Begin by melting the dark cocoa candy melts in a microwave-safe bowl, heating in 30-second bursts until smooth.

Melt the salted butter in a skillet over low heat and add mini marshmallows and white chocolate chips, stirring until 75% melted.

Continue to stir until completely melted, creating a gooey blend.

Pour the melted marshmallow mixture over the Rice Krispies cereal and fold until evenly coated.

Allow the mixture to cool for 5 minutes, then divide and shape into ghost bodies.

Press chocolate eyes onto each ghost's face, securing with melted candy if necessary.

Let the ghosts sit at room temperature for about 60 minutes to set.
