Firstly, mill the flour, I used half freshly milled soft white wheat and half spelt.
To your flour, add salt, baking soda, baking powder, and cinnamon, then mix to combine.
Next, smash up your bananas, if you like chunks of banana you can roughly chop them, if not mash to a banana puree.
Then to a mixing bowl add yogurt, eggs, butter, sugar (or honey), vanilla, and sourdough starer to the smashed bananas, and mix to combine.
Pour your wet ingredients into the dry ingredients, and stir just until combined, making sure not to overmix.
Gently Stir in your chocolate chips, nuts, or any mix-ins you desire. Let the batter it while the oven preheats, this will allow the fresh milled flour to start absorbing the liquid, an the bran to soften.
Preheat your oven to 350 degrees F
Line or grease a 5x9 bread loaf pan with parchment paper. (The smaller pans tend to spill some batter out.)
Bake for 60-70 minutes, just until a toothpick comes out clean. (*see notes for other pan baking times)
Let the banana bread loaf cool for 10 minutes, then remove to a wire rack to cool completely.
Lastly, Enjoy!
