Preheat the oven to 425°F and have ready a rimmed sheet pan lined with aluminum foil.
Place the sweet potatoes on the pan, drizzle with olive oil and rub into skins.
Bake for 40 minutes or until fork tender. Set aside and allow to cool for 10 minutes or until cool enough to handle.
Cut a line down the center of the potatoes and turn over into a medium-sized mixing bowl. The flesh of the potatoes should easily fall right into the bowl.
Add the Mascarpone, salt, and pepper. Mix together with a potato masher or an electric mixer at medium speed. Serve right away and enjoy.
