Spray Crock-Pot with non-stick cooking spray. Boil the macaroni in water for six minutes and drain. Mix butter and cheese over medium-high heat in a saucepan. Stir until the mixture melts. In your Crock-Pot, combine the cheese mixture, sour cream, soup, salt, milk, mustard, and pepper. Add the drained macaroni and stir. Cook in the Crock-Pot for 2 to 2 ½ hours on low heat, stirring every half hour. Cook just until it’s hot. Don’t overcook or your macaroni will turn to mush!
