Process oreo in food processor for 1 minutes (make sure you can still see a chunk in it, you don't want to make it like a flour)

Mix heavy whipping cream and condensed milk in an electric mixer and beat until foam

Add rhum in cream mixture (if you like)

In a cup, place oreo cookies crumble as a first layer, then add the cream as the second layer. Repeat until you have 4 layers

Put in freezer for 2 hours and enjoy the yummiest creamy desserts.
