Begin by placing your chocolate sandwich cookies (Oreos) in a food processor. Pulse until they transform into fine crumbs, about 30–45 seconds.

In a mixing bowl, combine the crushed Oreos with softened cream cheese. Use a spatula or your hands to blend until the mixture is smooth and well incorporated, which should take about 2 minutes.

Scoop out about 1 tablespoon of the mixture and roll it into a 1-inch ball. Place the formed balls on a baking sheet lined with parchment paper and refrigerate for 1 hour.

While your cookie balls chill, twist apart additional chocolate sandwich cookies to create the bat wings.

Melt your chocolate according to package instructions, and dip each cookie ball into the melted chocolate to coat.

Attach the Oreo halves as wings to each dipped cookie ball before the chocolate coating hardens.

Use the melted chocolate to attach mini chocolate chips as eyes and ears on the bat.

Let the decorated cookie balls sit at room temperature for about 30 minutes to set the chocolate.
