Preheat the oven to 350 F. Line a 9x5" loaf pan with parchment paper.
In a blender or food processor pulse the cottage cheese until it is smooth. In a bowl mash the ripe bananas, then add your smooth cottage cheese, sugar, vanilla, eggs and melted (cooled) butter. Combine.
In another bowl combine dry ingredients and then slowly combine into your wet ingredients until combined. If you wanted to add 1/4 cup mini chocolate chips and/or crushed nuts you could do so now.
Pour batter into lined loaf pan and bake for 50-60 minutes or until toothpick inserted into the center comes out mostly clean with moist crumbs attached. Allow to cool in pan for 5 minutes, lift out with sides of the paper and cool rest of the way on a cooling rack.
Notes
How to Add More Protein
You can use half cottage cheese listed with half high protein Greek yogurt to add more protein and/or add 1/2 scoop of protein powder into the dry ingredient bowl.
Best way to line a loaf pan with parchment paper
In order to get it to sit inside the pan and not want to pop out, crumple your piece up in a wad. Then undo the wad and press inside the pan, it will sit still better than if you leave it flat. This will make it easier to pour the batter in!
