Preheat your oven to 350°F and grease a 9x5 inch loaf pan or 8x8 inch baking dish with oil or cooking spray. This ensures the oven reaches the proper temperature by the time your batter is ready, and a well-greased pan prevents sticking.

In a large mixing bowl, combine the brown sugar and room temperature eggs, then beat them together for about 1 minute until well combined and slightly lighter in color. Room temperature eggs blend more smoothly into the batter, creating a better texture. This initial mixing helps incorporate air into the batter, which contributes to a tender crumb.

Stir in the oil, cottage cheese, mashed banana, vanilla, and salt into the sugar and egg mixture from Step 2. Mix until just combined—the batter doesn't need to be perfectly smooth, especially with the cottage cheese, which naturally creates small curds that add wonderful texture and moisture to the finished bread.

In a separate bowl, whisk together the flour, baking powder, baking soda, and cinnamon. Pour the dry ingredients into the wet mixture from Step 3 and fold together gently with a spatula or wooden spoon until just combined—overmixing develops gluten and makes the bread tough. Once the dry ingredients are incorporated, fold in the chocolate chips. I always fold my chocolate chips in gently at the very end so they stay whole rather than getting mashed into the batter.

Pour the batter from Step 4 into the prepared pan, smoothing the top gently with a spatula. Bake at 350°F for 45-55 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs (the chocolate chips may leave streaks, which is fine). Start checking at 45 minutes to avoid overbaking.

Let the bread cool in the pan for 20 minutes—this allows it to set up enough to turn out cleanly without falling apart. After 20 minutes, run a thin knife around the edges and turn the bread out onto a wire rack to cool completely. I like to let mine cool all the way through before slicing so the texture stays moist and tender.
