Please 2 ½ oranges. Slice them in about 1cm thick slices. Now cut open the vanilla pod and scrape out it's essence.

In a bowl add the eggs, sugar, butter, buttermilk, vanilla essence, orange flavoring and a pinch of salt, and mix in to a smooth paste. Now mix the flour and baking powder and sieve onto the egg mixture, and mix in well.

Now pour the mixture onto a greased baking tray (about 30 cm x 40 cm in size), and place the orange slices on top. Place the tray into the preheated oven (about 180 degrees Celsius) and bake for about 20-30 minutes.

Juice the leftover half orange, and once the cake comes out of the oven just drizzle it with a teaspoon over the hot cake.

After allowing the cake to cool, cut into slices and sprinkle with icing sugar before serving.
