Step 1

Preheat the oven to 200°C. Combine flours in a large bowl. Add bicarb, baking powder and 1 tsp salt and stir to combine. Make a well in the centre. Pour in the buttermilk, then using your hands bring the mixture together into a soft sticky dough.

Step 2

Turn dough out onto a floured surface. Knead lightly and form into a round. Place on a baking tray sprinkled with flour. Using a sharp knife, make two slashes in the top of dough to form a cross. Brush dough with extra buttermilk and scatter with oats.

Step 3

Bake for 1 hour or until golden and base sounds hollow when gently tapped.
