Peel and cube the potatoes.

Place potatoes into a large cooking pot and cover with water. Bring to a boil and then boil until fork-tender, about 20 minutes. (Or pressure cook on high for 10 minutes).

Drain the potatoes. Stir in softened butter, heavy cream, salt, and pepper.

Mash with a potato masher or fork until no lumps remain.

Serve warm.
