Mix Oreo crumbs with softened cream cheese and peppermint extract until fully combined.
Roll mixture into small balls and place on a parchment-lined pan.
Chill until firm.
Melt white chocolate or almond bark.
Dip chilled truffles in melted coating and place back on parchment.
Sprinkle with crushed candy canes before coating sets.
Chill until firm before serving.
Notes
Chill the Oreo balls before dipping so they hold their shape. Use peppermint extract lightly because too much can overpower the chocolate. Store refrigerated for up to 1 week or freeze for make-ahead holiday trays. Let frozen truffles thaw in the refrigerator.
