Rinse the strawberries under cold water and gently pat them dry with a paper towel. Slice off the tops and carefully hollow out a small portion of the inside using a small spoon or a paring knife, creating space for the filling.
In a mixing bowl, combine the softened cream cheese, powdered sugar, and vanilla extract. Use an electric mixer to beat the mixture until smooth and creamy.
Gently fold in the whipped topping until fully incorporated, creating a light and fluffy cheesecake filling.
Using a piping bag or a small spoon, fill each hollowed strawberry with the cheesecake mixture, generously overfilling them if desired.
Sprinkle the tops of the filled strawberries with graham cracker crumbs for a crunchy finish.
Arrange the filled strawberries on a serving platter and garnish with mint leaves if desired. Chill in the refrigerator for at least 30 minutes before serving for the best flavor.
