Follow these simple steps to whip up your own Creamy Mac and Cheese:

1. Boil the Pasta: In a large pot, bring salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente. Drain and set aside.

2. Make the Roux: In the same pot, melt the butter over medium heat. Once melted, stir in the flour and cook for about 2 minutes, constantly stirring to avoid browning.

3. Add the Milk: Gradually whisk in the whole milk until smooth. Continue stirring until the mixture thickens, about 5-7 minutes.

4. Incorporate Cheese: Remove the pot from heat. Stir in the shredded sharp cheddar and mozzarella cheese until fully melted and smooth.

5. Season the Sauce: Mix in garlic powder, onion powder, mustard powder, and season with salt and pepper to taste.

6. Combine with Pasta: Fold the cooked macaroni into the cheese sauce until evenly coated.

7. Optional Baking Step: If you prefer a crispy top, preheat your oven to 350°F (175°C). Pour the macaroni and cheese into a greased baking dish.

8. Add Breadcrumbs: Sprinkle breadcrumbs over the top of the macaroni and cheese for added texture and crunch.

9. Bake: Place in the oven and bake for 5-10 minutes or until the top is golden brown and crispy.

10. Let it Cool: Once baked, allow it to cool for a few minutes before serving to let the sauce set slightly.
