01 - Line a baking sheet with parchment paper and set aside.
02 - Place Oreo cookies in a food processor and pulse until reduced to fine crumbs.
03 - Add softened cream cheese to the crumbs and process until completely incorporated and a thick, uniform dough forms.
04 - Scoop out tablespoon-sized portions and roll into smooth balls. Arrange on the prepared baking sheet.
05 - Place the baking sheet in the freezer for 20 to 30 minutes until balls are firm to the touch.
06 - Microwave white chocolate or candy melts in a microwave-safe bowl, stirring every 30 seconds until completely smooth.
07 - Dip each chilled ball into the melted chocolate, using a fork to lift and allowing excess to drip off. Return to the baking sheet.
08 - While coating is still soft, cut mini marshmallows diagonally, dip cut side in pink sugar or gel, and press onto top for ears. Attach chocolate chips as eyes, heart sprinkles or M&M minis as noses, and mini marshmallows as tails.
09 - Refrigerate decorated balls for at least 30 minutes until chocolate coating is fully set.
