Line a baking sheet with wax paper and set aside. Add the Oreos and softened cream cheese cubes to a food processor and pulse on high until smooth.

Arrange the Reese's mini cups on wax paper, wide end down, and spray them with the color mist. Let the mist set. When 5 minutes remain of the chill time, heat the almond bark and candy melts in separate microwave-safe bowls, one at a time.

Store the Oreo balls in a flat layer in an airtight container. Then store them in the fridge to enjoy for up to 2 weeks. If needed, you can store them in layers with parchment paper separating them. This way, the truffles don’t stick together and potentially mess up the decorations.
