Hi all!I am making some Royal icing Sugar Cookies for Halloween. I need a lot of black, and hate the taste. A very good suggestion is starting out with chocolate icing. However, I've never seen this for royal icing.My question is, if I add some cocoa powder to my royal icing recipe, will it still set the same? I need them to set hard like regular royal icing does.If not, do you have any other suggestions for good tasting (or tolerable) black royal icing?Thanks!!
