Begin by placing the Oreo cookies in a food processor and pulse until they become fine crumbs, resembling sand.
Transfer the crushed cookies into a mixing bowl, then add the softened cream cheese. Use a spatula or mixer to blend until the mixture is entirely smooth and there are no visible chunks of cream cheese.
Incorporate the peppermint extract along with a pinch of salt into the mixture, stirring until well combined to enhance the flavor profile.
With clean hands, scoop out portions of the mixture and roll them into balls about 1 inch in diameter. Arrange these balls on a parchment-lined baking sheet for easy removal.
Place the baking sheet in the freezer and allow the truffles to chill for approximately 30 minutes, or until they feel firm to the touch.
While the truffles are chilling, prepare the white chocolate coating. In a microwave-safe bowl, add the white chocolate chips and melt them in 30-second intervals, stirring in between each interval until completely smooth and fluid.
Once the truffles are firm, retrieve them from the freezer. Use a fork to dip each truffle into the melted white chocolate, making sure to coat it thoroughly. Let any excess chocolate drip off before setting it back onto the parchment-lined baking sheet.
Immediately sprinkle the crushed peppermint candies over the top of each chocolate-coated truffle before the coating sets, ensuring each truffle is decorated beautifully.
Allow the truffles to sit at room temperature until the white chocolate hardens slightly, then refrigerate them for at least 15 minutes to firm up completely before serving.
Notes
Arrange your delightful truffles on a festive platter or place them individually in decorative paper cups.
