Marian's banana walnut bread

Anyone who has worked at the Oban Times newspaper on the west of Scotland in recent times (as my other half did) will have sampled Marian Miller's delicious banana loaf - so it's well worth bringing to a wider audience.

Ingredients

125g butter
1 tsp vanilla essence
3/4 cup caster sugar
2 eggs
1 cup mashed bananas (three soft bananas)
3/4 cup self raising flour
3/4 cup plain flour
1/2 tsp bicarbonate of soda
1/2 cup walnuts (or sultanas if preferred)
1 loaf tin

Method

Cream the butter, sugar and essence with an electric mixer until light and fluffy.
Add the eggs one at a time.
Sift the dry ingredients together and then add half the dry ingredients, bananas and walnuts to the creamed mix and fold in.
Then add the other half and fold in.
Bake at 180C for 55-65mins.
