Preheat oven to 350°F (175°C) and grease a 9x5 inch loaf pan with non-stick spray or butter.
Place the cottage cheese, eggs, and melted coconut oil into a blender or food processor and blend until the mixture is completely smooth.
In a large mixing bowl, combine the mashed bananas with the blended cottage cheese mixture and vanilla extract.
In a separate medium bowl, whisk together the all-purpose flour, sugar, baking soda, salt, and ground cinnamon.
Gradually add the dry ingredients to the wet ingredients, folding gently with a spatula until just combined. Do not overmix.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake for 50 to 60 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
Remove from the oven and allow the bread to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
