This is the BEST corn casserole you have ever had! It is rich, creamy, cheesy and super delicious. The secret is the Jiffy corn muffin mix and the sour cream swirl at the end!
Preheat the oven to 350˚F.
In a large casserole dish, add the melted butter, Jiffy mix, corn, creamed corn, egg, and half of the cheddar cheese (about 1 cup.) Mix until everything is combined.
Dollop the sour cream evenly over the top, then use a knife to gently swirl it into the casserole. Sprinkle the remaining cheese over the top.
Bake on the middle rack in the oven for 40-45 minutes or until the middle is set (cooked through.) Remove from the oven and serve warm. Enjoy!
