In a mixing bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix well until all crumbs are evenly coated.
Press the mixture firmly into the bottom of a 9-inch springform pan to create an even layer. Set aside.
In another bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add the powdered sugar and vanilla extract, mixing until well combined.
In a separate bowl, whisk the heavy whipping cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture using a rubber spatula until no streaks remain.
Pour the cheesecake filling over the prepared crust, smoothing the top with the spatula. Refrigerate for a minimum of 4 hours, or overnight for best results.
Before serving, top the cheesecake with mixed berries. If desired, brush with fruit glaze to add a shiny finish.
Slice into wedges and serve chilled.
