In a medium bowl, combine graham cracker crumbs, granulated sugar, and melted butter. Mix until well combined.
Press the mixture firmly into the bottom of a mini muffin tin to form the crust. Chill in the refrigerator for 30 minutes.
In another bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
In a separate bowl, whip the heavy cream until stiff peaks form.
Gently fold the whipped cream into the cream cheese mixture until fully combined.
Remove the crust from the refrigerator and spoon the cheesecake filling on top of each crust, filling them to the top. Smooth the surface with a spatula.
Refrigerate for at least 2 hours to set.
Once set, top each cheesecake bite with sliced strawberries and blueberries for a festive touch. Serve chilled.
