Mac and cheese- mom's way

This is my mom's recipe and it is comfort food at its finest. Yum!! I can never just have one helping.

Ingredients:
Box of elbow macaroni
1 8 oz block of sharp cheddar cheese
1 stick butter or margarine
2 cups milk
1 tsp salt
2 tbsp flour
Bread crumbs

Directions:
Boil water and cook macaroni according to directions. Drain water and set aside
In a skillet melt butter. Then add salt, flour and milk.
Once it starts to bubble stir in cheese and mix well. (I usually turn the stove down to low when I put the cheese in.)
In a 9x13 baking dish pour macaroni in and then dump cheese mixture over and mix together. I almost always add some Parmesan cheese or whatever I have laying around to make it extra cheesy. Top with breadcrumbs and cook for 30 mins at 350. Enjoy!!!!
