Bake the potatoes until fork tender. Let cool slightly.
Slice off the tops and carefully scoop the potato into a mixing bowl, leaving a sturdy shell.
Add the butter, milk, sour cream, salt, and pepper. Mash until creamy.
Spoon the mixture back into the potato shells.
Bake at 350°F for 15-20 minutes until heated through.
Kid Chef Tip: Sprinkle shredded cheddar cheese, chopped green onions,chives, bacon bits, or a little ranch seasoning over the potatoes before the final bake for extra flavor.
