Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper.
In a large mixing bowl, mash the ripe bananas with a fork until smooth.
Add the eggs, honey, and vanilla extract to the mashed bananas and whisk until well combined.
In a separate bowl, whisk together the almond flour, baking soda, salt, and ground cinnamon.
Pour the dry ingredients into the wet ingredients and stir until just combined.
Add the melted unsalted butter to the batter and mix gently until incorporated.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean.
Remove the banana bread from the oven and allow it to cool in the pan for 15 minutes.
Transfer the bread to a wire rack to cool completely before slicing and serving.
