Preheat your oven to 350°F (175°C). This ensures that the banana bread bakes evenly and rises properly.

Grease a 9x5 inch loaf pan with butter or non-stick spray to prevent the bread from sticking.

In a large mixing bowl, mash the ripe bananas with a fork until smooth. Ripe bananas are sweeter and more flavorful, making them ideal for banana bread.

Add the melted butter to the mashed bananas and mix until well combined.

Stir in the beaten egg and vanilla extract until fully incorporated.

In a separate bowl, whisk together the baking soda, salt, and flour. This helps to evenly distribute the baking soda, ensuring the bread rises uniformly.

Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix, as this can lead to a dense bread.

If using, fold in the chopped nuts or chocolate chips at this stage.

Pour the batter into the prepared loaf pan, smoothing the top with a spatula.

Bake in the preheated oven for 60-65 minutes, or until a toothpick inserted into the center comes out clean. The baking time may vary based on your oven, so start checking at the 55-minute mark.

Once baked, remove the banana bread from the oven and let it cool in the pan for about 10 minutes.

Transfer the bread to a wire rack to cool completely before slicing. This helps prevent the bread from becoming soggy.

Slice and enjoy your delicious banana bread plain or with a spread of butter.
