Preheat your oven to 350 degrees.
In a large bowl, add flour, baking soda, and salt, and whisk together. Set aside.
Add your eggs, granulated sugar, oil, sourdough starter, and vanilla extract to your stand mixer and mix until well combined.
Gradually mix the dry ingredients with the wet ingredients.
Next, mash up 2 – 3 bananas in a bowl and chop any inclusions you would like to add. I added walnuts, but you can add anything you prefer.
