Choco pie

A choco pie is a snack cake consisting of two small round layers of cake with marshmallow filling and a chocolate covering. The term originated in the United States but is now also used widely in South Korea, Japan, and countries to which it exports, and many other countries as either a brand name or a generic term. Names for similar confections in other places include chocolate marshmallow pie, Wagon Wheels, angel pie (in Japan), and moon pie.
