Line a baking tray with parchment and set it aside. Blend the Oreo cookies into fine crumbs using a food processor or blender.
In a large mixing bowl with a hand mixer on high speed, beat the softened cream cheese until smooth. Add the Oreo crumbs and mix together until well combined.
Using a 1.5” cookie scoop, make even sized balls and roll it together in the palms or your hands until smooth. Place onto the prepared baking tray and refrigerate for 2 hours. Chilling the balls will help them keep their shape when dipping into the melts.
Set aside ½-¾ cup of the light green candy melt pieces to use later for drizzle if desired. Prepare a double boiler over low heat or use a candy melting pot and melt the remaining light green wafers until smooth. Stir every minute to ensure it is heating evenly.
Dip each ball one at a time into the melts and remove it with a fork. Tap the fork on the edge of the double boiler or pot to remove any excess coating. Place onto the prepared baking tray and repeat with the rest of the balls.
Place ½ cup of the set aside candy melts into a microwave safe piping bag, twist it shut, and melt it in the microwave on a low or defrost setting until fully melted and smooth. Massage the bag every 2 minutes to ensure it is melting evenly.
Snip a small piece of the tip off of the piping bag and drizzle over the coated balls, four at a time. Immediately top with a red heart sprinkle before the drizzle sets completely.
Allow the coating to fully set before serving. You can place them in the refrigerator to help them harden faster. Enjoy!
