Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
In a mixing bowl, mash the ripe bananas with a fork. Add the Chobani yogurt, melted butter, sugar, eggs, and vanilla extract. Whisk until smooth.
In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
If using, fold in the chopped walnuts gently with a spatula.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake in the preheated oven for 60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the banana bread to cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Slice and serve.
