Preheat oven to 350 degrees F (175 degrees C).Advertisement
Bring a large pot of lightly salted water to a boil. Add macaroni and cook for 10 to 13 minutes or until al dente; drain.
In a bowl mix together the eggs, milk, and pepper. In a casserole dish, place about a third of the cooked macaroni in one layer, sprinkle with 1/2 of the cheese, then layer the rest of the macaroni and cover with the remaining cheese. Coat evenly with the egg-milk mixture. Lastly, cut slices of butter and place them on top of the cheese.
Bake in a preheated oven for 30 minutes or until the cheese is completely melted.
