Prepare the smoker by adding pellets to the hopper.Preheat the smoker to 300°F. Slice the jalapenos in half lengthwise. Scoop out the seeds and membranes using a spoon.
To a small bowl, add softened cream cheese, shredded cheese, garlic powder, paprika, and pepper. Mix until completely combined.Fill each jalapeno with the cream cheese mixture. Wrap each jalapeno with a half slice of bacon. Use a toothpick to secure the bacon if needed.
Transfer to the preheated smoker, line the smoker with foil, and smoke for 45-60 minutes (depending on size). Smoke until the jalapenos are tender and the bacon is crispy.You can stick them in the oven on broil for a couple of minutes to crisp up the bacon if needed. Remove from the smoker, cool slightly, and serve. Store leftovers in an airtight container in the refrigerator for up to 4 days.
