01 - Line the base of a 9-inch springform pan with parchment paper.
02 - In a bowl, mix crushed biscuits with melted butter until evenly moistened. Press firmly into the bottom of the pan to create an even layer. Refrigerate until needed.
03 - Gently melt white chocolate in a heatproof bowl set over simmering water. Cool slightly.
04 - In a large bowl, beat cream cheese together with granulated sugar until smooth. Incorporate vanilla extract and lemon juice, blending thoroughly.
05 - In a separate bowl, whip heavy cream to medium-stiff peaks.
06 - Fold melted white chocolate into the cream cheese mixture, then gently fold in whipped cream until just combined and smooth.
07 - Pour the filling over the prepared crust. Smooth the top, cover, and refrigerate for at least 6 hours, or overnight for best texture.
08 - Combine cranberries, sugar, and water in a saucepan. Cook over medium heat until cranberries burst and the mixture thickens, about 8 minutes. Stir in cornstarch slurry and cook for 1–2 minutes until glossy and slightly thickened. Cool completely.
09 - Spread the cooled cranberry topping over the set cheesecake immediately before serving.
