I make something similar that I've always heard called cornbread casserole.

Mix up your cornbread batter, add blackeyed peas and chopped ham or bacon . Place in a greased dutch oven and bake. Dad would put sausage and cheese in his cornbread on occasion. My dad was from Arkansas and my mom from Ohio. Mom loved dad dearly and tried to make home cooking for him on occasion, which meant blackeye cornbread and ham. However she always cooked the cornbread in a muffin pan and dad always used a baking pan. I took after dad I guess because I make mine in a cast iron frying pan.
