Combine bananas, almond butter, eggs, and melted butter in a blender and mix well.
Add coconut flour, cinnamon, baking soda, baking powder, vanilla, and sea salt to the banana mixture in the blender; mix well.
Melt chocolate chips in the microwave oven for 1 minutes; stir. Microwave for an additional 15 seconds at a time until chips are completely melted.
Add 2 cups of the banana bread batter to the melted chocolate chips and stir well to combine.
In a parchment lined loaf pan, add a few blobs of chocolate mixture, then cover with some of the banana batter. Repeat, varying the areas where you spoon the chocolate batter.
Bake for 55-60 minutes, testing for doneness with a tootpick.
Let rest 10 minutes before lifting the bread out of the pan to cool completely on a rack. Let cool at least 2 hours before slicing.
Notes
If you do not have a blender, no worries! Mash the bananas well with a fork and mix them with the ingredients as stated in the recipe. You can use a regular mixer or do it by hand!
