Put Oreos in a food processor and grind up until sand-like.

Mix Oreos with softened cream cheese using a spatula or your hands until well-combined.

Scoop out Oreo mixture into balls, forming whatever size you like (easy to do so with an ice cream or cookie scoop!)

Melt white chocolate. Stick a fork or skewer into Oreo balls and dip Oreo balls into white chocolate. Use a spoon to help drizzle white chocolate onto Oreo balls.

Let truffles rest on a cooling rack. Sprinkle on toppings while chocolate is still melted. Cool until chocolate hardens.
