Ingredients
Method
Preparation
- Preheat the oven to 180°C (350°F). Grease an 8" x 4" loaf pan thoroughly and line with parchment for easy removal.
- In a small bowl, toss diced apples with 15 g granulated sugar and 10 g cinnamon until evenly coated.
- In another bowl, mix 50 g brown sugar with 10 g cinnamon for the topping or swirl.
Making the Batter
- In a medium bowl, whisk the egg, 65 g granulated sugar, and 5 g vanilla until slightly pale.
- Stir in 55 g vegetable oil and 100 g sourdough starter until combined.
- In a separate bowl, sift (or whisk) 150 g all-purpose flour with 10 g baking powder and 3 g salt.
- Gently fold the dry ingredients into the wet mixture until just combined. Do not overmix.
- Fold in the apple mixture, reserving a few pieces for the top.
Baking
- Pour half the batter into the prepared pan, sprinkle the cinnamon-brown sugar mixture across the center, then add the remaining batter.
- Smooth the top and press reserved apple pieces lightly into the surface.
- Bake at 180°C (350°F) for 45–55 minutes, checking at 40 minutes.
- If the top darkens too quickly, tent loosely with foil for the last 10–15 minutes.
- Cool in the pan for 10–15 minutes, then transfer to a rack.
Glazing
- When mostly cooled, whisk 150 g powdered sugar with 40 g milk and drizzle over the loaf.
