Preheat oven to 350 degrees.
Spray 9x13 baking dish with nonstick cooking spray.
Mix uncooked macaroni noodles, shredded chicken and 1/2 of the cheese mixture in a mixing bowl. Spread in casserole dish.
Mix milk, both cans of soup in mixing bowl. Pour soup and milk mixture over the chicken mixture in casserole dish, stir lightly to ensure that all noodles are covered.
Spread the remaining 1/2 of the cheese mixture on top.
Cover with foil (I like to spray the foil with cooking spray first) and bake for 1 hour.
Remove foil and bake an additional 10 minutes.
