Cover large rimmed baking sheet with parchment paper. When done, mix cream cheese and cookie crumbs until blended.
Using a 1.5 tbsp cookie scooper, shape cream cheese mixture into balls and place on the baking sheet (or on a plate). Freeze for 20-30 minutes. You can also do this step the day before and let them chill in the fridge overnight.
While the oreo balls are in the freezer, melt the candy melts in two separate bowls according to package instructions.
When the oreo balls are finished chilling, dip them in the white candy melts and place back on the parchment paper covered baking sheet. Drizzle with red melted candy and add sprinkles. Keep refrigerated until ready to serve.
Notes
To avoid the candy melts collecting at the bottom of the truffle, try placing it on a wired cooling rack overtop of the parchment lined baking sheet.
