Preheat your oven to 350°F (175°C). Prepare a 9x5 inch loaf pan with nonstick spray and parchment paper.

Mash the three overripe bananas until smooth with a fork or potato masher.

Stir in one cup of granulated sugar into the mashed bananas, then add two eggs, vanilla extract, and canola oil. Mix until smooth.

In a separate bowl, sift together one and one-third cups of flour, baking soda, and salt. Gradually fold this into the banana mixture until just combined.

Pour the batter into the prepared loaf pan and bake for 45-50 minutes, checking with a toothpick for doneness.

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