Preheat your oven to 350°F. While it heats, gather all ingredients and measure them out—this ensures nothing gets missed during mixing. Room temperature eggs are important here, so if yours are cold, let them sit on the counter for 10-15 minutes; they'll incorporate more evenly into the batter and create a better texture.

In a medium bowl, whisk together the flour, baking soda, cinnamon, salt, and nutmeg until evenly combined. This step distributes the leavening agent and spices throughout the flour, preventing lumps of baking soda and ensuring consistent flavor in every bite.

In a large mixing bowl, crack in the room temperature eggs and whisk them lightly. Add the cottage cheese, applesauce, and vanilla extract, whisking until fairly smooth—a few small lumps of cottage cheese are fine. Peel and mash the very ripe bananas directly into the mixture until mostly broken down but still slightly chunky; this adds texture and moisture. Finally, stir in both sugars until well combined. I like to mash the bananas by hand rather than with a mixer because it gives better control over the texture—you want some banana pieces, not a completely smooth purée.

Pour the dry ingredient mixture from Step 2 into the wet mixture from Step 3. Using a spatula or wooden spoon, fold and stir until just combined—stop as soon as no streaks of flour remain. Overmixing develops gluten, which makes the bread tough and dense, so resist the urge to beat it smooth.

Gently fold the chocolate chips into the batter using a spatula, distributing them evenly throughout. Pour the batter into a greased loaf pan (standard 9x5 inch size), smoothing the top with your spatula. I find it helpful to tap the pan gently on the counter a couple times to release any large air pockets—this helps the bread bake more evenly.

Place the loaf pan in your preheated 350°F oven and bake for 55-60 minutes, until a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter). The top should be golden brown. If the top is browning too quickly before the center is done, loosely tent it with foil for the last 15 minutes.

Remove the loaf from the oven and let it cool in the pan for about 10 minutes—this allows the structure to set without the bread becoming dry. Turn it out onto a wire rack to cool completely before slicing. This banana bread actually tastes better the next day after the flavors have had time to meld together.
