01 - Line the base of a 9-inch springform pan with parchment paper to ensure easy removal.
02 - Mix crushed graham crackers and melted butter in a bowl until the mixture resembles damp sand. Press firmly into the bottom of the prepared pan to create an even layer. Chill in the refrigerator while assembling the filling.
03 - Gently melt chopped white chocolate in a heatproof bowl set over a saucepan of simmering water. Stir until smooth and let cool slightly.
04 - In a large mixing bowl, beat cream cheese with granulated sugar until creamy and lump-free. Blend in vanilla extract and lemon juice until fully combined.
05 - In a separate mixing bowl, whip heavy cream using a hand mixer or stand mixer until medium-stiff peaks form.
06 - Fold melted white chocolate into the cream cheese mixture, followed by the whipped cream. Gently fold until mixture is smooth and no streaks remain.
07 - Pour filling over the chilled crust. Smooth the surface with a rubber spatula, cover, and refrigerate for at least 6 hours or overnight to ensure proper setting.
08 - In a small saucepan over medium heat, combine cranberries, granulated sugar, and water. Cook until cranberries burst and mixture thickens, about 8 minutes. Stir in cornstarch slurry and cook an additional 1 to 2 minutes until glossy and slightly thickened. Allow to cool completely.
09 - Just before serving, spread the cooled cranberry topping evenly over the set cheesecake. Release and transfer to a serving plate.
