Spray 9 x 13 baking dish with cooking spray and set aside.
Using a paper towel blot the potatoes and remove any excess water.
In a large mixing bowl, combine cream cheese, butter, chicken soup, and ranch dressing. Mix until combined.
Add hash browns, shredded chicken, bacon, and 1 ½ cups of shredded cheese to the soup mixture. Stir until combined.
Pour the chicken mixture into the prepared baking dish. Sprinkle with the remaining shredded cheese and then top with corn flakes. Cover the dish with aluminum foil.
Bake 20 – 25 minutes, remove the foil, and bake for an additional 10 minutes. The mixture should be bubbly and the corn flake topping lightly browned.
