Begin by placing the Oreo cookies in a food processor, pulsing them into fine crumbs—this should take about 30 seconds.

In a mixing bowl, combine the Oreo crumbs with softened cream cheese. Mix thoroughly until the mixture is well blended and easily moldable.

Roll about a tablespoon of the Oreo mixture into 1-inch balls and place them on a parchment-lined baking sheet. Freeze for 30 minutes.

Melt the black chocolate melts in a microwave-safe bowl in 30-second intervals until smooth.

Remove the chilled Oreo balls from the freezer. Insert popsicle sticks into each ball, dip into the melted chocolate, and let excess chocolate drip off.

Before the chocolate hardens, decorate with Halloween-themed sprinkles or pipe facial features using melted white chocolate.
