAT® Bars are a global confection, The Hershey Company has produced the candy in the U.S. since 1970. Today, KIT KAT® Bars come in a variety of new and seasonal flavors to keep candy fans on their toes.
