Gently press on the top of the biscuits with the back of a fork to slightly flatten before placing into your pre-heated oven and baking for 12 - 15 minutes or until they begin to turn golden.
Carefully remove from the oven and allow the biscuits to cool on the baking tray for 10 minutes before transferring to a wire rack to cool completely.
