Creating Buffalo Chicken & Mac and Cheese is simple if you follow these steps:

1. Cook the Pasta: In a large pot of salted boiling water, cook the elbow macaroni according to package instructions until al dente. Drain and set aside.

2. Prepare the Sauce: In a large saucepan, melt the butter over medium heat. Once melted, add the cream cheese and stir until smooth.

3. Add Milk: Gradually pour in the milk, stirring constantly until the mixture is well combined and creamy.

4. Incorporate Cheese: Slowly add the shredded cheddar cheese, stirring until completely melted and smooth.

5. Mix in Spices: Add garlic powder, onion powder, salt, and black pepper to the cheese sauce. Stir to combine.

6. Combine Chicken and Sauce: In a large bowl, mix the shredded chicken with buffalo sauce. Then, pour the cheesy sauce over the chicken and mix until well combined.

7. Combine with Pasta: Add the cooked macaroni to the chicken and cheese mixture. Stir until the pasta is fully coated in the creamy sauce.

8. Prepare for Baking: Preheat the oven to 350°F (175°C). Transfer the mac and cheese mixture to a greased baking dish.

9. Add Breadcrumbs: Sprinkle breadcrumbs evenly over the top of the mac and cheese mixture for a crunchy topping.

10. Bake: Place in the preheated oven and bake for 20-25 minutes, or until the top is golden and bubbly.
