Ingredients for Mississippi Mud Cake Recipe

Why is it called Mississippi Mud Cake

According to the Mississippi Encyclopedia, this homemade chocolate cake gets it’s name because it resembles crusted and cracked clay that comes from the banks of the Mississippi River. It’s a variation of Mississippi “mud pies”, which combine sugar, melted butter, chocolate, and eggs in a pie shell.
