Step 1

Preheat the oven to 350ºF. Prepare a 8"x12" baking by greasing it with oil or melted butter.

Step 2

In a large mixing bowl, combine the cream-style corn, whole-kernel corn, Jiffy corn muffin mix, diced onion, diced jalapeno peppers, egg, and shredded cheese. Mix just until combined.

Step 3

Pour the casserole mixture into the baking dish.

Step 4

Cube the butter into small pieces and layer them on top of the casserole mixture.

Step 5

Sprinkle some extra cheese on top of the butter.

Step 6

Cover the dish with aluminum foil and bake for the first 40 minutes. Uncover and bake for another 5-10 minutes or until the cheese on top is melted and slightly golden.

Step 7

Serve and enjoy warm!
