Cream Cheese Mashed Potatoes

In a large pot, cover potatoes with water and season with salt. Bring to a boil and cook until totally soft, 16 to 18 minutes. Drain and return to pot. Add cream cheese and use a potato masher to mash potatoes with cream cheese until smooth.  Meanwhile, in a small saucepan over medium heat, melt butter with milk until warm. Pour mixture over potatoes and stir until completely combined and creamy. Season with salt and pepper.
