In a small bowl, combine cream cheese and nutella. Mix thoroughly.
Using a electric mixer, whip the cream until stiff peaks form. Reserve ¼cup of the whipped cream for topping the cheesecake.
In the remaining whipped cream, add the cream cheese - nutella mixture and beat until well combined.
To Assemble: Divide the crushed oreos evenly between the serving cups/ glasses and press it lightly to form a crust in the bottom.
Spoon or pipe the nutella-cream cheese filling over the oreo crust. Then top it with the reserved whipped cream and sprinkle crushed nuts or oreos.
Chill for at least 2 hours to set the cheesecake. Serve cold and enjoy!!
