Line an 8-by-12-inch/20-by-30-centimeter pan with parchment paper, leaving an overhang on the sides for easy removal.
Place the crushed biscuits in a large bowl.
Combine the white chocolate, butter, and cream in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until melted and smooth.
Pour the chocolate mixture over the biscuits and stir until evenly combined. Add the cheese and mix until incorporated.
Transfer the mixture to the prepared pan. Press firmly into an even layer.
Pour the melted Lotus cookie butter over the top and spread evenly.
Freeze until firm, about 2 hours.
Remove from the pan and cut into squares.
Store in the freezer and serve cold.
