Take a large rimmed baking sheet. Cover it with waxed paper.
Take a bowl. Add the softened cream cheese and finely crushed Oreo Cookies. Mix until well-combined.
Make 48 1-inch balls out of the cream cheese mixture.
One at a time, roll the cream cheese balls in the powdered sugar until the balls are evenly coated on all corners.
Place the balls, in a single layer, on the baking sheet.
Refrigerate the balls for an hour or until firm. Snowball Oreo Cookie Balls are ready! Enjoy, and remember to put the leftover cookie balls in the fridge.
