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.
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.
