Place the Oreo cookies in the bowl of a food processor and pulse until finely ground.
Add the cream cheese and pulse until the mixture is well combined and smooth.
Line a rimmed baking sheet with parchment paper.
Scoop the mixture into balls about 1-inch in diameter. I like to use cookie scoop.
Place the cookie balls in the freezer until well chilled, at least 1 hour.
Remove truffles from freezer and dip in melted chocolate chips.
Garnish with reserved Oreo crumbs before the chocolate sets up.
Let chocolate set, refrigerate and enjoy!
