When potatoes are cool enough to handle, cut each in half lengthwise. Scoop out inside of each half into medium bowl, leaving thin potato shell on each. Set shells aside. Mash potatoes with potato masher or electric mixer on low speed until no lumps remain. Add cream cheese, butter, 2 tablespoons of the milk, the salt and pepper; stir or beat until smooth and fluffy. If needed, add more milk. Stir in bacon, chopped chile and 1/2 cup of the cheese.
