Crush the Oreos: use a food processor to turn Oreo cookies into a fine crumb. Alternatively, place the cookies in a ziplock bag and use a rolling pin to crush the cookies. Optional: reserve 1-2 tablespoons of crushed Oreos for garnish.
Mix with cream cheese: add cream cheese to the food processor and process until smooth. If you do not have a food processor: in a large bowl, combine the crushed Oreos with softened cream cheese and mix with a hand mixer until smooth and blended.
Roll into balls: use one tablespoon of Oreo ball mix and roll into balls. Place them on a parchment lined baking sheet. You will get about 25-30 Oreo balls.
Freeze: place the Oreo balls in the freezer for 15-20 minutes, or in the refrigerator for about an hour to firm up.
Dip: melt almond bark, chocolate chips, or candy melts according to package directions. Dip each ball in the melted chocolate. Use two forks to help evenly coat the truffles.
Decorate: immediately add sprinkles or reserved Oreo cookie crumbs to the dipped Oreo ball before the chocolate sets.
Chill: Allow the Oreo balls to chill in the refrigerator for about 30 minutes, then serve.
