Ingredients
Method
- Heat the oven to 175°C (350°F). Line a 23 x 13 cm (9 x 5-inch) metal loaf pan with parchment. Whisk the flour, baking powder, baking soda and salt. In a separate bowl whisk the eggs, granulated sugar, oil and yogurt until smooth. Fold the dry mixture into the wet just until a few streaks remain, then fold in the apple.

- Mix the brown sugar and cinnamon. Spread half the batter in the pan, sprinkle the cinnamon mixture across the surface, then spoon the remaining batter over it. Draw a thin knife through the center once from end to end to make a loose ribbon.

- Bake for 50–60 minutes, until the top springs back and a skewer inserted away from an apple piece comes out without raw batter. Cool in the pan for 15 minutes, then lift onto a rack and cool for at least 50 minutes before slicing.
