Mississippi Mud Cake

This was my Mom's recipe.  It was passed to her from someone at church I think.  I fixed it and it was a real crowd pleaser.  I copied exactly as I had copied from hers.  It's sortof listed in step by step format as far as ingredients so be sure to read throughout as not all of the ingredients are listed at the top.
