Line your baking dish (9x9 or 9x13 inches) with parchment paper and lightly coat with cooking spray, if desired.

Place red candy melts and coconut oil in a microwave-safe bowl. Microwave in 30-second increments, stirring between each increment until melted and smooth.

Pour red melted candy into the prepared baking dish and spread it out evenly. 

Sprinkle the OREO cookies and sprinkles over the melted candy, then place in the fridge for about an hour.

Remove from the fridge then remove parchment paper from the pan, dropping the parchment paper onto the counter a couple of times to break the bark up. Then serve and enjoy!
