Crock-Pot Macaroni and Cheese

8 ounces elbow macaroni, cooked (I don't cook mine, just throw it in with everything else)
1 12 ounce can evaporated milk
1 1/2 cups whole milk (I use skim cause the whole seems too much)
2 large eggs, beaten
1/4 cup (1/2 stick) butter, melted
1 teaspoon salt
dash of pepper
2 10 ounce bricks sharp cheddar cheese, grated (about 5 cups)
dash of paprika

In a large 4-quart crockpot sprayed with cooking spray, mix the macaroni, milks, eggs, butter, salt, pepper, and all but 1/2 cup of the grated cheese.

Sprinkle the reserved cheese over the top of the mixture and then sprinkle with paprika. Cook on low heat for 3 hours and 15 minutes.
