Add orange candy melts to a microwaveable bowl. Cook for 1 minute in the microwave at 50% power. Stir. Continue to cook at 30 second intervals (50% power), stirring in between, until candy melts are melted.
Dip Oreos in the melted mixture to completely cover. Use a spoon to hold the Oreo when you dip it in so it’s easier to maneuver.
Place Oreo on a piece of parchment paper and quickly add a jujube to the outside edge for your pumpkin stem.
Let cookies sit at room temperature until hardened (about an hour).
