Step 1

Preheat the oven to 350°.

Step 2

Lightly oil a 9-inch loaf pan and arrange a strip of parchment paper width-wise along the center, with just a bit hanging out over each side.

Step 3

Peel the bananas and place them into a large mixing bowl. Mash them well with a fork or potato masher.

Step 4

Add sugar, brown sugar, oil, and vanilla to the bowl. Stir until well-mixed.

Step 5

Add the flour to the bowl, then sprinkle the baking soda, cinnamon and salt on top of the flour.

Step 6

Stir everything together just until mixed. Don't overmix. The batter will be thick.

Step 7

Fold in the walnuts.

Step 8

Spoon the batter into the prepared loaf pan and smooth out the top with the back of a spoon.

Step 9

Sprinkle the top with brown sugar.

Step 10

Bake for 50 minutes, or until a toothpick inserted into the center comes out clean.

Step 11

Remove the pan from the oven and transfer it to a cooling rack. Allow the loaf to cool for at least 15 minutes before removing it from the pan.

Step 12

Slice and serve.
