Preheat your oven to 350°F (175°C) and grease a 9x5 metal loaf pan.

Mash the bananas in a small mixing bowl until smooth and creamy.

Cream together the butter, granulated sugar, and brown sugar until light and fluffy.

Mix in the eggs, mashed bananas, and vanilla extract until well combined.

Sift together the flour, baking soda, baking powder, and salt in a separate bowl. Fold this mixture into the wet ingredients.

Gently fold in the chocolate chips until evenly distributed.

Pour the batter into the greased loaf pan and sprinkle additional chocolate chips on top.

Bake for 50-60 minutes, or until a toothpick inserted comes out clean.

Allow the bread to cool in the pan for at least 20 minutes before slicing.
