Process Oreos to crumbs in a food processor. Transfer to a medium bowl and mix in softened cream cheese (hands work best!). Roll into 24 balls, placing them on a wax paper-lined rimmed baking sheet. Freeze until solid, at least one hour or up to several days ahead.
Meanwhile melt chocolate in a medium heatproof bowl set over a pan of simmering water (or microwave if you like). Working a few at a time, dip balls in the chocolate, rolling around to coat all sides; remove with a slotted spoon and return them to baking sheet. Sprinkle with decorations and refrigerate until set. Enjoy!
