Preheat oven to 400 degrees F.

Using a sharp knife, make crosswise cuts in each potato, about 1/8-inch apart, stopping about 1/4 inch from the bottom. Add butter slices to between the cuts; season with salt and pepper, to taste.

Transfer potatoes to a baking sheet. Place into oven and bake until the outsides are browned and crisp, about 1 hour. Top with cheese and bake until melted, an additional 5 minutes.

Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Transfer to a paper towel-lined plate.

Serve potatoes immediately, topped with sour cream, bacon and chives.
