In a medium mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.
Add the granulated sugar and vanilla extract to the cream cheese, and continue to mix until well combined.
Gently fold in the whipped topping until the mixture is smooth and fluffy.
Stir in the mini chocolate chips, reserving a few for garnish if desired.
Pour the cream cheese mixture into the graham cracker crust, spreading it evenly.
Refrigerate for at least 2 hours to allow the dessert to set properly.
Before serving, drizzle chocolate syrup over the top and sprinkle with reserved chocolate chips.
