Take a large bowl and add the ripe bananas. Use a fork to mash them well. They should be smooth with a few small lumps. This step helps create a soft texture in your banana bread.

Add melted butter to the mashed bananas. Then add sugar, brown sugar, eggs, and vanilla extract. Mix everything gently with a whisk. Make sure all ingredients are well combined and smooth.

Now add flour, baking soda, salt, and cinnamon. Mix slowly using a spatula. Do not overmix. Stop when you no longer see dry flour. This keeps the bread soft and fluffy.

Add chocolate chips to the batter. Fold them gently using a spatula. Make sure they are spread evenly. This gives chocolate flavor in every bite.

Grease your loaf pan with butter or oil. You can also use parchment paper. This prevents the bread from sticking and makes it easy to remove later.

Pour the batter into the prepared pan. Spread it evenly. Bake in a preheated oven at 180°C (350°F) for 50–55 minutes. The top should be golden and firm.

Insert a toothpick in the center. If it comes out clean, your bread is ready. Let it cool in the pan for 10 minutes. Then move it to a rack to cool fully.
