According to the local weekly:
“The Moon Pie was created in 1917 when Earl Mitchell Sr, a bakery salesman, visited a bakery that catered to coalminers. When asked what they were interested in, the coal miners told him something filling and easy to eat as they often didn’t get a break for lunch. When asked how big the baked goods needed to be , one coal miner held up his hands to frame the boom–“about this big,” he said. Thus, a legendary Southern treat was created. moon pies now range in flavors from banana to the ever-popular, but elusive peanut butter.”
In 1972 officials of the Mobile, Al Mardi Gras banned cracker jack boxes because they were too dangerous. Moon pies became the official Mardi Gras treat in 1974. What does that mean? People hurl them at you from parade floats.
