Slow Cooker Mac and Cheese

One of the gals I work with brought this to a pot luck recently (from frugalginger).  It was a big hit.  I've actually tried a lot of mac and cheese recipes, and this goes towards the top!  Technically, I didn't use macaroni noodles because I was using up some noodles in the pantry, but the results were the same.
Ingredients:  cooking spray, 20 oz of macaroni (cooked), 12 oz of evaporated milk, 1 1/2 c. whole milk, 1/4 c. melted butter, 1 t. salt, 2 eggs (beaten), dash of pepper, 20 oz of sharp cheddar cheese (grated), Paprika (to taste)
Instructions:  
1.  Spray the slow cooker with cooking spray.
2.  Mix the cooled macaroni, milks, butter, salt, pepper, 1/2 cup of the cheese, and eggs.
3.  Pour into slow cooker and top with the rest of the cheese and sprinkle with Paprika.
4.  Cook for 3 hours on low.
