Pre-heat oven to 170°C (340°F) on fan bake and line or lightly grease a loaf tin.

Sift all dry ingredients into a large bowl.

Blend wet ingredients in a blender until smooth, then pour into the dry. Lift and fold the mixture until almost combined, then add your walnuts and stir through – you want a few flour flecks to remain. Pour the mixture into your loaf tin and spread gently to the corners.

Bake at the bottom of your oven for 45-55 minutes until a skewer comes out dry in the middle – keep the loaf covered for the first half hour so it doesn't become too brown, then uncover the top for the last 15 minutes.

Remove, slice and serve warm, or let cool on a rack.
