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

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

In a large mixing bowl, mash the ripe bananas with a fork until smooth. Ripe bananas are sweeter and provide moisture.

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

Stir in the egg and vanilla extract until well incorporated.

In a separate bowl, whisk together the flour, baking soda, salt, granulated sugar, and brown sugar until evenly mixed.

Pour the dry ingredients into the wet ingredients. Stir gently with a spatula until just combined. Do not overmix; a few lumps are okay.

Fold in the chocolate chips, ensuring they are evenly distributed.

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

Bake in the preheated oven for 55-65 minutes, or until a toothpick inserted into the center comes out clean.

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 maintain its moisture.
