I'm looking for a sweet potato cake recipe from the South Mississippi area. Some of its ingredients are...

mashed, hot sweet potatoes
buttermilk
cocoa
walnuts
raisins
flour
sugar
cinnamon?

Sorry, I can't remember the rest, but it was baked in a bundt cake pan. I'd love to get a copy of this cake recipe.
