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.
