Place the Oreo cookies, including the cream filling, in a food processor and pulse until fine crumbs form.
Transfer the crumbs to a large mixing bowl. Add the softened cream cheese.
Mix until the ingredients are fully combined and form a thick dough.
Scoop approximately one tablespoon of the mixture at a time and roll into small balls.
Place the balls on a parchment-lined baking sheet.
Refrigerate for about 30 minutes until firm, or freeze for 15–20 minutes.
Place the green candy melts in a microwave-safe bowl. Microwave in 20–30-second intervals, stirring between each interval until smooth.
If the coating is too thick, add ½ teaspoon of coconut oil and stir. Add a little more only if needed.
Dip each chilled Oreo ball into the melted green candy coating, turning to cover completely.
Lift each truffle with a fork or dipping tool and allow excess coating to drip off.
Place the coated truffles back onto the parchment-lined baking sheet.
Immediately add one red heart sprinkle to each truffle while the coating is still wet.
Allow the candy coating to set completely. Refrigerate for 10–15 minutes if needed.
Store in an airtight container in the refrigerator until ready to serve.
