01 - Line a baking sheet with parchment paper for easy cleanup and transfer.
02 - Process Oreo cookies in a food processor until reduced to fine, uniform crumbs.
03 - Add softened cream cheese to the crumbs and blend until completely incorporated, forming a thick, pliable dough.
04 - Scoop 1-tablespoon portions and roll between palms into smooth rounds. Arrange on the prepared baking sheet.
05 - Freeze the formed balls for 20-30 minutes until firm enough to handle without losing shape.
06 - Melt white chocolate or candy melts in a microwave-safe bowl, stirring at 30-second intervals until completely smooth.
07 - Submerge each chilled ball in melted chocolate, lift with a fork allowing excess to drip away, and return to the baking sheet.
08 - While coating remains tacky, attach marshmallow ears dipped in pink sugar, chocolate chip eyes, heart sprinkle noses, and marshmallow tails.
09 - Refrigerate decorated balls for at least 30 minutes until chocolate coating is fully hardened and stable.
