You can test if the potatoes are tender with a fork. Drain the water out of the pot.

  • Cream: Stir together the cream cheese, sour cream, heavy cream, butter, salt, and pepper in a saucepan over medium heat until smooth. Pour the mixture over the mashed potatoes and continue to mash until the cream is worked into the potatoes.
