In a large bowl, combine the unbleached and whole wheat pastry flours, baking soda, baking powder, salt, ginger, cinnamon, nutmeg and cloves. Whisk to mix well, reserve. In a stand mixer or a large bowl with an electric beater, cream the butter until soft. Add the brown sugar and beat, scraping and mixing until well-mixed. Add the molasses and beat, scrape down and add the egg, beat again until thoroughly combined. On low speed, stir in the flour mixture. Divide the dough into four pieces. Form a rectangle of each and place between sheets of parchment and roll out to 1/4-inch thickness. Stack the dough rectangles, separated by parchment paper, on a baking pan and wrap tightly, chill for three hours, or up to 24 hours.
