Preheat the smoker. Set your smoker to 275 degrees F using a mild, sweet wood like apple or cherry.
Assemble the s’more bottoms. Arrange the graham crackers in a cast iron skillet, then top each with a chunk of chocolate. Finally, add the marshmallows.
Smoke the marshmallows. Place the skillet on the grates of your smoker, close the lid, and smoke for 10 to 15 minutes.
Melt and finish. This step is optional but amazing. Place the skillet on the top rack of your oven and broil them for 1 to 2 minutes. You can also do this with a torch if you have one handy.
Serve and enjoy! Top your warm, smoked s’mores with the other half of the grahams, serve immediately, and enjoy!
