Whip the cream cheese, vanilla and sugar until fluffy. Spoon the mixture into a ziptop bag, and seal. Cut a small corner off the bag to create a piping bag.

Wash the strawberries and cut off the leafy tops.

Cut an X into the narrow end of the strawberry, making sure not to cut all the way through.

Pipe a bit of the filling into each strawberry.

Top with chocolate chips, if desired. Serve immediately or refrigerate until ready to serve.
