Preheat the oven to 350°F. Place the potatoes in a baking dish and bake in the preheated oven for 50 minutes. Remove from the oven and use a spoon to scoop the meat of the potatoes from the skins. Use a whisk or a ricer to mash the potatoes into a smooth consistency. Add butter and hot cream and continue to mix. Season with salt and pepper as needed.
