This makes a pretty and popular Christmas cookie. The filling came from a recipe in a newspaper at least 16 years ago, but to get the cookie I dreamed of, I tried the dough from many pinwheel cookie recipes before finally settling on this one about five years ago. Keep chilling the dough if it gets too soft while working with it.**A reviewer had trouble getting the pinwheel effect, so I have altered this recipe and ingredients to make the dough rectangle a little bigger. Also, I always bake my cookies on a Silpat so sticking is never an issue. I find I get more consistent browning and fewer overdone edges when using a Silpat, too.
