Preheat your oven to 350ºF and prepare a standard loaf pan with nonstick cooking spray or parchment paper.
In a large bowl, whisk together the flour, baking soda, cinnamon, and salt. Set aside.
Blend the cottage cheese in a high-speed food processor until smooth. Set aside.
In a stand mixer, cream together the brown sugar and butter on low to medium speed.
Add the eggs one at a time, mixing until combined.
In a separate bowl, mash the ripe bananas with a fork, then add them to the mixer along with the cottage cheese and vanilla. Mix until combined.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Pour in the milk and mix until incorporated. The batter may be slightly lumpy, which is okay.
Transfer the batter to the prepared loaf pan and bake for 30 minutes.
After 30 minutes, tent the loaf with foil to prevent over-browning, then bake for an additional 25 minutes.
Allow the banana bread to cool in the pan for 10 minutes before transferring it to a cooling rack.
Once cooled completely, slice and serve.
