Preheat your oven to 350˚F. Start by buttering and flouring a loaf pan that measures 9.25 inches long by 5.25 inches wide and 2.75 inches deep. This ensures that your bread won’t stick, allowing for an easy release once baked.
In a large mixing bowl, cream together 1/2 cup of softened butter and 2/3 cup of sugar using a paddle attachment. Mix until the mixture is light and fluffy, which should take about 2 to 3 minutes. This step is crucial as it incorporates air into the batter, giving the bread a lovely texture.
Add 2 large eggs to the mixing bowl, lightly beaten. Mix until fully combined, scraping down the sides of the bowl to ensure everything is properly incorporated.
Mash 3 medium ripe bananas with a fork until they reach a chunky applesauce consistency. Add the mashed bananas and 1/2 tsp of vanilla extract to the mixing bowl. Stir until blended, creating a beautifully fragrant batter.
In a separate bowl, whisk together 1 1/2 cups of all-purpose flour, 1 tsp of baking soda, and 1/2 tsp of salt. This dry mix is essential for the structural integrity of your bread, providing the necessary foundation.
Gradually add the dry ingredient mix to the wet ingredients, stirring just until incorporated. Be careful not to overmix; you want the flour to just disappear into the batter, which will help keep it tender.
Gently fold in 3/4 cup of semisweet chocolate chips, ensuring they are evenly distributed throughout the batter. Reserve the remaining 1/4 cup of chocolate chips to sprinkle on top before baking.
Transfer the batter into the prepared loaf pan, smoothing it out with a spatula. Sprinkle the reserved 1/4 cup of chocolate chips on top, giving your bread an appealing finish and an extra burst of chocolate flavor.
Bake in the preheated oven for about 55 to 65 minutes. Keep an eye on your bread; you want it to be golden brown on the edges and a toothpick inserted in the center should come out clean.
Once done, allow the banana bread to rest in the pan for about 10 minutes. Carefully transfer it to a wire rack to cool completely. This will help maintain its texture!
