Cut stems off of the strawberries and place stem-side down on on cutting board. Cut each strawberry lengthwise into quarters, stopping just before knife hits cutting board, so berries stay intact or cut crosswise in thirds. Place on a serving platter.



Place mascarpone cheese, heavy cream, sugar and vanilla in a medium bowl and beat with an electric mixer until cream is thickened and smooth. Place mascarpone mixture in a piping bag with a star tip attached or a plastic bag and cut off one corner of the bag to pipe. Slowly pipe the mascarpone cream into the berries until filled.
