Preheat your oven to 325°F (165°C) and grease a 9x5-inch loaf pan or line it with parchment paper.

In a medium mixing bowl, mash the overripe bananas until smooth. Add almond flour, eggs, baking powder, salt, and vanilla extract. Stir until well combined.

Pour the batter into the prepared loaf pan, smoothing the top with a spatula.

Bake in the preheated oven for 50 to 55 minutes, or until a toothpick inserted in the center comes out clean.

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