Moon Pies are a popular snack food consisting of two round cookies filled with marshmallow and coated in a layer of chocolate, vanilla, or banana-flavored icing. They were first created in the early 1900s in the southern United States and have since become a beloved treat, especially in the American South. These sweet snacks are often associated with the Mardi Gras celebration, where they are thrown from floats during parades. Moon Pies are available in various sizes, including mini and regular, and are enjoyed by people of all ages for their unique combination of flavors and textures.
