Ingredients:
250g rolled oats
125g plain flour
220g brown sugar
225g butter
1/2 tsp baking soda
1/2 tsp water
Method:
Begin by dissolving the baking soda in the water. Then combine the oats, flour and brown sugar in a bowl. Add the butter and rub in or cut in with a knife until the mixture resembles coarse breadcrumbs. Add the baking soda mix (and more water if needed) and mix until the dough forms a ball.
Turn the dough onto a floured surface and roll out to about 7mm thick then use a 6cm pastry cutter to cut biscuits from the dough. Transfer these to a lightly-greased baking tray. Once all the dough is used up transfer to an oven pre-heated to 190°C and bake for about 12 minutes, our until golden brown.
Allow to cool on the tray for 20 minutes then transfer to a wire rack to cool completely.
