1Heat 1 inch water (salted if desired) to boiling in Dutch oven. Add potatoes. Cover and heat to boiling; reduce heat. Cook 20 to 25 minutes or until tender; drain. Shake pan with potatoes over low heat to dry.
2Mash potatoes in large bowl until no lumps remain. Beat in milk in small amounts, beating after each addition (amount of milk needed to make potatoes smooth and fluffy depends on kind of potatoes used). Add cream cheese, butter, salt and pepper. Beat vigorously until potatoes are light and fluffy.
