01 - Line a baking sheet with parchment paper and set aside for later use.
02 - Process Oreo cookies in a food processor until reduced to fine crumbs.
03 - Add softened cream cheese to the crumbs and blend until completely combined, forming a thick, uniform dough.
04 - Scoop tablespoon-sized portions and roll into smooth balls. Arrange evenly on the prepared baking sheet.
05 - Freeze the shaped balls for 20 to 30 minutes until firm enough to handle for dipping.
06 - Place white chocolate or candy melts in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely smooth.
07 - Dip each chilled ball into melted chocolate using a fork. Lift and allow excess coating to drip off before returning to the baking sheet.
08 - Working quickly before chocolate sets, cut mini marshmallows diagonally for ears. Dip cut edges in pink sugar or gel and press onto the top of each ball. Add chocolate chip eyes, heart sprinkle noses, and mini marshmallow tails.
09 - Refrigerate decorated bunny balls for at least 30 minutes until coating is completely set. Store chilled until ready to serve.
