Preheat the oven. Preheat your oven to 350°F and grease a loaf pan with cooking spray or line it with parchment paper.
Combine wet ingredients. In a large mixing bowl, combine the mashed bananas, eggs, maple syrup, melted coconut oil, and vanilla extract. Mix until well combined.
Mix together dry ingredients. In a separate bowl, whisk together the almond flour, baking powder, and salt.
Combine wet and dry. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
Fill a loaf pan. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake until done. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Cool, slice, and enjoy! Allow the banana bread to cool in the pan for 10-15 minutes, then transfer it to a wire rack to cool completely before slicing.
