Preheat oven to 350 degrees F. In a covered large saucepan, cook potatoes in enough boiling water to cover for 15 to 20 minutes or until tender. Drain. Mash with a potato masher or beat with an electric mixer on low speed. Season with the salt and 1/8 teaspoon pepper. If necessary, add a small amount of milk for desired consistency.

Grease four 10- to 12-ounce individual casseroles or custard cups or a 1- to 1-1/2-quart casserole. Spoon potato mixture into prepared casserole(s). In a chilled medium bowl, beat whipping cream with chilled beaters of an electric mixer on medium speed until soft peaks form (tips curl over); fold in cheese. Spoon cheese mixture over potatoes. Place casserole(s) on a baking sheet. Bake, uncovered, about 20 minutes or until lightly browned and heated through. If desired, sprinkle with additional black pepper. Makes 4 servings.
