In large mixing bowl add mashed potatoes. Whip until all strings are gone. For best results boil potatoes instead of baking. Add remaining ingredients, mixing until very fluffy and creamy. Place finished potatoes in deep baking dish. Set aside.
Mix all above ingredients together until flour doesn't look white. Crumble over top of potato mixture and bake until golden brown. Heat oven to 325F.
