Mississippi mud pies may have begun in the 1970s as a variation on mud cake, a dessert which was popular in the American South during World War II.[4][5][10][11]
Another story says that Mississippi mud pie may also have originated from the Vicksburg-Natchez area near Jackson, Mississippi[4] in the 1920s.[8][11] In this version, a woman named Jenny Meyer worked as a waitress in the Vicksburg area after having lost her home when the Mississippi River flooded. During one of her shifts, the waitress noted that a melting chocolate pie resembled the Mississippi River's muddy banks, which is how the dessert gained its name.[5][8][10]
