Begin by crushing the Oreo cookies into fine crumbs using a food processor or by placing them in a zip-top bag and crushing them with a rolling pin.

In a mixing bowl, combine the crushed Oreo crumbs with softened cream cheese and blend until a moldable mixture forms.

Roll the mixture into 1-inch balls and place them on a parchment-lined baking sheet.

Chill the baking sheet with the rolled Oreo balls in the freezer for about 30 minutes until firm.

Melt the black chocolate melts according to package instructions in a microwave-safe bowl.

Once firm, insert popsicle sticks into each ball and dip into the melted black chocolate, letting excess chocolate drip off.

Before the chocolate sets, pipe Jack's facial features with white chocolate melts and sprinkle with Halloween-themed decorative sprinkles.
