Begin by adding half of the Oreos to a food processor, half of the cream cheese cubes, the rest of the Oreos, then the rest of the cream cheese. Pulse together on high until combined and smooth, scraping down the sides of the processor as needed.
Line a baking sheet with wax paper. Using a 1-inch cookie scoop, scoop out uniform spoonfuls of the Oreo mixture. Roll each scoop into a smooth ball and place them on the lined baking sheet. Once full, put the baking sheet in the freezer for 15 minutes for the Oreo balls to firm up.
Next, lay the Reese's mini cups on wax paper with the widest end down, and spray each one with edible gold spray. Set aside.
About 3 minutes before the Oreo balls are done chilling, melt the almond bark and candy melts in separate microwave-safe bowls according to the package instructions. Set them on your counter along with the chilled Oreo balls.
Doing so one at a time, dip each of the Oreo balls into either of the chocolate barks or candy melts, covering them completely, then place them on the baking tray. Top each ball with a gold mini Reese’s and decorate with sprinkles before the chocolate hardens.
Once decorated, place them back in the refrigerator for at least 1 hour to allow the Oreo balls set completely.
