Preheat the oven to 350°F (180°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
In a large bowl, combine the mashed bananas and avocado. Add the eggs, honey or maple syrup, melted coconut oil, and vanilla extract. Mix well.

In a separate bowl, whisk together the whole wheat flour, baking soda, baking powder, salt, and cinnamon.
1 ½ cups whole wheat flour, 1 teaspoon baking soda, ½ teaspoon baking powder, ½ teaspoon salt, ½ teaspoon ground cinnamon
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.

Pour the batter into the prepared loaf pan and smooth the top.
Bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
Serve and enjoy!
