Boil the elbow macaroni following the directions on the box. Whisk the egg and milk together in a bowl.
Spray a 9x13 smoker safe dish with cooking spray. Pour the pasta into the pan. Top with the butter, cubes of Velveeta, shredded cheese, seasonings, and the egg/milk mixture.
Stir everything together. Smoke on the smoker at 300 degrees for about 1 hour or until all the cheese is melted. It helps to stir a few times while it is cooking.
Bake at 350 degrees for about 30 minutes stirring at least once time half way through. Enjoy!
