2 parts rolled oats (I used an empty 1kg yoghurt tub to measure mine, filling it once)
1 part unsweetened natural yoghurt (I used 500g)*
2 level tsp baking soda
Mix all ingredients in a bowl until well combined. Press into a non-stick loaf tin, or a loaf tin oiled and lined with baking paper. Bake at 180C for 40-45 mins, until a skewer comes out clean. Allow to cool completely before cutting as needed. Store in a sealed plastic bag.
*For a dairy-free alternative, use 2 tsp baking powder instead of soda, and almond or coconut milk instead of yoghurt. Baking soda requires yoghurt or cultured buttermilk to work.
*Yoghurt is the most expensive ingredient in this loaf - making your own will bring the cost down considerably.
