Cookies with this baked-on frosting store well and can be stacked, and even frozen, once they have cooled. This works best with cutout cookies and best when it is piped on, as opposed to spread. This is also a great way to decorate delicate-textured cookies that could break by spreading frosting on. I found this recipe on the Land O' Lakes website, and I made up the variations myself. The yield depends on how you pipe the frosting and how big the cookies are, of course, so I just put that it makes enough frosting for 2 dozen cookies. Have fun!
