Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper.
In a large mixing bowl, mash the ripe bananas until smooth. Add the melted butter, granulated sugar, and brown sugar, and stir to combine.
Beat in the eggs, one at a time, followed by the vanilla extract. Stir until the mixture is smooth.
In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
Gradually add the dry ingredients to the wet banana mixture, stirring just until combined. If using, fold in the sour cream for added moisture and richness. Gently mix in the walnuts or chocolate chips, if desired.
Pour the batter into the prepared loaf pan and smooth the top. Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the banana bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
