Place the peeled and chopped potatoes into a large pan filled with enough salted cold water to just cover the potatoes. Boil until tender.

When the potatoes are done boiling, drain them and transfer to a mixer.

Add the butter and cream, and whip the potatoes until they are smooth and creamy.

Stir in the grated black truffle cheese until melted and smooth.

Salt & pepper to taste.

Enjoy!
