Baked Macaroni and Cheese

1 Box of any style noodles ( I like the cork screw)
2-3 cups of shredded chedder cheese (I like a mix of mild and sharp)

Cook noodles according to package. In a saucepan add 4 cups of milk and a stick of butter. Warm until the butter is melted. Thicken the mixture by mixing a little bit of cornstarch with water. (2-3 tbsp. of corn starch with a small amount of water just enough to disolve the cornstarch.) Add the cornstarch to the milk and stir until sauce thickens. Put the noodles in a 9x13 pan add cheese and pour milk over.
Bake 350 for about 35 min.

**My mom would usually add leftover cut up ham in with the mixture
