01 - Line the base of a 9-inch springform pan with parchment paper.
02 - Thoroughly combine the crushed biscuits and melted butter in a bowl until texture is like wet sand. Press firmly into the bottom of the prepared pan to form an even crust. Refrigerate while preparing the filling.
03 - Gently melt the white chocolate in a heatproof bowl set over a saucepan of simmering water, stirring until smooth. Let cool slightly before using.
04 - In a large mixing bowl, beat the cream cheese and sugar with a mixer on medium speed until silky and smooth. Add vanilla extract and lemon juice; continue beating until fully incorporated.
05 - Whip the heavy cream in a separate bowl until medium-stiff peaks form.
06 - Fold the melted white chocolate into the cream cheese mixture until blended. Gently fold in the whipped cream, ensuring the mixture remains light and airy.
07 - Spread the cheese filling evenly over the chilled crust. Smooth the surface. Cover and refrigerate for at least 6 hours or overnight until fully set.
08 - Combine cranberries, sugar, and water in a saucepan over medium heat. Cook for about 8 minutes, stirring occasionally, until the cranberries burst and the mixture thickens. Stir in the cornstarch slurry; cook for 1 to 2 minutes more until glossy and slightly thickened. Let the topping cool completely.
09 - Spread the cooled cranberry topping over the set cheesecake just before serving.
