Place potatoes on a pan then place in oven preheated at 400 degrees then bake for about 1 hour or until soft to touch.
Remove potatoes and allow to cool slightly the slice in half lengthwise. Scoop out the inside but leaving a thin shell. Place the scooped potato into a bowl with sour cream, heavy cream, cheddar cheese and garlic powder and mash using a fork.
Add chopped scallion, bacon bits, salt and pepper and mix to combine.
Place potato back into the hollowed skins, equally dividing the mix between the 8 shells.
Top with additional shredded cheese then place in oven that heated to 375 degrees and bake for 15 minutes until the cheese is melted.
Remove from oven and top with additional bacon bit and scallion. Serve warm.
