Pour baking chips into a medium-sized microwave-safe glass bowl. Melt chips at 50% power in 30 second increments, stirring well each time until baking chips become smooth.
Place a handful of wafers into melted mixture and stir until coated. Place cookies onto parchment lined baking sheet 1 inch apart from each other. Sprinkle with crushed peppermint if desired. Repeat with remaining wafers.
Allow cookies to harden, approximately 30 minutes.
