Start by placing your Oreo cookies into a food processor. Pulse until they are finely crumbled, resembling sand, which should take about 1-2 minutes.

In a mixing bowl, add the crumbled Oreo cookies and your softened cream cheese. Using a hand mixer, blend them together on medium speed for about 2-3 minutes.

Using your hands, scoop out tablespoon-sized portions of the mixture and roll them into 1-inch balls. Place each ball on a parchment-lined baking sheet.

Once all the balls are shaped, pop the baking sheet into the freezer. Chill for about 30 minutes, or until they are firm to the touch.

While the balls are chilling, take a microwave-safe bowl and add your melting chocolate. Heat it in the microwave at medium power for 30 seconds, then stir.

Retrieve the chilled Oreo balls from the freezer. One by one, dip each ball into the melted chocolate using a fork, ensuring it's fully coated.

While the chocolate coating is still wet, sprinkle your desired festive toppings generously over each ball.

After decorating, return the baking sheet to the freezer and let the Halloween Oreo Balls chill for at least another hour.
