Preheat your oven to 350°F (175°C) to ensure even baking.
Grease your loaf pan with butter or non-stick spray; optionally line with parchment paper for easy removal.
In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, and ground cinnamon until well combined. Set aside.
In another bowl, mix Greek yogurt, honey, light brown sugar, melted butter, unsweetened applesauce, eggs, and vanilla extract until smooth and well blended.
Mash the ripe bananas with a fork until smooth but still slightly lumpy for texture.
Add the mashed bananas to the wet ingredients and stir gently to combine. Gradually fold in the dry ingredients until just mixed; avoid overmixing.
Pour the batter into the prepared loaf pan and smooth the top with a spatula. Bake for 55-65 minutes or until a toothpick inserted in the center comes out clean.
Remove the bread from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Slice and enjoy!
