In a pot, cover the potatoes with cold water and season the water with salt.
Bring to a boil, then simmer until potatoes are fork tender.
In a separate sauce pan, gently melt the butter and then add the cream.
Add to the potatoes and incorporate using a hand blender.
For extra added fluffiness, finish in a drink blender with an additional tablespoon each cream and butter.
Season with salt and black pepper.
