Peel and rinse off the potatoes. Thinly slice potatoes, about 1/4".
Place in a saucepan and cover with cold water at least 1- 2" above the potatoes.
Bring to a boil and reduce heat to medium. Place a wooden spoon over the top and cook until potatoes can be flaked apart with a fork, about 15 minutes.
Drain and place in a large mixing bowl.
Place the butter and cream into a large microwavable cup along with the salt and pepper. Heat until butter is melted. Watch carefully so it doesn't accidently spill over.
Add some of the cream/butter mixture gradually into potatoes while mixing on a low speed. Begin to add a little more as you increase to medium speed. Increase the speed to high and only add the amount of cream/butter as needed to acquire your desired mashed potato consistency. Adjust seasoning, including adding more butter, if needed.
