Crush the Oreos: Add the Oreo cookies to a food processor and pulse until they become fine crumbs.
Mix with cream cheese: Add the softened cream cheese and process until the mixture is thoroughly combined and forms a thick dough.
Form the truffles: Scoop the mixture into approximately 24 equal portions and roll each portion between your hands to form smooth balls.
Chill: Place the Oreo balls on a parchment-lined baking sheet and refrigerate for at least 30 minutes to firm them up.
Melt the chocolate: Melt the chocolate according to the package directions. If needed, stir in a small amount of shortening or coconut oil to make the chocolate easier to dip.
Dip the Oreo balls: Using a fork or dipping tool, dip each chilled Oreo ball into the melted chocolate, allowing the excess chocolate to drip back into the bowl.
Decorate: Place the coated truffles back on the parchment paper. While the chocolate is still wet, sprinkle with crushed Oreo cookies or drizzle with additional melted chocolate.
