Preheat your oven to 350°F. Grease a loaf pan and line it with parchment paper.

Blend the bananas, sugar, and oil together in a high-speed blender until smooth.

Add the flour and baking powder to the mixture and fold until combined.

Pour the batter into the prepared loaf pan.

Bake for 40-45 minutes, or until a skewer inserted in the center comes out mostly clean.

Allow the banana bread to cool completely in the pan before removing it. Once cool, slice and serve.
