01 - Cook macaroni in a pot of salted boiling water until al dente. Drain thoroughly and set aside.
02 - In a large skillet or saucepan over medium heat, combine buffalo sauce, cream cheese, and milk. Stir continuously until the mixture is smooth and starts to bubble. Add mozzarella cheese and mix until fully melted and incorporated.
03 - Add shredded chicken to the sauce and stir to combine. Fold in the drained macaroni, ensuring each piece is evenly coated.
04 - Transfer mixture to a lightly greased baking dish. Bake in a preheated oven at 375°F for 10 to 15 minutes, or until the surface is bubbly and lightly golden.
05 - Drizzle with ranch dressing just before serving. Garnish with chopped green onions or parsley as desired.
