Rinse dirt off of potatoes, peel, and slice into medium-sized cubes/chunks.
Add potato cubes to a pot and rinse 2x with water, draining in between.
Fill pot of potatoes with fresh water about 2 inches above potato cubes.
Bring pot to a boil over medium-high heat.
After boiling place on the lid, turn temperature down to medium-low, and cook for 15 minutes (fork or spoon will easily slice through potato when fully cooked).
Drain cooked potatoes and pour into a dish or glass bowl
Use a potato masher or electric hand mixer to mash potatoes until desired texture, and sit aside.
Add butter, cream, salt, and pepper to the empty pan just used to cook potatoes and heat over medium on the stovetop for 1-2 minutes. Stir to combine
Pour melted butter mixture into mashed potatoes and stir with a spoon just until combined.
Serve and enjoy!
