Method

1. Preheat the oven to 200C/400F/Gas 4.

2. Mix the self-raising flour, oatmeal, wholemeal flour, caster sugar, baking powder and the salt in a bowl to combine.

3. Add the butter and rub into the flour mixture until it resembles breadcrumbs.

4. Fold in the walnuts.

5. Place the buttermilk and maple syrup into a separate bowl and mix well.

6. Add the buttermilk and maple syrup mixture to the dry mixture and mix well to make a dough.

7. Roll the dough out on a floured work surface to 3cm/1½in thick. Using a pastry cutter, cut out 12 scones (or as many as the dough will provide).

8. Place onto a greased baking tray and transfer to the oven to bake for 10-12 minutes, or until golden-brown.

9. Eat while still warm from the oven.
