Preheat oven to 175°C. Grease a 23 x 13 cm loaf pan with butter or line with parchment paper for easy removal.
02 -
In a large mixing bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt until evenly blended.
03 -
In a separate bowl, vigorously whisk buttermilk, melted butter, eggs, and vanilla extract until smooth and fully combined.
04 -
Gently stir the wet mixture into the dry ingredients using a spatula until just incorporated. Avoid overmixing to maintain a tender crumb.
05 -
In a small bowl, mix brown sugar with ground cinnamon until thoroughly combined.
06 -
Spread half of the batter evenly in the prepared loaf pan. Sprinkle with half the cinnamon-sugar mixture. Top with remaining batter, then scatter over the rest of the cinnamon-sugar swirl. Use a knife to gently swirl for a marbled effect.
07 -
Bake in the centre of the preheated oven for 50–60 minutes, or until a toothpick inserted into the centre emerges clean with a few moist crumbs.
08 -
Let the bread cool in the pan for 10 minutes before transferring to a wire rack to cool further. This ensures structural integrity for clean slicing.
09 -
While the loaf remains warm, brush the top with melted butter. Combine granulated sugar and cinnamon, then sprinkle evenly over the buttered surface.

Once the topping is set, slice thickly and serve as desired.
