Melt the chocolate with a double boiler or in a microwave.
Remove the cream from the oreo. Break the biscuits into small pieces.
Put the cold whipped cream, condensed milk and pure chocolate powder in a big mixing bowl. Use a hand mixer to beat on low speed for 1 min. Then change to high speed and beat it until stiff peak formed.
Add the melted chocolate and oreo to the mixture. Fold it in until just mixed.
Put the mixture in a container that can put in the freezer. Then leave it in the freezer overnight. Enjoy it the next day with your favorite toppings!
