My friend requested birthday cookies, so I decided to make a variety of colorful spring flowers and butterflies! I used royal icing for both. For the flowers, I piped the outline of each cookie and the outline of each center using stiff consistency icing. I made sure that the outlines were dry before flooding each cookie with thinned out brightly colored royal icing. For the butterflies, to do the cool swirly marble effect, make thinned out royal icing and use a toothpick to swirl different pops of color with food gel, then dip the cookies! Couldnt be easier and looks awesome!
