In a mixing bowl, and with a hand mixer, mix together the coconut oil, honey, eggs, bananas and sour cream until smooth. Add the rest of the ingredients and mix just until combined. Spray two bread loaf pan heavily with cooking spray. Place a piece of parchment paper the size of the bread pan into the bottom and sides of the pan (so the bread will remove more easily after baking). If you don't have parchment paper, just lightly flour the pan.
Pour the batter into the bread loaf pans. Bake at 350 for 40-50 minutes, or until the center of the banana bread is cooked through and no longer doughy. Slice bread once it's been removed from the pan and cooled.
