Preheat your oven to 350°F (175°C) and line a 9x5-inch loaf pan with parchment paper, leaving an overhang on the sides for easy removal.
In a medium bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg until evenly distributed. Make a small well in the center.
Peel and grate fresh ginger root until you have 2 tablespoons. Pro tip: Freeze your ginger for 10 minutes before grating for easier handling.
In a large bowl, whisk eggs until frothy, then add applesauce, melted coconut oil, coconut sugar, maple syrup, and vanilla extract. Blend until the mixture becomes a smooth, caramel-colored liquid.
Fold in the freshly grated ginger, ensuring it's evenly distributed through your wet ingredients.
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula. Limit yourself to no more than 12-15 strokes to avoid overmixing.
Gently fold in the diced apples and walnuts (if using) with just 4-5 broad strokes.
Pour the batter into your prepared loaf pan and smooth the top with a spatula. For an artisanal touch, arrange a few thin apple slices on top and sprinkle with a teaspoon of coconut sugar.
Bake for 55-60 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached. Shield the top with aluminum foil after 35 minutes if browning too quickly.
Allow the bread to cool in the pan for 15 minutes, then lift the bread out using the parchment paper overhang and transfer to a wire rack to cool completely.
