In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until well combined. Press the mixture evenly into the bottom of serving cups or small jars to form the crust.
In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until fully incorporated.
In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until well combined.
Spoon the cheesecake filling over the graham cracker crust in each cup, filling them about three-quarters full.
Top the cheesecake with a layer of diced strawberries and blueberries, creating a patriotic red, white, and blue effect.
Refrigerate the cups for at least 2 hours to allow them to set before serving.
