1Cook the elbow macaroni according to the package instructions. Drain and set aside.
In a medium saucepan, melt the butter over medium heat.
Stir in the flour and cook for about 1 minute, until the mixture is bubbly and smooth.
Gradually add the milk, stirring constantly to avoid lumps. Continue to cook and stir until the mixture thickens and starts to bubble.
Add the shredded cheddar cheese, salt, and black pepper. Stir until the cheese is completely melted and the sauce is smooth.
