Set your Bradley smoker to 250 (use sage or sweet wood)
Using the butter coat the bottom of the cast iron skillet and add the block of Velveeta cheese.
Set a timer for 60 minutes and stir (the cheese should be mostly melted by this time)
Set another timer for 30 minutes, now add the 2 cans of rotel ,milk and optional ingredients. Stir and place back into the smoker for 30 minutes.
