Preheat oven to 350 and grease a 8×4 inch loaf pan with butter or cooking spray.
Combine flour, salt and baking soda in a large mixing bowl, stirring gently with a whisk.
Combine sugar, butter, eggs, bananas and yogurt in another bowl, and stir vigorously until well combined.
Pour banana mixture into flour mixture and stir until no flour streaks remain. Scrape batter into loaf pan and bake for one hour or until a toothpick inserted in the center comes out clean.
Cool in the pan for about 15 minutes, and then remove from the pan and continue cooling on a rack. Make sure to eat a piece while it is still warm, and make sure you try a piece toasted before it’s all gone!
