Family Favorite Hot Fudge Cake

Why I Love This Recipe
This dessert started with my mother who used to make it for us. I continued it with my kids and now my grandkids. This gets made just about any time we are together.
It originated as an 8X8 pan size so the ingredients reflect our best efforts to make it work for a 9X13.
