Preheat the oven to 350 degrees Fahrenheit and spray a 9X13 baking pan with a non-stick cooking spray.
In a large bowl, stir together the corn, creamed style corn, corn muffin mix, sour cream and melted butter until combined.
Pour the mixture evenly into the 9X13 baking dish.
Bake for 45 minutes.
Top the casserole with the shredded cheddar cheese. Bake for an additional 5-10 minutes until the cheese is melted and the top of the casserole has browned.
Remove from the oven, let the casserole sit for 5 minutes. Then the casserole is ready to serve and enjoy!
