Preheat oven to 350℉/180℃.

Place apple slices in a large bowl. In a separate deep bowl, beat 3 eggs with pinch of salt and sugar to a light yellow and airy hue, add flour and baking powder sifted through a sieve, mix to a uniform batter, add melted butter, mix well, add orange or lemon zest (optional) and cinnamon, add milk and vanilla extract and mix until there is a uniform batter.

Pour the batter over the cut apples, mix to a uniform mixture. Leave some apple slices aside to cover the top of the cake.

Grease a 13”x5” loaf pan with melted butter. Pour mixture into the mold. Arrange remaining apples over the batter as shown in the video.

Bake for 30 minutes at 350℉/180℃, lower the temperature to 300℉/150℃ and bake for another 30 minutes or until the cake is shaped and the apples have a golden-brown hue.

Remove from oven to cool, remove from pan and place on a cake plate, sprinkle with powdered sugar and serve warm or cold.
