Prepare a parchment paper lined baking sheet, set aside.
Add the Oreos to your food process. Process until crushed into fine crumbs.
To a large bowl, add the crushed cookies and cream cheese. Stir until well combined.
Separate the cookie mixture into three separate small bowls.
Add 2-3 drops of food dye to each bowl, making one green bowl, one purple and one orange. Stir each well until the color is fully distributed through the cake ball batter.
Using a cookie scoop, add a little bit of each color until you have about a tablespoon of batter. Roll into a ball.
Place ball on the parchment lined baking tray, allow to chill in the freezer at least 30 minutes.
Melt candy melts in a microwave safe dish in 30-second intervals until smooth and melted.
Using two forks, carefully dip each chilled cookie ball into the melted chocolate, then return to the parchment paper lined sheet pan.
Immediately top with Halloween sprinkles, candy eyes, or decor of your choice!
Notes
If you have excess chocolate, you can drizzle the chocolate coated balls with it before decorating with sprinkles.
