Bake the potatoes. Preheat oven to 400°F (200°C). Pierce the potatoes with a fork, place them on a baking sheet, and bake them for 1 hour. Remove from the oven and let them cool to the touch.
Scoop out potatoes. Cut each potato in half lengthwise. Use a spoon to scoop out some of the potato flesh, leaving about ¼-inch thickness around the skin.
Season the potatoes. Turn the oven to broil and place the rack about 6 inches below the broiler. Brush the potatoes with butter both on the outside and inside. Place them on a baking sheet and season with a sprinkle of salt, pepper and garlic powder. Broil for 6 to 8 minutes, until slightly golden and crispy.
Add filling. Remove the sheet pan from the oven and add a sprinkle of cheese and bacon to each potato.
Broil again. Place the potatoes back in the oven, and broil for another 3 to 4 minutes, until the cheese is melted.
Add garnishes and serve. Before serving, dollop with sour cream and garnish with sliced green onion.
