Prepare your cake pan by coating it with oil. If you don't have spray fat, you can brush the oil on. Make sure the pan is well-coated without any pooling. Coat the pan with flour, ensuring every nook and cranny is covered. Tap out the excess flour. You can save the leftover flour for other uses.

In a bowl, combine 150g of flour, 170g brown sugar, 1 tsp baking soda, 1 tsp cloves, 1 tsp cinnamon, and the zest of 2 oranges. Mix them together and set aside.

In another bowl, mix 150g milk and 1 egg together.

Add the milk and egg mixture to the bowl of dry ingredients. Stir until you have a smooth batter with no lumps of sugar or flour.

Pour in 115g of melted butter and mix it in thoroughly. Make sure there are no streaks or lumps in the batter.

Pour the batter into the prepared loaf pan and spread it evenly.

Bake at 200°C/400°F for 35 minutes or until a toothpick comes out clean when inserted into the cake.
