Preheat the oven to 350°F and line a large baking sheet with parchment paper. Pull the Oreos apart and place the non-cream sides flat side up on the baking sheet. Set the cream sides aside.

Once set, melt the melted wafers in a wide and deep glass or bowl at 30-second intervals, stirring between each one, until fully melted. Dip half of each of the Oreos in the chocolate and place back on the parchment line baking sheet. Sprinkle with sea salt and sprinkles if desired and let cool until hardened.

When stored in an airtight container in the refrigerator or at room temperature the cookies will keep for up to 2 weeks.
