A Kentucky coal miner asked for a tasty treat as big as the moon for his lunch pail, and our bakery in Tennessee has been satisfying big, hungry appetites ever since.Delicious - Each Double Decker MoonPie is made with 2 large marshmallows sandwiched between big crisp graham crackers. We don't stop there, our graham cracker and marshmallow sandwich is then layered with a delicious coating of Banana, to create the ultimate marshmallow pie.
