Chocolate marshmallow pies differ from regular chocolate-coated marshmallow treats in that there is a cake- or cookie-like layer above as well as below the marshmallow filling – that is, the marshmallow filling is sandwiched between two layers of cake or cookie, the entirety then being enrobed in chocolate.
Some local names for chocolate marshmallow pies are:
"Chocolate marshmallow pie" (a generic term) in the United States (e.g., Little Debbie Chocolate Flavored Marshmallow Pies).

"Moon Pie" (a brand name of Chattanooga Bakery) in the United States, particularly the Southern United States.

"Scooter Pie" (a brand name of Burry's) in the United States, particularly in the Northeastern United States.

"Choco pie" (originally a brand name, now a common noun as a generic trademark), originally in South Korea but now also in Russia and other parts of East Asia, South Asia and Southeast Asia.

"Angel pie" (a brand name of Morinaga) in Japan.

"Wagon Wheels" (a brand name used by both Burton's Biscuit and Dare Foods) in the United Kingdom, Canada, Australia and certain other countries.
