This sourdough apple cider donut bread is soft, moist, and coated in cinnamon sugar for all the cozy fall flavors of a classic apple cider donut.
Pour the batter into the prepared loaf pan and smooth the top. Bake for approximately 50–60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
If the top begins browning too quickly, loosely tent the loaf with aluminum foil for the remainder of the baking time.
