Macaroni and Cheese

8 ounces elbow macaroni, cooked and drained
4 cups (16 ounces) shredded sharp Cheddar cheese, divided
1 (12 ounce) can evaporated milk
1 1/2 cups milk
2 eggs
1 teaspoon salt
1/2 teaspoon black pepper

Place the cooked macaroni in a 3-1/2 quart or larger crockpot that has been coated with nonstick cooking spray. Add the remaining ingredients except 1 cup of the cheese; mix well. Sprinkle with the remaining 1 cup cheese, then cover and cook on LOW for 5 to 6 hours, or until the mixture is firm and golden around the edges. Do not remove the cover or stir until the mixture has finished cooking.
