Step 1

Preheat your oven to 320ºF (160ºC). Line a 2-pound loaf tin with baking parchment.

Step 2

In a large bowl, whisk together the granulated sugar, light brown sugar, eggs, vegetable oil, and sour cream. Add the melted and cooled butter, and mix until well combined.

Step 3

In a separate bowl, mash the ripe bananas until smooth. Stir the mashed bananas into the wet mixture.

Step 4

In another bowl, whisk together the flour, baking soda, salt, and 1 cup of chocolate chips.

Step 5

Add the dry ingredients to the wet mixture and mix until just combined.

Step 6

Pour the batter into the prepared loaf tin. Sprinkle the reserved 2 tablespoons of chocolate chips on top.

Step 7

Bake in the preheated oven for 35-45 minutes, or until a skewer or toothpick inserted into the center comes out with just a few moist crumbs.

Step 8

Allow the bread to cool in the tin for about 10 minutes, then transfer to a wire rack to cool completely before slicing.
