Garabatos - Scribble Cookies

As Fany Gerson mentions in the headnotes to this recipe, these are not necessarily traditional Mexican baking - they're simple butter cookies with chocolate filling and chocolate icing drizzled (or scribbled) over the top. They certainly tasted just fine; they're a nice cookie indeed, but they didn't stand out as being unusual or remarkable, which I suppose, given the nature of this intriguing book, I expected.

Update: they did improve on re-eating, and my kids really liked helping make them (drizzling chocolate sauce on top) and eating them.
