Process the 36 Oreo cookies in a food processor/blender until they are crumbs. If you do not have one, put them in a plastic bag and smash them with a wooden spoon or other utensil. Add the cream cheese and process until combined.
Use a cookie scoop or spoon to make the Oreo balls, put them on a pan with parchment paper, and then stick them in the freezer for 15 minutes. This will make them firm enough so you can roll them into a perfect ball with your hands without sticking.
After the 15 minutes, roll them into balls in between your hands. Place them back in the freezer while you melt your chocolate. Melt chocolate of choice on the stovetop or in 15 second intervals in the microwave. Once completely melted, toss the Oreo balls in the chocolate making sure they are completely covered and place back on the baking sheet. Sprinkle desired toppings on and freeze for 20 minutes or until chocolate has set. Enjoy!
