01 - Combine crushed biscuits with melted butter in a mixing bowl. Press mixture evenly into the base of a 9-inch springform pan lined with parchment paper. Refrigerate while preparing the filling.
02 - Place cranberries, granulated sugar, water, and lemon juice in a small saucepan over medium heat. Simmer for 8 to 10 minutes, stirring occasionally, until cranberries burst and mixture thickens. Allow to cool to room temperature, then optionally puree until smooth.
03 - Set chopped white chocolate in a heatproof bowl over a pot of barely simmering water (double boiler) and stir until melted and smooth. Let cool slightly.
04 - In a large bowl, beat softened cream cheese and powdered sugar until silky and lump-free. Incorporate vanilla extract and the melted white chocolate, mixing thoroughly.
05 - In a separate bowl, whip cold heavy cream to stiff peaks. Fold whipped cream gently into the cream cheese mixture until homogenous and airy.
06 - Spread half of the cheesecake filling over the chilled crust. Spoon half of the cranberry sauce on top and swirl gently with a knife or skewer. Repeat layering with remaining filling and cranberry sauce to achieve a marbled look.
07 - Cover pan with plastic wrap or foil and refrigerate for at least 6 hours or overnight until firmly set.
08 - Before serving, garnish with white chocolate shavings, fresh cranberries, and mint leaves as desired. Release cheesecake from the springform pan and cut into portions.
