How to make
Beat the eggs with the sugar until fluffy. Gradually add the oil and melted butter, cinnamon, vanilla, and baking powder. Optionally, you can add rum essence. Add the apples lastly.
You're going to end up with a very thick mixture. Pour the dough into an oven dish that's been greased and sprinkled with a little flour. Bake in preheated 360°F (180 °C) oven. Finally, sprinkle with powdered sugar.
