Increase the oven temperature to 160°C fan-forced (320°F).
In a large mixing bowl, beat the eggs and sugar until pale and creamy.
Add the yoghurt, orange juice, oil, vanilla essence, baking powder and orange zest. Mix until smooth.
Scrunch the dried filo into small flakes with your hands and gradually fold it into the batter, mixing gently after each addition until evenly combined.
Lightly grease your baking dish with oil and dust it with flour to prevent sticking.
Pour in the batter, smooth the top and tap the dish gently to release any air bubbles.
Bake for around 40 minutes or until golden brown. Check with a toothpick. It should come out clean.
Once baked, remove from the oven and immediately pour over the cooled syrup.
Allow the cake to come to room temperature, then transfer it to the fridge for a few hours to chill before serving.
