Take a mixing bowl, add in the cream and then the icing sugar followed by the condensed milk and vanilla extract. Mix all these till little creamy and fluffy ( please do not over mix, say do this only for few seconds ).
Crush all the Oreo cookies in a ziplock bag unevenly (some small and some big chunks).
Add the crushed cookies into the same bowl at the end. Now mix everything together and pour it in the container, top it with few crushed Oreo cookies bits and keep it in the freezer!
There is no need to take it out and stir it repeatedly either.
Keep it in the freezer overnight or for approx 6 -8 hours before you serve it.
