Step #1 Cook macaroni on the stove top per package directions.
Step #2 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).
Step #3 Combine the milk mixture with the cheese soup & grated cheese in the crock pot.
Step #4 When the macaroni is done, drain & add it to the crock pot.
Step #5 Stir to mix.
Step #6 Cook on low setting for 2 1/2 hrs.
