01 - Line the base of a 9-inch springform pan with parchment paper to ensure easy release.
02 - In a mixing bowl, combine the crushed graham crackers with melted butter and stir until thoroughly moistened. Press the mixture firmly into the bottom of the prepared pan to create an even crust. Refrigerate to set while preparing the filling.
03 - Place chopped white chocolate in a heatproof bowl over a pot of gently simmering water. Stir until melted and smooth, then remove from heat and allow to cool slightly.
04 - In a large bowl, beat together the cream cheese and sugar until smooth and creamy. Mix in the vanilla extract and lemon juice until fully incorporated.
05 - In a separate bowl, whip the heavy cream with a hand or stand mixer until medium-stiff peaks form.
06 - Fold the cooled, melted white chocolate into the cream cheese mixture. Gently fold in the whipped cream until the mixture is just combined and smooth.
07 - Pour the filling over the chilled crust, smooth the top with a spatula, cover, and refrigerate for at least 6 hours or overnight until set.
08 - In a saucepan, combine cranberries, sugar, and water. Cook over medium heat until cranberries burst and the mixture thickens, about 8 minutes. Stir in the cornstarch slurry and cook 1–2 minutes longer, until glossy and slightly thickened. Let cool completely.
09 - Once the cheesecake is fully set, spread the cooled cranberry topping evenly over the surface just before serving.
