Combine Oreos and Cream Cheese: In a large mixing bowl, combine the finely crushed Oreo cookies with softened cream cheese. Mix until the mixture becomes smooth and dough-like. A food processor can make this step easier by crushing and blending everything quickly.

Form the Balls: Scoop about one tablespoon of the Oreo mixture and roll it into a small ball between your palms. Place each ball on a parchment-lined baking sheet, spacing them out slightly.

Chill the Oreo Balls: Place the tray in the refrigerator and let the Oreo balls chill for about 30 minutes. Chilling helps firm them up, making them easier to dip in chocolate.

Dip in Chocolate: Using a fork or dipping tool, dip each Oreo ball in melted white chocolate or milk/dark chocolate. Lift each ball, allowing the excess chocolate to drip back into the bowl, then place back on the parchment paper.

Decorate with Sprinkles: Before the chocolate hardens, sprinkle each Oreo ball with red and green sprinkles or drizzle with colored icing for a festive Christmas look.

Set the Chocolate: Allow the chocolate coating to firm up at room temperature, or place the tray back in the fridge to speed up the process.

Serve and Store: Store Oreo balls in an airtight container in the refrigerator and serve them chilled.
