Preheat the oven to 350°F and lightly coat an 8×11 casserole dish with cooking spray.
In a large bowl, combine the cornbread muffin mix, corn, chopped green chiles, cream, eggs, melted butter, sour cream, seasoning and cheese.
Stir until just mixed and no more dry spots remain. Do not over mix.
Pour the batter into the prepared casserole dish.
Bake for 55 minutes, or until the top turns a light golden brown.
Remove and allow to cool for 5 minutes before serving.
