Ice Cream Cheesecake Filling
Beat cream cheese powdered sugar and vanilla until smooth and lump free
stir in softened ice cream until uniform then fold in whipped topping until no streaks remain
fold in chopped Oreos.
Assemble And Freeze
Spread filling over cooled crust and smooth the top then cover and freeze until firm at least 6 hours or overnight
let stand 10 to 15 minutes at room temperature before slicing then top with whipped topping crushed Oreos and chocolate syrup.
Notes
1. Use full fat cream cheese for best texture. Soften ice cream just until stirrable to avoid a runny filling. Swap cookies and cream ice cream for vanilla plus extra crushed Oreos. For cleaner slices dip the knife in hot water and wipe between cuts
