Place the Oreos in a food processor and pulse until ground into fine crumbs. You can also place the Oreos in a plastic bag and crush the by hand or with a rolling pin until the cookies are crushed into crumbs
Transfer the crushed Oreos to a large bowl, add the softened cream cheese, and mix everything until well incorporated,
With the help of a spoon, scoop a small amount of the Oreo mixture and roll it between your hand forming a small ball.
Grease a flat plate and place the Oreo ball on it. Repeat this process until you have no more of the mixture left.
Place the plate with the Oreo balls in the fridge for a minimum of 2 hours or freezer for a minimum of 40 minutes so they get very cold.
Melt the white chocolate by adding it in a small bowl, then place it in the microwave for 30 seconds, remove it from th microwave and mix the chocolate a bit, the return it to the microwave for 30 seconds more, and repeat this process until the chocolate is totally melted.
Once the Oreo balls are cold enough, remove them from the fridge or freezer, and with a fork or a skewer, carefully place each ball into the melted chocolate, let the excess chocolate drip from the Oreo balls, and place them in the previously greased plate.
Repeat this process until you coat all the balls with the melted chocolate.
Also melt the dark chocolate like you have done before, add it in a ziplock bag, cut a tiny bit of the ziplock bag tip and drizzle the dark chocolate on top of the white chocolate Oreo balls.
Put them in the fridge so the chocolate gets harder, then serve it whenever you wish!
The Oreo balls will last for up to 2 weeks in an air tight container.
