Preheat oven to 400F.
Wash potatoes. Place them on a baking sheet and poke each potato several times with a knife so they can let out steam while cooking.
Bake potatoes at 400F for one hour or until fork tender. Remove from oven and allow to cool off for a few minutes before handling.
Cook strips of bacon in a pan until crispy and cooked through. Let bacon cool on a plate lined with a paper towel. Once the bacon has cooled completely, break or slice bacon strips into crumbles.
Once the potatoes are cool enough to handle, cut off the top portion, about the top quarter, and scoop the potato into a large mixing bowl. Keeping the potato peel in tact, leave a small border of potato inside the peel so it holds its shape. Discard the peel from the top quarter. Set aside the potato shells to stuff later.
After all the potatoes have been have been scooped out, add salt, pepper, onion powder, and butter to the mixing bowl. Use a potato masher to mash all of the potato and butter together.
Add in the sour cream, ½ of the shredded cheese, bacon crumbles, and chives. Fold in to combine.
Fill each potato shell with the filling and pile it high.
Top each potato with the remaining cheese.
Return to the oven and bake for 15-20 minutes until the cheese on top has melted completely and slightly browned.
