Baked Macaroni and Cheese

I had a couple people over for dinner and served this as a side. One of the guests brought up how much they disliked boxed mac and cheese, and how it was obvious that this dish was NOT from a box. I just kept my mouth shut. It's super easy with just a few add-ins. My recipe I'm posting is a tiny bit different from the one on the Kraft website. I triple the topping (using 18 crackers instead of 6) and I use black pepper instead of cayenne. Try it and see if you can fool someone. :)
