Place the potatoes directly on the center rack in the oven and cook until a fork passes easily through the center, about 45-60 minutes depending on the size.
While the potatoes are cooking in a skillet over medium high heat cook the bacon until nice and crispy. Remove from the drippings and set aside. Retain some of the drippings for the potatoes later if desired.
Once the potatoes are done remove from the oven but keep it on. Allow the potatoes to cool for about 10 minutes before slicing in half.
Scoop out the inside of the potato leaving about ⅛ of an inch left around the outside to refill.
Using a masher or potato ricer mash the potato and then add the butter, sour cream, chives, cheese and bacon. Add some of the bacon drippings at this point if desired. Fold to mix everything evenly.
Spoon or pipe back into the carved-out potatoes. Place on the lined sheet pan and bake for another 15 minutes.
