One my mom used to make, I haven't made it very often. I also haven't tried it in a gluten-free form.
250 mL shortening, butter or margerine 250 mL brown sugar 90 mL corn syrup 2 eggs 10 mL baking soda 625 mL flour make the dough (by mixing everything together -- duh) roll it out quite thin on a floured surface cut circles (I use an inverted drinking glass) bake the circles at 175 C for 10-12 minutes. when the cookies have cooled, sandwich two together with your favourite jam in between. icing works inside as well.
