Boil the potatoes in enough water to cover until fork tender. Drain. Place the potatoes back into the pot on medium, and mash best you can with a potato masher to release the steam. Pour in the heavy cream, & finish mashing the potatoes. Stir the mixture to combine. Stir in the Parmesan cheese, garlic, & fresh chopped parsley. Drizzle in the olive oil, a little at a time - stirring after each drizzle, until all the olive oil is combined. Season with salt & pepper to taste.

Scoop into your serving vessel; drizzle with olive oil & sprinkle on chopped parsley to garnish if desired.
