For 12 Serving(s)
In a large bowl, mix together soup, sour cream, butter, onion and cheese. Set aside.
Place potatoes in a shallow, lightly greased 3-litre/3-quart baking dish. Fold the soup mixture into the potatoes, and spread the mixture evenly in the dish. Season with pepper, and then sprinkle the corn flakes evenly on top.
Bake at 350°F for 45 minutes or until the mixture is hot and bubbling.
