First chop up the Oreo cookies really small. You can best use a food processor or otherwise slam them with a rolling pin. You know the drill..
Melt the butter and pour it over the cookies.
Prepare a baking tin by greasing the bottom and the sides. Pour in the cookie/butter-mixture. Press it hard against the bottom with a glass and place it in the fridge.
Whip up the whipped cream and sugar until it's stiff.
In a small bowl, whisk the cream cheese so it becomes a bit more fluffy. Add it to the whipped cream and whip it up again.
Melt the dark chocolate au-bain marie and pour it slowely in the cream cheese-mixture. Fold it through with a spatula until it's thoroughly mixed.
Pour your chocolate cream cheese on top of the crust and decorate it with some left over Oreo cookies or chocolate shavings. Let the cake set in the fridge for at least a couple of hours but best for a whole night.Enjoy!
