If using your oven, preheat it to 340 degrees F (170C) and spray your loaf pan with non-stick cooking spray, grease it with butter or line with baking parchment.
Add the oil or butter to a large mixing bowl. If using butter, place the bowl in the microwave and heat for 30 -60 seconds on high to melt the butter.
Add the bananas to the bowl with the oil or melted butter and mash with a fork. You can leave it a little lumpy.
Crack the egg into the bowl and mix into the mashed banana.
Then add the brown sugar, cinnamon and salt and mix well with a hand whisk (a fork will also work fine, but will just require a little more mixing).
Add the almond flour into the bowl as is, but sift the all-purpose flour or any other finer substitute flours (eg oat, buckwheat etc).
Simply place a sieve over the mixing bowl with the banana bread mixture, add the flours into the seive and press through with the back of a spoon.
Sift the baking soda through the seive too.
Remove the seive and, using a wooded spoon or spatula, gently fold the flours into the wet banana mixture until just combined.
Sprinkle in the chocolate chips and give the batter a light stir.
Do not overmix!
Pour the banana mixture into the prepared loaf pan and sprinkle some extra chocolate chips on the top.
Bake in the oven at 340 degrees F (170C) for 35 - 45 minutes. Alternatively, place in your airfryer at 300 degrees F (150C) for 25 - 35 minutes.
Since all ovens and airfryers differ, it's best to check on your banana bread around 35 minutes.
It's done when a skewer inserted into the loaf comes out clean or nearly clean. A little dampness on the skewer is fine and will result in a deliciously soft and moist chocolate chip banana bread.
If you prefer a very moist banana bread shave a few minutes off the baking time.
Allow the chocolate chip banana bread to cool in the pan for 15 minutes. Then remove the loaf and place on a wire rack to cool completely.
Slice the banana bread and enjoy!
