Hi friends, I am a fairly new baker and recently had a request to do memorial cookies for a sweet little boy from my community who left us too early. This little boy loved bubbles and I would really like to do something special with them for his mama. Has anyone ever done an iridescent royal icing cookie or have any tips on how to achieve the effect like in the photo? I can’t seem to find anything online and I’d be so appreciative for any help!
