Preheat your oven to 350°F (175°C). Grease and lightly flour a 9x5 inch loaf pan, ensuring full coverage to prevent sticking.
In a large mixing bowl, whisk together the active sourdough starter, egg, milk, melted butter, and vanilla extract until they are thoroughly combined and smooth.
In a separate medium bowl, combine the all-purpose flour, granulated sugar, ground cinnamon, baking soda, and salt, whisking them well to distribute evenly.
Gradually add the dry ingredients into the wet ingredients, mixing gently with a spatula or wooden spoon until just combined. Be careful not to overmix the batter, as this can lead to a tough loaf.
Gently fold in the diced apples until they are evenly distributed throughout the batter.
Pour the prepared batter into your greased loaf pan, spreading it evenly with the back of a spoon or spatula.
For an optional sweet topping, drizzle 1 tablespoon of melted butter evenly over the batter, then sprinkle with 2 tablespoons of brown sugar.
Bake for 45-55 minutes, or until a wooden skewer or toothpick inserted into the center of the loaf comes out clean.
Allow the loaf to cool in the pan for about 10 minutes before carefully transferring it to a wire rack to cool completely.
Once fully cooled, slice and serve your delicious sourdough apple cinnamon loaf warm or at room temperature.
