Step 1

Preheat oven to 180°C. Grease a 10cm x 24cm (base measurement) loaf pan and line the base and 2 long sides with baking paper, allowing the sides to overhang. Combine the flour, baking powder and sugar in a large bowl.

Step 2

Whisk the egg, oil, buttermilk and mashed banana in a large jug. Add to the flour mixture and stir to combine. Spoon into the prepared pan and smooth the surface.

Step 3

Melt butter in a large frying pan over high heat. Sprinkle the cut side of sliced banana with the extra sugar. Cook for 1-2 mins each side or until caramelised.

Step 4

Arrange sliced banana over the banana bread batter in the pan. Bake for 45 mins or until a skewer inserted in centre comes out clean. Set aside in the pan for 10 mins to cool slightly before transferring to a wire rack. Cut into slices and serve warm or at room temperature.
