Separate your Peeps cats, then give the white exposed sides a quick mist of the edible spray paint. Set aside.
Place a piece of parchment on a large cutting board or baking sheet.
Melt the bag of purple candies in a glass measuring cup or small bowl. Use the defrost setting on your microwave to slow the process and avoid overheating the candy melts. Stir every 20 seconds until there are only small pieces left. Then take the container out and stir until those last bits dissolve. Spread the candy out on parchment. 1/8 to 1/4 inch thick.
Melt the black candy as well, Due to smaller volume this will go much faster. Use rubber/silicone spatula to scrape melted candy into a plastic sandwich snip off a corner and make a line swaying back and forth over the purple candy surface.
Apply the Peeps cats, then moons and finally stars. Set aside to cool or place in refrigerator to harden faster. Once firm, crack into serving size pieces.
