Preheat Oven to 350˚F. Butter and flour a bread loaf pan (9.25"L x 5.25"W x 2.75"D).
In a mixing bowl using paddle attachment, cream together ½ cup softened butter and ⅔ cup sugar. Add 2 lightly beaten eggs.
Mash bananas with a fork until consistency of chunky applesauce and add them to the mixing bowl along with ½ tsp vanilla extract. Mix until blended.
Whisk together dry ingredients in a separate bowl: 1 ½ cups flour, 1 tsp baking soda and ½ tsp salt. Add to the mixing bowl and mix until incorporated.
Fold in ¾ cup chocolate chips then transfer to prepared bread pan. Sprinkle remaining ¼ cup chocolate over the top and bake at 350˚F for 55-65 minutes or until a toothpick inserted into the center comes out clean.
Let banana bread rest 10 min before transferring to a wire rack to cool.
