Prepare a Loaf Pan: Brush a 9-inch loaf pan with a tablespoon of avocado oil, then sprinkle with coconut sugar to prevent the batter from sticking.
Prepare the batter: In a medium sized bowl mix together the 1 ¼ cup almond flour, ¼ cup brown rice flour, 3 tablespoons tapioca starch, 3 tablespoons oat flour, 1 ½ teaspoons baking powder and ½ teaspoon sea salt. Set aside.
Place 3 tablespoons coconut milk, ¼ teaspoon orange zest and 1 tablespoon orange juice in a small bowl. Mix and set to the side.
Cream ½ cup almond butter and ½ cup banana in a KitchenAid mixer on medium high speed for 2 minutes, until very well mixed.
Add ¾ cup coconut sugar.
Add 3 eggs, one at a time, beating well between each addition. Next add 2 tablespoons of honey and 1 teaspoon vanilla extract. Fold the flour mixture into the batter gently.
Add in coconut milk, orange zest and orange juice.
Bake: Pour the batter into the pan, and sprinkle with 1 tablespoon sliced almonds.
Bake for 45 minutes, rotating halfway through, or until a toothpick inserted in the center comes out clean.
Let it cool in the pan for 10 minutes, then remove from the pan and cool on a rack.
