Preheat your oven to 350°F (175°C) and prepare a loaf pan by greasing it lightly or lining it with parchment paper.

In a large mixing bowl, mash the ripe bananas until slightly chunky, aiming for about 1 ½ to 2 cups of mashed bananas.

Add the eggs, unsweetened applesauce, and vanilla extract into the bowl with the mashed bananas and whisk until smooth.

In a separate bowl, whisk together the whole wheat flour, baking powder, and cinnamon until evenly mixed.

Gently fold the dry ingredients into the wet mixture using a spatula until no dry flour remains.

Transfer the batter into the prepared loaf pan and smooth the top. Bake for 50-60 minutes.

Allow the banana bread to cool in the pan for 10-15 minutes, then transfer to a wire rack to cool completely.
