01 - Line the bottom of a 9-inch springform pan with parchment paper to facilitate easy removal.
02 - Blend the crushed biscuits with melted butter until uniformly incorporated. Press mixture firmly into the base of the prepared pan to create an even layer. Refrigerate while preparing the filling.
03 - Gently melt white chocolate in a heatproof bowl set over a pan of simmering water. Stir until smooth and allow to cool slightly before using.
04 - Using a mixer, beat cream cheese with granulated sugar until smooth and fluffy. Add vanilla extract and lemon juice, blending thoroughly.
05 - Whip heavy cream to medium-stiff peaks in a separate bowl.
06 - Fold cooled melted white chocolate into the cream cheese mixture. Gently incorporate whipped cream until fully combined, taking care to maintain volume.
07 - Pour the filling onto the chilled crust. Smooth the surface with a spatula. Cover and refrigerate for at least 6 hours, or overnight for optimal texture.
08 - In a saucepan, combine cranberries, sugar, and water. Cook over medium heat, stirring occasionally, until cranberries burst and the mixture thickens, approximately 8 minutes. Stir in cornstarch slurry, continue cooking 1–2 minutes until glossy and slightly thickened. Cool completely.
09 - Spread the cooled cranberry topping evenly over the chilled cheesecake just before serving. Optionally, garnish with white chocolate shavings or fresh cranberries.
