Preheat your oven to 350F and prep a loaf pan (9x5) with parchment paper.
Mash your bananas in a small bowl and set aside.
In a large bowl, cream together softened butter and both sugars using a hand or stand mixer for 2-3 minutes until the mixture is light and fluffy.
Add in your remaining wet ingredients - eggs, vanilla and bananas that were set aside. Mix until combined.
Add in your dry ingredients - flour, baking soda, baking powder, & salt. Use a spatula to mix until just combined. Fold in half of your chocolate chips.
Pour batter in to your prepared pan, and sprinkle with your remaining chocolate chips.
Bake for 50-60 minutes, or until golden brown. When finished, let the loaf cool for 10 minutes in the pan before removing to cool for another 10 minutes on a cooling rack
