Put sliced hot dogs into an aluminum pan. Use mustard as a binder.
Mustard
Apply rub liberally to mustard covered hot dogs.
3 tbsp Your favorite BBQ Rub
Smoke the Hot Dog Burnt Ends
Set your smoker to 225F. We used post oak but use whatever hardwood you prefer.
Place hot dog burnt ends on the grill so that they aren't touching.
Smoke for 1 hour.
Glaze Hot Dog Burnt Ends
After 1 hour, put the smoked hot dogs into an aluminum pan.
Add your favorite barbecue sauce and 2 tablespoons of unsalted butter.
2/3 Cup Your Favorite BBQ Sauce, 2 tbsp Unsalted Butter
Either increase your smokers temperature to 375F or bring inside to your oven.
Place into your oven and stir every 10 minutes or so just so the melted butter is incorporated into the sauce. You also want all surfaces of the hot dogs covered in sauce.
After some time the glaze will start to caramelize. This process took us around 30 minutes. However, be sure to keep an eye on them as it depends on how much sauce you add.
Once the glaze is set and the sugars have caramelized, bring outside and serve with toothpicks to eat and enjoy!
Notes
Don't fret if some of the casings crack, it's more or less bound to happen, especially in an oven.If you don't have my rub, any sugar-based barbecue rub will suffice here.
