Reduce the heat to medium and mix in the creamed corn, cream cheese, 1/2 cup of milk, 2-5 tablespoons of buffalo hot sauce, and the spices. Stir until the cream cheese is fully melted. Next, incorporate the cheddar and mozzarella cheeses, stirring until both cheeses are melted.
Add the cooked chicken, crumbled bacon, and blue cheese (if using) to the mixture. Stir in the pasta until everything is well-coated, adding more milk if necessary to reach your desired consistency. Optionally, garnish with fresh parsley before serving.
