Preheat the oven to 350 degrees. In a large bowl, mix the almond flour, baking soda, and salt.

Pulse the avocado and bananas in a food processor until creamy. Add the coconut oil, vanilla, honey, and egg, and pulse to combine.

Using a rubber spatula gently mix the wet ingredients into the dry ingredients and mix to form a batter, then fold in the macadamia nuts.

Line an 8½ x 4½-inch medium loaf pan with parchment paper and spread the batter across the pan.

Bake until a toothpick inserted into the center comes out clean, about 45 to 50 minutes.
