01 - Line the base of a 9-inch springform pan with parchment paper.
02 - In a mixing bowl, combine the crushed graham crackers and melted butter until the mixture is evenly moistened. Press firmly into the bottom of the pan to create an even crust layer. Refrigerate while preparing the filling.
03 - Set a heatproof bowl over gently simmering water and melt the chopped white chocolate, stirring until smooth. Remove from heat and let cool slightly.
04 - In a large bowl, beat the cream cheese with the sugar until smooth. Mix in the vanilla extract and lemon juice until fully incorporated.
05 - In a separate bowl, whip the heavy cream using a hand mixer or stand mixer until medium-stiff peaks form.
06 - Gently fold the melted white chocolate into the cream cheese mixture. Then fold in the whipped cream until just combined, taking care not to deflate the mixture.
07 - Pour the filling over the chilled crust and smooth the surface using a spatula. Cover and refrigerate for at least 6 hours, or overnight for best texture.
08 - In a saucepan, combine cranberries, sugar, and water. Cook over medium heat until the cranberries burst and the mixture thickens, about 8 minutes. Stir in cornstarch slurry and cook 1–2 minutes more, until glossy and slightly thickened. Cool completely.
09 - Spread the cooled cranberry topping over the set cheesecake immediately before serving.
