01 - Line the base of a 9-inch springform pan with parchment paper.
02 - Combine crushed biscuits and melted butter in a mixing bowl until the mixture is evenly moistened. Press firmly into the bottom of the prepared pan to form an even crust. Refrigerate while preparing the filling.
03 - Gently melt white chocolate in a heatproof bowl set over simmering water, stirring occasionally until smooth. Remove from heat and allow to cool slightly.
04 - In a large mixing bowl, beat the cream cheese and granulated sugar until completely smooth. Add vanilla extract and lemon juice, mixing until fully combined.
05 - In a separate bowl, whip the heavy cream using a hand or stand mixer until medium-stiff peaks form.
06 - Fold the melted white chocolate into the cream cheese mixture until evenly incorporated. Gently fold in the whipped cream, taking care not to deflate the mixture.
07 - Pour the prepared filling over the chilled crust, spreading smoothly. Cover lightly and refrigerate for at least 6 hours, or overnight for optimal texture.
08 - Place cranberries, granulated sugar, and water in a saucepan over medium heat. Cook, stirring, until cranberries burst and mixture thickens, about 8 minutes. Stir in the cornstarch slurry and continue cooking 1–2 minutes until topping is glossy and slightly thickened. Allow to cool completely.
09 - Spread cooled cranberry topping evenly over the set cheesecake just before serving.
