Preheat your oven to 350°F and position a rack in the center. While the oven heats, grease a 9x5 inch loaf pan (or similar size) with oil or cooking spray, making sure to coat the bottom and sides evenly. Grate your carrots on the fine side of a box grater to get about 3/4 cup of finely shredded carrots—this size matters because smaller shreds distribute better throughout the bread and cook evenly.

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ground ginger. Whisk for about 30 seconds to aerate the flour and distribute the leavening agents and spices evenly throughout—this ensures the bread rises uniformly and has balanced flavor in every slice. I always make sure to use freshly ground cinnamon when possible, as it makes a noticeable difference in the final flavor compared to pre-ground spices.

In a second bowl, combine the mashed banana, maple syrup, oil, milk, and vanilla extract, stirring until well blended. Once combined, add the grated carrots and light brown sugar to the wet mixture and fold together gently until the carrots are evenly distributed. The banana should be very ripe and soft enough to break apart easily with a spoon—avoid over-stirring at this point, as you want to keep the mixture slightly loose before combining with the dry ingredients.

Pour the wet ingredient mixture from Step 3 into the bowl with the dry mixture from Step 2. Using a spatula or wooden spoon, fold the ingredients together gently until just combined—stop as soon as you don't see streaks of dry flour, as overmixing develops gluten and results in a dense, tough crumb. Transfer the batter to your prepared loaf pan from Step 1, smoothing the top with a spatula so it bakes evenly. I like to give the pan a gentle tap on the counter a few times to release any large air pockets before it goes in the oven.

Bake for 45 minutes at 350°F, until a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter, but a few crumbs are fine). The top should be golden brown and a slight crack may form down the center—this is completely normal. If the top is browning too quickly before the cake is done, loosely tent it with foil for the last 10-15 minutes.

Remove the bread from the oven and let it cool in the pan for 10 minutes—this allows the structure to set. Turn the bread out onto a wire rack or cutting board and let it cool completely before slicing. This cooling time is important because the crumb continues to set as it cools, and slicing too early will result in a crumbly texture.
