Preheat your oven to 350.
In a microwave safe bowl, melt the butter fully, and allow to cool to the touch.
Add the eggs and sour cream and whisk to combine.
Stir in the corn kernels, creamed corn, and chipotle peppers and all but ¼ cup of the cheese. Stir to combine.
Add the jiffy mix and stir until just combined. Try not to overmix, as that will cause the casserole to be tougher.
Heavily grease an 8x8 baking dish with butter, and then pour the casserole mixture into the dish. Top with the ¼ cup of cheese you held back earlier, and bake for 35-45 minutes. Casserole should be browned and puffed up slightly. A toothpick inserted in the middle should come out clean.
Cool for 10 minutes before serving.
