01 - Line a baking sheet with parchment paper and set aside.
02 - Place mint Oreo cookies in a food processor and pulse until reduced to fine crumbs. Reserve 2 tablespoons of crumbs for garnish if desired.
03 - Add softened cream cheese to the cookie crumbs. Pulse until fully incorporated and mixture forms a thick, uniform dough.
04 - Roll the dough into 1-inch balls, approximately 1 tablespoon each, and arrange on the prepared baking sheet.
05 - Freeze the formed balls for 30 minutes until firm enough to handle without losing shape.
06 - Place chopped chocolate in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until completely smooth and fluid.
07 - Using two forks, dip each chilled truffle into melted chocolate, allowing excess to drip off. Return coated truffles to the baking sheet.
08 - Immediately sprinkle with reserved crushed cookie crumbs or drizzle with melted white chocolate while chocolate coating is still wet.
09 - Refrigerate truffles for at least 30 minutes until chocolate coating is completely set and firm.
10 - Serve chilled or allow to come to room temperature for 15 minutes before serving. Store in an airtight container in the refrigerator for up to 1 week.
