In a large bowl or mixer, cream together cream cheese, sugar and vanilla extract until smooth, then mix in raspberries until broken down and incorporated, yet still a little chunky.
Fold in cool whip with a rubber spatula until just combined, then freeze for 1 1/2-2 hours, or until firm.
Using a small ice cream scoop or tablespoon, scoop 1-2-inch balls of cheesecake mixture and roll into a circle. Then, roll cheesecake balls in crushed graham cracker crumbs until completely coated.
Transfer to a parchment lined baking sheet and continue with remaining cheesecake balls.
Place cheesecake balls in freezer until ready to eat, then let sit at room temperature before serving.
