Step 1

Preheat the oven to 190C/170C fan/Gas 5.Lightly grease two baking trays.

Step 2

Take a large mixing bowl and add all the dry ingredients. Mix together.

Step 3

Dice or grate the butter then rub it into the dry ingredients until you have a mixture that looks like breadcrumbs.

Step 4

Stir in enough of the beaten egg to make a soft dough, using your hands to bring the mixture together.

Step 5

Generously sprinkle the work surface with oatmeal. Put the dough on the oatmeal, sprinkle more over the top then roll out 3-5 mm thick.

Step 6

Using a round, 8cm cutter, cut out biscuits and transfer them to the greased baking trays. Gather up the scraps, re-roll and cut out more biscuits until all the dough is used up, dusting with more oatmeal as needed.Depending how thick you rolled the dough, you should get 12-15 biscuits.

Step 7

Prick holes into each biscuit in a pleasing pattern using a skewer or cocktail stick.

Step 8

Put the trays of biscuits in the preheated oven until cooked through and golden brown (15-20 min). Turn the trays around half way through if the biscuits are cooking unevenly.Transfer biscuits to a wire rack until completely cold before storing in an airtight container.
