Mississippi mud pie is a chocolate-based dessert pie that is likely to have originated in the U.S. state of Mississippi. The treat contains a gooey chocolate sauce on top of a crumbly chocolate crust. The pie is usually served with ice cream. The name "Mississippi mud pie" comes from the dense cake which resembles the banks of the Mississippi River. It is believed that this dish was created by home cooks after World War II because it was made of simple ingredients that could be found at any supermarket and did not require any special cooking tools. Its earliest known reference in print is 1975.
