Date Pinwheels

This recipe is woefully lacking in detail.  After you make and refrigerate the dough, take it out of the fridge, divide into two portions, roll each into a rectangle about a 1/4 inch thick and 8 x 12 inches, spread it with the date mixture, roll it long ways like a jelly roll, wrap in wax paper, chill it again, and then slice it into pinwheels (about a 1/4 inch thick) and then bake it.  Other similar recipes call for a 350° oven, so this seems a little hot.
