Preheat the oven to 400°. Scrub the potatoes and poke them with a fork.
Rub with olive oil and sprinkle coarse salt over the potato skins. Place the potatoes directly on the rack in the oven and bake for 50-60 minutes or until the potatoes are soft.
Meanwhile, cook the bacon, so it is crispy. Remove the bacon and place it on a plate lined with paper towels. Set aside.
Remove potatoes and allow them to cool completely. Then, cut them in half lengthwise. Then scoop out the baked potato filling leaving a thin layer in the skin.
Add potatoes, sour cream, pepper, garlic powder, butter, and milk in a large bowl. Mix with an electric hand mixer or potato masher until creamy and smooth.
Add green onions, ½ the bacon, and ¾ cup of cheese to the potato filling. Fold them in until well combined.
Spoon the filling into the potato skins. Then, top with remaining cheese and bacon.
Bake for 15-20 or until the cheese has completely melted.
