In a medium size bowl, beat together cream cheese, ricotta cheese, vanilla and powdered sugar. Mix for about two minutes or until smooth.

Refrigerate mixture until ready to stuff strawberries.

Remove stems from strawberries and slice across so that strawberries will lay flat on a plate. Hollow out the top of a strawberry or make a cross in the top so there is room for filling.

Pipe some filling into each strawberry. Sprinkle with chocolate chips and graham cracker crumbs before serving.
