Lay a piece of parchment paper (or use a pastry mat), and sprinkle it liberally with cocoa powder. Drop the dough on it and pat it down with your hands to about 1/2 thick. Cut with a biscuit cutter, and place on a nonstick cookie sheet. Bake about 12 - 15 min. (mine only take 12 min), in a preheated 425 degree oven.
