Belgian Spice (Speculaas) Cookies

I don't make this often, but my great grandmother brought this to the United States when she emigrated from Belgium in the 1910's. I thought I should write it down somewhere I couldn't lose it. She made these like icebox cookies, but she said that in Belgium the bakers would have cookie molds of pretty shapes carved into wooden slabs. They would press the dough over the slabs, then turn the slabs upside down over a cookie sheet, give it a sharp tap and the cookies would fall onto the sheet ready for baking. (Note: I'm not at all sure how many this makes, my estimate was a total guess)
