Preheat your oven to 350 degrees F.
In a large mixing bowl, whisk together the mashed bananas, almond butter, avocado oil, eggs, maple syrup and vanilla extract.
Next, add in the flour, cinnamon and baking soda. Use a rubber spatula to combine the ingredients. If you are using chocolate chips or other mix in's, fold them into the batter. Don't overmix the batter. Mix until just combined. You can wind up with tough or gummy banana bread that won't rise if you keep mixing.
Grease an 8x4 loaf pan or use parchment paper. Add the banana bread batter into the loaf pan.
Bake at 350 degrees F for 40 minutes, or until a toothpick inserted comes out clean.
Let the bread cool in the pan for 5 minutes. Then, gently remove it from the pan and place it on a wire cooling rack.
Allow the banana bread to cool for at least 1 hour before slicing.
