🌈 Rainbow scratch art t-shirt cookies 🌈 I iced these t-shirt cookies with flood consistency royal icing, let the icing dry overnight, and then covered them with a layer of black modeling chocolate (it's a little more difficult to work with than fondant because it's softer but it tastes amazing!). Revealing the rainbow designs underneath is the most fun part of making these cookies! The tutorial and recipes are in the Cookie Art Club. #sweetambscookies #rainbowartwork #rainbowcookies #royalicin
