Prepare your cake mix according to the package instructions and let it cool completely.

In a large mixing bowl, combine the crushed Oreos and cream cheese, mixing until well combined.

Scoop the Oreo mixture using a tablespoon-sized cookie scoop and roll into balls.

Arrange the balls on a parchment paper-lined baking sheet, covering them with plastic wrap. Refrigerate for at least 1 hour.

Melt the chocolate in a microwave-safe bowl, heating in 30-second intervals, stirring until smooth.

Dip each chilled ball into the melted chocolate using a skewer or fork, then place back on parchment paper.

Top with optional Oreo crumbs or sprinkles immediately after coating.

Chill the dipped balls for another hour until set in the refrigerator.
