Pour heavy whipping cream into the bowl of a stand mixer or a large mixing bowl. Pour in sugar. Use a hand mixer, or the whisk attachment on a stand mixer, to whip cream until stiff peaks form. Scoop the nutella into the bowl. Fold it together using a rubber spatula until all of the whipped cream is brown and loses its streaks. Scoop into serving dishes, or use a piping bag if you are being fancy. Serve immediately or refrigerate until ready to serve.
