Preheat oven to 350°F (175°C). Spray a loaf pan with non-stick spray.

In a large bowl, mash the ripe bananas until smooth.

Stir in the Greek yogurt, applesauce, vanilla extract, and eggs until fully combined.

In a separate bowl, whisk together the flour, sweetener, baking soda, cinnamon, and salt.

Gradually add the dry ingredients to the wet mixture. Stir just until combined, being careful not to overmix.

Pour the batter into the prepared loaf pan. Bake for 45–55 minutes, or until a toothpick comes out clean.

Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
