Creating the Ultimate Creamy Baked Mac and Cheese is a breeze with these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Pasta: In a large pot, boil salted water and cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
3. Make Cheese Sauce: In a medium saucepan, melt the butter over medium heat. Add the milk and bring to a simmer.
4. Add Cheese: Gradually whisk in the shredded cheddar and mozzarella cheese until fully melted and smooth. Season with salt and pepper to taste.
5. Combine Pasta and Sauce: Add the cooked macaroni to the cheese sauce and stir until well combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish. If desired, sprinkle breadcrumbs on top for extra crunch.
7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until bubbly and golden on top.
8. Cool and Serve: Allow it to cool for a few minutes before serving to let the cheese set slightly.

These straightforward steps ensure that you achieve that creamy, cheesy perfection everyone loves!
