A moon pie or MoonPie is a popular confection in the United States which consists of two round graham cracker cookies with marshmallow filling in the center dipped in a flavored coating. The traditional pie is approximately four inches (100 mm) in diameter. A smaller version exists (mini MoonPie) that is approximately half the size and a Double-Decker MoonPie of the traditional diameter features a third cookie and attendant layer of marshmallow.
