In a medium bowl, combine the melted butter, graham cracker crumbs, and granulated sugar. Mix until the crumbs are well coated. Press the mixture firmly into the bottom of a 9-inch springform pan to create an even layer. Place the crust in the refrigerator to set while you prepare the filling.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add in the granulated sugar and confectioners sugar, mixing until well combined.
Mix in the vanilla extract and freshly squeezed lemon juice. The lemon will add a lovely brightness to the cheesecake.
In a separate bowl, whip the cold heavy whipping cream until stiff peaks form. This step is crucial for achieving that light and airy texture in your cheesecake.
Gently fold the whipped cream into the cream cheese mixture. Be careful not to deflate the whipped cream—this is what gives your cheesecake its fluffy texture.
Pour the cheesecake filling over the chilled crust, smoothing the top with a spatula. Cover the cheesecake with plastic wrap and refrigerate for at least 4 hours, or overnight for the best results.
Once set, carefully remove the sides of the springform pan. Slice the cheesecake and serve it plain or topped with your favorite fruits, chocolate sauce, or even a drizzle of caramel.
