Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan with shortening or line it with parchment paper.

In a medium bowl, mash the ripe bananas until smooth. Small lumps are okay for texture.

Add shortening, sugar, eggs, and vanilla extract to the mashed bananas. Beat until smooth and well combined.

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

Gradually fold dry ingredients into the banana mixture until just combined. Avoid overmixing to keep the bread tender.

Pour batter into prepared loaf pan and smooth the top. Bake 55–65 minutes, or until a toothpick inserted in the center comes out clean.

Allow bread to cool in the pan for 10–15 minutes, then transfer to a wire rack. Slice and serve warm or at room temperature.
