Preheat the oven to 350°F (175°C) and prepare a 9x5-inch loaf pan by greasing it or lining it with parchment paper.

Mash the ripe bananas in a large mixing bowl until smooth but still slightly chunky, about 2-3 minutes.

Add the eggs, honey or maple syrup, and salt to the mashed bananas; mix together until fully combined, about 1-2 minutes.

In a separate bowl, combine almond flour, baking soda, and optional cinnamon; stir until well mixed, about 1 minute.

Gently fold the dry ingredients into the wet ingredients until just combined, about 30 seconds to 1 minute.

Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Bake for 45-55 minutes until golden brown.

Remove from oven and let cool for 10-15 minutes before transferring to a wire rack to cool completely before slicing.
