Mashed Potatoes al a Rhonda

We have a tradition at Thanksgiving. I make the turkey and stuffing, and my sister-in-law makes the mashed potatoes, corn casserole and green beans. My stuffing is out of this world (or so I've been told) and her mashed potatoes are just divine.
2 1/2 lbs red potatoes, washed (peel if you wish but not necessary)
1/4 lb (1 stick) butter
1 8oz pkg cream cheese
1/4 cup heavy cream
salt and pepper to taste

Cut the potatoes into quarters and place in large stock pot. Add enough cold water to cover.

Boil for about 15-20 minutes or until soft. (test with fork, if the potato falls off the fork easily the potatoes are done)

Drain and place the potatoes back in the same pot. (the heat from the pot will help dry the potatoes)

Mash the cooked potatoes with potato masher, and while hot add the butter, cream cheese, cream and salt and pepper to taste.
