Momo's Corn Casserole

We love this recipe!  It's perfect as a dish to pass, and leftovers reheat well.  It came from my daughter Momo, but if someone knows an original source for this, please let me know so that I can include the information here. 

In a 2 quart casserole dish, mix together:
1 can corn, drained
1 can creamed corn
1/2 cup milk
1 cup sour cream
1 stick butter, melted
3/4 cup shredded cheddar cheese (optional)
1 box Jiffy corn bread mix
1 teaspoon salt
1/2 teaspoon black pepper

Bake uncovered at 375 for 30-35 min, or until center is set; top with another 3/4 c shredded cheddar cheese, return to oven till cheese is melted, about 5 minutes.
