Slice off a thin slice from the top end of strawberry (where attached to green) so that the strawberry can stand on a flat surface. Then make two deep cuts on tip of strawberry (forming a cross), going 2/3 down the length of the berry. Repeat with all berries.
In a stand mixer, add cream, sugar and Nutella and whip on high speed until peaks form, stiff enough for piping. It won't be as stiff as regular whipped cream because of the Nutella oils, but you should get it solid enough to pipe. Place Nutella whipped cream into piping bag. Open up strawberry tip like flower petals and place piping tip inside berry and fill with Nutella cream. Once strawberries are finished, store them in the fridge until ready to serve.
