9 potatoes, peeled and cubed

    6 ounces cream cheese

    1 cup sour cream

    2 teaspoons onion powder

    1 teaspoon salt

    1/4 teaspoon ground black pepper

    2 tablespoons butter

 

  Bring a large pot of salted water to a boil. Drop in potatoes, and

 cook until tender but still firm, about 15 minutes.

 

  Transfer potatoes to a large bowl, and mash until smooth. Mix in the

 cream cheese, sour cream, onion powder, salt, pepper and butter. Cover,

 and refrigerate 8 hours, or overnight.

 

   Preheat oven to 350F. Lightly grease a medium baking dish. Spread

 potato mixture into the prepared baking dish, and bake in the preheated

 oven about 30 minutes.
