Preheat the oven to 350 degrees F and line an 8.5X4.5 loaf pan with parchment paper.
Add the mashed bananas, almond butter, eggs, and vanilla to a large mixing bowl and mix well.
Add in the remaining ingredients minus the chocolate chips, mixing until no clumps remain.
Fold in the chocolate chips and pour the batter into the parchment-lined loaf pan.
Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. Cool and then slice and enjoy with a slab of your favorite nut butter!
Store leftovers covered in the fridge.
