Preheat your oven to 350°F (175°C).
Grease your loaf pan with butter or line it with parchment paper.
Cream together the softened butter and sugar until light and fluffy.
Beat in the eggs one at a time, ensuring each is fully incorporated.
In a separate bowl, whisk together the all-purpose flour, salt, and baking soda.
Gradually add the dry mixture to the wet ingredients, alternating with the buttermilk.
Gently fold in the mashed bananas and chopped pecans using a spatula.
Transfer the batter to your prepared loaf pan and smooth the top.
Bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean.
Let it cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
