Preheat your oven to 350°F (175°C).
Cream together the softened butter and sugar until light and fluffy, about 3-4 minutes.
Add the eggs, one at a time, mixing well after each addition.
In a separate bowl, whisk together the all-purpose flour, salt, and baking soda.
Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk.
Fold in the mashed ripe bananas and chopped pecans using a rubber spatula.
Pour the batter into your greased loaf pan and smooth the top. Bake for 60-70 minutes.
Allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack.
