Line a baking sheet with a piece of wax paper. This will provide you with a surface to place the dipped cookies on so they can harden properly before serving.
In a small microwave-safe bowl, melt the white melting candies. Heat them in the microwave in 30-second intervals at 50% power, stirring between each interval to promote even melting. This process should take about 4-5 minutes. Be careful not to overheat or burn the candy melts. I like to keep an eye on them and stir a little extra to ensure they stay silky smooth.
Hold each Nutter Butter sandwich cookie and dip it into the melted white candies, covering about 70-75% of the cookie so that the bottom remains exposed. Allow excess candy coating to drip off, gently tapping the cookie against the side of the bowl if needed.
While the white candy coating is still wet, press two decorative candy eyes and one mini semi-sweet chocolate chip onto the upper coated part of each cookie to create a ghost face.
Place each decorated cookie onto the wax-paper-lined baking sheet. Let the cookies set for 5-10 minutes, allowing the candy coating to harden before serving. This brief wait ensures the decorations stay in place and gives you perfectly set treats ready to enjoy!
