I received a set of Valentine Cookie Cutters from a friend and was trying to think of other things that I could use them for. Then it occurred to me "tattoo cookies". I used the Sugar Cookie Recipe and Royal icing recipe from the Martha Stewart site. Both recipes worked out well. I recommend drawing out a picture before you start icing. Besides using the "flooding method" to decorate, I also used Foodwriter markers by Wilton.
I also made some cookies with white icing for my kids to decorate, which they loved. This was so easy that the two year old was able to do it. As you can see from the picture you don't have to add icing on the cookies to color them with the pens.
