Preheat your oven to 375° F.
Add the flour, baking soda, and salt to a medium-sized mixing bowl and whisk well to incorporate ingredients.
In a separate, large mixing bowl, add the softened butter and sugars. Using an elecric mixer, beat on medium speed to cream. The mixture will become fluffy and slightly changed in color.
Switch the mixer speed to low and beat in the banana and vanilla.
Using a wooden spoon or silicon spatula, stir in the mixture of dry ingredients. Once dough appears evenly mixed, stir in the chocolate chips.
*Drop by rounded tablespoon (I use a .667 fl. oz. portion scoop) onto parchment-lined baking sheets. Bake for 10 - 12 minutes.
