Begin by preheating your oven to 350°F (175°C). Lightly spray a 10-12 inch casserole dish (either oval or rectangular) with non-stick spray, then set it aside.
In a large mixing bowl, combine the dry corn muffin mix, sour cream, the drained whole kernel corn, the creamed corn, and the melted butter. Use a rubber scraper to mix all the ingredients together thoroughly until well incorporated.
Pour the prepared casserole mixture evenly into your greased baking dish, spreading it smoothly to the sides.
Place the dish in the preheated oven and bake for 40 minutes.
After the initial 40 minutes, carefully remove the casserole from the oven. Sprinkle the shredded cheddar cheese evenly over the top.
Return the casserole to the oven for another 10 minutes to allow the cheese to melt and achieve a slight golden brown color.
Once baked, remove the casserole from the oven and let it cool for approximately 10 minutes before serving.
