Mac and cheese cups are a fun twist on the classic comfort food. Cook macaroni according to package instructions and mix it with a creamy cheese sauce made from cheddar cheese, milk, and butter. Spoon the mac and cheese mixture into greased muffin tins and top with additional cheese. Bake them in the oven until the cheese is melted and bubbly. These individual-sized portions are perfect for little hands and can be served as a main dish or a side.
