This is a delicious, easy, homemade mac & cheese recipe. I originally found it on a freezer-cooking website. But I could never freeze any of it - it gets eaten too fast! It's great for potlucks; kids and adults all love it.
Cook macaroni on the stove top per package directions.
Meanwhile, dissolve the powdered milk in the fluid milk (this will be easier if the milk is warm - but it's not necessary - it's OK if a small amount of powdered milk is not completely dissolved).
Combine the milk mixture with the cheese soup and grated cheese in the crock pot. When the macaroni is done, drain and add it to the crock pot. Stir to combine.
