Lay out 2 long pieces of heavy duty aluminum foil or NON-WAXED pink butchers paper on top of each other on the counter, long enough to double wrap the rack of ribs front and back with the two pieces. Repeat with the other half rack if you cut the rack into two pieces.
Place 3 pieces of butter on each set of aluminum foil, then drizzle with the BBQ sauce.
Place the baby back ribs face down into each pile of aluminum foil and ingredients.
If you would rather not use the wrapping ingredients listed above, place the ribs in the foil face up and add a small amount of apple juice, soda, or beer to the aluminum foil to add some moisture.
Wrap the ribs tightly in the double layer of aluminum foil or butchers paper and place back in the electric smoker.
You can turn the smoker up to 275°F at this step to ensure proper breakdown of fat and collagen.
Cook until the ribs reach an internal temperature of 195-200°F for competition style ribs, 200-210°F for pull off the bone ribs, and 210-215°F for fall off the bone ribs. This may only take 1 to 1.5 hours rather than 2.
Remove the ribs from the electric smoker using tongs or heat resistant gloves.
