The recipe calls for mashed bananas. You can make it chunky or smooth. In any case, measure the flour and baking soda into a bowl. Add the mashed bananas and gently stir them together. Once the mixture is well-mixed, add the remaining ingredients: salt and baking soda. Mix well to combine. Place the loaf in the oven for about 1 and a half hours. If you'd like your loaf to be a little bit softer, add a few teaspoons of cinnamon to the batter.
