My mom's twice baked potatoes

1. Preheat the oven to 400°F. Place the washed potatoes on a baking sheet and bake for 1 hour. After baking, lower the oven heat to 350°F.
2. Once potatoes are baked, carefully cut off the top of each potato (save them). Scoop out the insides with a spoon and place in a bowl.
3. Add the sour cream, chives, sharp cheddar, milk, salt, and pepper to the scooped-out potato mixture. Mix thoroughly until combined.
4. Stuff the potato mixture back into the potato skins, mounding it generously. Sprinkle some more cheddar cheese on top of the stuffed potatoes. Place the saved potato tops (also sprinkled with cheese) on the baking sheet alongside the stuffed potatoes.
5. Place the potatoes back into the preheated 350°F oven and cook for an additional 15 to 20 minutes, or until the potatoes are warmed through and the cheese is melted and bubbly. Enjoy!
