Let me first just say that I do a lot of wet-on-wet cookies. BECAUSE I AM A NON-WAITER. I have no patience. I want instant gratification. I am sure these cookies would be just as cute if you did the chicks first and filled in a background later. Or if you did them on top of an already dry background. Hmmm....maybe I'll have to try those later....
Also, I use one consistency of icing. Its right down the line between outlining thick and flood icing thick. I go for a count of 12, if you know what I mean. But again...you can do these however you want to.
Immediately fill in the background color.
Done and done.
Wait -- I forgot to tell you about the cheeks. Pink luster dust on a dry cookie would be ideal. I don't have that. So I mix a tiny bit of pink food coloring with a bit of water. I dip a food paintbrush into it and dab it off on a paper towel. Then I lightly paint little pink cheeks. Easy peasy.
