Preheat your oven to 350°F (175°C). This step is crucial to ensure even baking.
Grease your loaf pan with a little oil or non-stick spray, or line it with parchment paper for easy removal later.
In a large mixing bowl, use a fork to mash the overripe bananas until smooth. You want them to be creamy with no large lumps.
Add the cottage cheese, unsweetened applesauce, sugar, and eggs to the mashed bananas. Whisk these ingredients together until well combined and smooth.
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Sifting is important for a light texture.
Gradually add the dry mixture to the wet ingredients. Using a spatula, fold the mixture gently until just combined. Do not overmix; a few lumps are okay.
Pour the batter into the prepared loaf pan and smooth the top with a spatula. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a cooling rack to cool completely. Slice and enjoy your Cottage Cheese Banana Bread warm or at room temperature!
