Baking banana bread is as much about the process as it is about the final product. Here’s a step-by-step guide to help you create your own slice of heaven:

1. Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and set it aside.
2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
3. In a large bowl, beat the melted butter and sugar together until smooth and creamy.
4. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
5. Mix in the mashed bananas and sour cream until fully combined.
6. Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Be careful not to overmix!
7. If using, fold in the chopped nuts gently.
8. Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
9. Bake in the preheated oven for 60-65 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
10. Allow the bread to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.

Remember, patience is key! Letting the banana bread cool completely ensures it slices beautifully and maintains its moist texture.
