Grease a one pound loaf pan with butter and line with parchment paper.
Measure all the cake ingredients into a bowl and beat for about 2 minutes until well blended. Pour the mixture into the prepared pan and level the top.
Bake in the oven for about 55 minutes until a toothpick inserted into the centre of the cake comes out clean. Leave the cake to cool in the pan for 5 minutes before lifting out and placing on a wire rack over a tray.
While your cake is baking, make the drizzle topping. Mix the cane sugar with the orange juice and stir to combine.
Use your toothpick to gently poke holes all over the surface of the cake. These will act as little channels for your topping to run into.
Pour the sugar and orange mixture all over the surface of the warm cake and leave to cool completely.
