Preheat the oven to 350 degrees and grease a standard loaf pan.
In a small bowl, combine the flour, baking soda, baking powder, salt, cinnamon, and ginger.
In a large bowl, mix together the egg, coconut oil, maple syrup, and applesauce. Add the dry ingredients and stir to combine. Transfer the batter to the prepared loaf pan.
Bake for 50 to 60 minutes, or until a toothpick inserted in the center of the loaf comes out clean. Keep an eye on it starting at 50 minutes, because it’ll be dry if you let it bake for too long.
Cool on a wire rack in the pan for 10 minutes, then remove the loaf from the pan and cool completely. Store in an airtight container at room temperature for up to 3 days, or freeze for later.
