Separate the Oreos, preparing the cream and cookies individually.
Place the cookies in a bag and crush them into small pieces.
Add sugar to heavy cream and whip it.
In a sealed container, layer the crushed Oreos and whipped cream alternately.
Smooth the top, cover with plastic wrap, and let it chill in the refrigerator for at least 4 hours.
Cut into appropriate sizes and serve on a plate.
