Roll the dough out on a lightly floured board to a ½ to 3/4 inch thickness and cut out the oatcakes with a 3-4 inch biscuit cutter or an inverted drinking glass.
These will not brown a lot on top, so look for browning at the bottom edges to ensure they are fully baked but not overbaked. If using smaller biscuit cutters you will get about a dozen oatcakes. At this size they should bake for only about 15 minutes.
