*2 C all purpose flour
*¾ C sugar
*¾ t baking soda
*½ t salt
*3 large very ripe bananas, mashed well (1 ½ C)
*6 T (¾ stick) unsalted butter, melted and cooled
*2 large eggs
*¼ whole or low fat plain yogurt, or sour cream
*1 t vanilla
*½ C walnuts, toasted (optional)
1.Adjust an oven rack to the lower-middle position and heat the oven to 350 degrees. Grease an 8 ½ by 4 ½ inch loaf pan.
2.Whisk the flour, sugar, baking soda, and salt together in a large bowl. Mash the bananas in a Ziploc bag. In a medium bowl, whisk the mashed bananas, melted butter, eggs, yogurt and vanilla together. Gently fold the banana mixture into the flour mixture with a rubber spatula until just combined. Do not overmix! Fold in the walnuts (if using). The batter will look thick and chunky.
3.Scrape the batter into the prepared pan and smooth the top. Bake until golden brown and a toothpick inserted into the center comes out with just few crumbs attached, about 55 minutes, rotating the pan halfway through baking.
4.Let the loaf cool in the pan for 10 minutes, then turn out onto a wire rack and let cool for 1 hour before serving.
