In the bowl of a mixer, combine the cream cheese, 2 or 3 tablespoons powdered sugar or Splenda, and 1 teaspoon pure vanilla extract.
Spoon the cream cheese mixture into a piping bag.
Fill the holes in the tops of the strawberries using the piping bag full of cream cheese mixture. Be sure to cover the entire top of the berry (where the leaves once were).
Dip the cream cheese filled end of the strawberry into the graham cracker crumbs.
