Bake potatoes. Cut baked in half lengthwise; scoop pulp into a bowl and set shells aside.
Combine potato pulp with butter; beat until smooth.
Spoon potato mixture into the potato shells, mounding slightly. Place on baking sheet. Top with crumbled bacon and cheese. Bake at 375° for 15 minutes, or until cheese is melted. Cut in halves or quarters to serve as an appetizer.
