Add the flour and baking powder and bring together. You should have a stiff dough.
Turn the mixture onto a lightly-floured work surface and roll out to about 6mm thickness.
Cut into ka'ak shapes (typically crescents), transfer to a lightly-greased baking tray.
Bake for 12-15 minutes, or until a light golden brown. Remove from the oven, sprinkle a little caster sugar over the top then transfer to a wire rack to cool completely.
