In a food processor, add the Oreos and pulse into crumbs. Add the cream cheese and mix until combined. Using a cookie scoop or a spoon, scoop out tablespoon sized balls. Roll balls in your hands, place on a silicone mat or parchment paper lined sheet tray that will fit in your freezer.
Let freeze overnight or at least 3 hours until frozen solid. Doing a few at a time, dip the truffles in the almond bark per instructions in the blog post.
Add a drizzle of melted candy on top of each truffle, immediately add M&Ms for decoration, this is optional. You can also use more crushed up Oreos, sprinkles, or a drizzle of dark chocolate if you wish.
