Prepare the crust by mixing graham cracker crumbs, melted butter, and granulated sugar. Press into the bottom of a 9-inch springform pan and refrigerate for 30 minutes.
Make the cheesecake filling by beating softened cream cheese until smooth. Gradually add powdered sugar and vanilla extract, mixing until fully incorporated.
Whip heavy cream until stiff peaks form and gently fold into the cream cheese mixture. Pour over the chilled crust and smooth the top. Cover and refrigerate for at least 4 hours or overnight.
After chilling, remove the sides of the springform pan, slice, and serve chilled. Optionally, top with fresh fruit, chocolate sauce, or whipped cream.
