1

Mix the whole wheat flour, bicarbonate of soda and salt in a large bowl. Add the walnuts.

2

Cream the butter and the brown sugar until fluffy in a separate bowl.

3

To this butter-sugar mixture, add the eggs, mashed bananas, buttermilk, vanilla extract and mix well.

4

Fold everything into the flour prepared in the Step 1.

5

Grease a 20cm x 12.5 cm loaf tin (or a cake tin) and coat it thoroughly with the rolled oats.

6

Pour the flour mixture into this tin.

7

Preheat the oven to 180°C and bake the bread for about an hour or until it turns golden brown and the toothpick comes out clean when inserted.

8

Allow it to cool for about 10-15 minutes and serve warm or cold, though I personally prefer a warm one.
