Start by preheating your oven to 325°F and greasing a 9x5 inch loaf pan with butter or cooking spray. While the oven heats, measure out all your ingredients and set them on your counter—this ensures nothing is forgotten and cooking flows smoothly. Make sure your eggs and butter are at room temperature, as they incorporate better into the batter and create a more tender crumb.

In a medium bowl, whisk together the flour, baking soda, salt, and ground cinnamon. Whisking aerates the dry ingredients and distributes the leavening agents evenly throughout, which ensures even rising. Set this bowl aside—you'll fold it into the wet ingredients at the end to keep the batter light and tender.

In a large bowl, combine the melted and cooled butter with both sugars, stirring until well combined. The sugar dissolves slightly into the butter, creating a smooth base that will help distribute moisture throughout the bread. This step takes just a minute but is crucial for even texture.

Add the mashed bananas, room-temperature eggs, Greek yogurt, and vanilla to the butter-sugar mixture from Step 3. Stir until everything is well combined and relatively smooth. The yogurt adds moisture and tang that keeps the bread tender and prevents it from drying out—I find it makes all the difference in texture compared to using milk or extra eggs alone.

Add the dry ingredient mixture from Step 2 to the wet ingredients from Step 4, folding gently with a spatula until just combined—do not overmix, as this develops gluten and makes the bread tough. Once the dry ingredients are mostly incorporated, fold in the chocolate chips gently. I prefer Ghirardelli semi-sweet chips because they melt beautifully and add rich flavor without being overwhelming.

Pour the batter into your prepared loaf pan and smooth the top slightly. Bake at 325°F for 1 hour to 1 hour 15 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs. The lower temperature (compared to standard 350°F banana bread) allows the bread to cook gently and prevents the outside from browning too quickly before the inside is done.

Remove the bread from the oven and let it cool in the pan for about 10-15 minutes. This brief rest allows the structure to set so it doesn't fall apart when you turn it out. Then turn the bread out onto a wire rack to cool completely before slicing. This cooling period is essential—slicing too early will cause crumbling and an uneven texture.
