Step 1

Preheat oven to 350 degrees F. Use about 2 tablespoons of the olive oil to generously grease the bottom and sides of a loaf pan. It's OK if some pools at the bottom.

Step 2

In a large bowl, mix the remaining olive oil (just under 1/2 cup) with the brown sugar (1/2 cup).

Step 3

Add the eggs and mix for about 1 minute.

Step 4

Add the bananas (see notes) and mix together.

Step 5

Stir in the baking soda, kosher salt, cinnamon, and vanilla extract (1 teaspoon of each).

Step 6

Stir in the whole wheat flour (1/2 cup) and the all-purpose flour (1 cup) until just incorporated and no dry spots remain.

Step 7

Pour batter into prepared loaf pan and bake at 350 degrees for 50-60 minutes, or until toothpick inserted into center comes out clean.

Step 8

Allow to cool in pan for at least 10 minutes. It should pop right out if you flip the pan upside-down, but if you need to give it a boost you can run a knife along the sides before flipping it over.

Step 9

Cut the banana bread into 10 slices. I recommend serving it warm with salted butter spread on top.
