In a food processor, crush the mint-flavored Oreo cookies until they become fine crumbs.
Transfer the crushed Oreos to a mixing bowl and add the softened cream cheese.
Mix until well combined and forms a dough-like consistency.
Shape the Truffles
Using your hands, roll the Oreo mixture into small truffle-sized balls and place them on a parchment paper-lined baking sheet.
Place the truffles in the refrigerator and let them chill for a minimum of 30 minutes.
Melt the Candy Coating
In a melting pot or microwave-safe bowl, melt the green candy melts according to the package instructions.
Coat the Truffles
Dip each chilled truffle into the melted green candy coating, ensuring they are fully coated. Use a fork to lift them out, letting excess coating drip off.
Decorate the Grinch Faces
While the candy coating is still wet, place two edible candy eyes on each truffle.
Attach a red heart-shaped sprinkle just below the eyes to create the Grinch's heart.
Chill and Set
Place the decorated truffles back on the parchment paper-lined baking sheet and refrigerate until the candy coating is set.
Serve and Enjoy
Once the Grinch Oreo truffles are fully set, remove them from the refrigerator. Use a small heart-shaped cookie cutter to create a more defined heart shape around the red sprinkle.
