Crush the Oreo cookies into fine crumbs.
Mix the crushed Oreos with softened cream cheese until well combined.
Use a cookie scoop to portion out the mixture and roll it into balls.
Place the rolled balls on a baking sheet lined with parchment paper.
Chill the Oreo balls in the refrigerator for at least 30 minutes.
Melt the semi-sweet chocolate in a microwave-safe bowl.
Dip each ball into the melted chocolate using a fork.
Place the chocolate-covered balls back on the parchment paper.
Sprinkle with toppings while the chocolate is still wet.
Refrigerate until the chocolate is set.
