Birthday puzzle cookies

I tried to make a birthday puzzle cookie for a friend. Also added a dozen of  small heart shaped cookies for fun and for munching.
That is my first attempt do to a puzzle cookie, which is not easy because the dough I was using spread a little. Not much but enough that the edges wont fit. So I had to cut them straight.
Since them I found a great recipe on LilaLoa blog that just great for this this kind of cookies, because the cookie does not increase at all.
