Momys Macaroni and Cheese

This is a recipe I adapted from the Momys recipe module. I tweaked it just a bit and my husband said it is the best he has ever had!

1-1/2 cups elbow macaroni
3 Tbsp butter
2 Tbsp all-purpose flour
½ tsp salt
pepper
2 cup milk
1 cup cheddar cheese
1 cup American cheese
Topping:
½ cup bread crumbs
1 Tbsp butter
3/4 tsp garlic salt
Parmesan cheese
Cook elbow macaroni in boiling, salted water until tender; drain. Melt butter; blend in flour, salt and dash of pepper. Add milk; cook and stir until thick and bubbly. Add cheeses; stir until melted. Mix cheese sauce with macaroni. Put in casserole dish. In food processor blend topping ingredients until well blended. Sprinkle on top of casserole. Bake at 350 degrees for 35-40 minutes.
