Add the sandwich cookies to a food processor and blend until they reach a fine crumb consistency.
Transfer the cookie crumbs to a large mixing bowl. Add the softened cream cheese and stir until a thick, uniform mixture forms with no dry crumbs remaining.
Line a baking tray or plate with parchment paper.
Scoop approximately 1 tablespoon of the mixture and roll into smooth balls. Arrange them on the prepared tray.
Refrigerate the cookie balls for at least 30 minutes, or until firm enough to handle easily.
Place the chocolate and coconut oil, if using, into a microwave-safe bowl. Heat in short intervals, stirring frequently, until completely melted and silky smooth.
Remove the chilled balls from the refrigerator. Using a fork or dipping tool, coat each ball in the melted chocolate, allowing any excess to drip off.
Return the coated balls to the parchment-lined tray.
Before the chocolate hardens, decorate with crushed cookies, sprinkles, or a drizzle of melted white chocolate.
Let the coating set completely. For faster results, refrigerate for 10 to 15 minutes.
Serve chilled or allow them to sit briefly at room temperature before enjoying.
