Preheat your smoker to 275°F.
Slice the pork belly into 1 1/2 inch cubes.
Combine the brown sugar, paprika, salt, chili powder, garlic powder, onion powder, and black pepper, mixing to break up any lumps.
Generously spread the mixture over the pork belly cubes, rotating the cubes to ensure that all sides are equally seasoned.
Place the pork belly cubes in your smoker. Close the lid and cook for 3-4 hours or until they reach an internal temperature of 165°F.
During this cooking process, combine the ingredients for our BBQ Hero Sweet & Sticky BBQ Sauce in a small saucepan and bring it to a simmer for 10 minutes.
Once the smoked pork belly has reached an internal temperature of 165°F, transfer the cubes to a large aluminum pan.
Pour your homemade BBQ Sauce over the pork belly cubes and add 4 tbsp of cubed butter and cover with aluminum foil.
Place the pan into your smoker for another 1-2 hours, or until they reach an internal temperature of 205°F
Remove the pan from your smoker and let rest at room temperature for 20 minutes before serving.
