Preheat oven to 400 ° F and spray a 9x13 baking dish with cooking spray.
In a large bowl, combine the creamed corn, muffin mix, chiles, sour cream, egg, cumin, and ½ cup of the shredded cheese.
Bake for 20-25 minutes or until edges are golden brown and the middle is set.
Use the back of a wooden spoon (or any other utensil) to make dents in the top of the surface.
In a medium bowl, combine the chicken and the enchilada sauce and pour over the top of the baked corn mixture. Sprinkle with remaining 1 ½ cups of the shredded cheese.
Bake for 5-10 minutes or until cheese is melted.
Remove from oven and let cool slightly. Slice into squares and top with sour cream, diced avocado, diced tomatoes, and cilantro if desired.
