Mac & Cheese - My Mom

Pasta:
2cups of dried elbow macaroni
Sauce:
1/4 cup of butter
2 tablespoons all-purpose flour
2 cups of milk
4 ounces (half a package) of cream cheese, softened
2 teaspoons of Dijon mustard
1 package of yellow cheddar cheese; half shredded half cubed
1 package of white cheddar cheese; half shredded half cubed
salt, eyeball it
pepper, eyeball it
Topping:
1 cup of bread crumbs, i use the Italian seasoned
2 tablespoons of butter

Heat the oven to 400*. Cook the macaroni according to its directions.
While that is going on, melt the 1/4 cup of butter in a saucepan until sizzlng, stir in flour. Cook over medium heat, stir until the flour is smooth and bubbly in the butter. Add milk, mustard, salt and pepper. Add cream cheese (i like to cube it to make it easier to melt). When the cream cheese has melted, add the white and yellow shredded cheese. Stir until melted.
Add cheese cubes to the cooked and drained macaroni. Add sauce and stir together. Pour into a baking pan/casserole ungreased.
Add crumb topping (which is stirred in a small bowl). Bake for about 20mins/until golden brown.

Homemade Mac & Cheese is the best. I used to make this all the time for my roommates in college, they used to plan other meal items around this. My mom modified this from another recipe and its definitely hard to stop eating. With it being so cold, it was great to have comfort food :) 
My only suggestion is to not use deli cheese. I use Cabot, deli cheese seems to be really salty and it gives it a weird taste. I always use a little less salt or pepper because someone can always add more.
