285g/10oz plain flour
1 tsp bicarbonate of soda
½ tsp salt
110g/4oz butter, plus extra for greasing, or a butter alternative if dairy-free required

Sift the flour, bicarbonate of soda and salt into a large mixing bowl.
In a separate bowl, cream the butter and sugar together until light and fluffy.
Add the eggs, mashed bananas, buttermilk and vanilla extract to the butter and sugar mixture and mix well. Fold in the flour mixture.
