In a microwave-safe bowl, add white chocolate melting wafers and paramount crystals¹. Microwave on medium heat for 30 seconds. Remove and stir slowly. Replace in microwave for 15-second increments until candy wafers are completely melted.
Dip Oreo cookies into melted white chocolate using a fork or dipping tool and lightly tap to remove excess white chocolate; transfer to a lined baking sheet and immediately add royal icing eyes. Allow Halloween Mummy Oreo Cookies to sit until chocolate hardens.
Pour melted chocolate into a decorating bag or sandwich bag and snip a wee-bit of the corner off. Pipe lines back and forth over the cookies to resemble a mummy; be careful not to cover the eyes. Allow Halloween Mummy Oreo Cookies to sit until chocolate hardens. Eat & Enjoy!
Notes
Halloween Mummy Oreo Cookies should be stored in an airtight container and will keep 7+ days.¹ Optional: Paramount crystals help keep chocolate shiny and smooth, as well as alleviate sugar bloom and fat bloom. You do not need them, but they are recommended.
