Raisin spice bar recipe?

Hey all! I wonder if anyone has a recipe for a spice bar-type cookie including molasses, raisins, ginger, cloves, cinnamon and covered with a thin, sort of crackly powdered sugar glaze? I've been scouring the interwebs with not much luck. My mom used to buy such a bar at a little card shop near my childhood home in AZ, and it's long since closed. I haven't had them in ages, but I seem to recall that maybe the recipe was of Amish origin? It was a very dark, spicy yet soft bar cookie.
Thanks in advance!
