Core the apples and slice horizontally.

Whisk egg + sugar + condensed milk. Add water. Whisk until well combined.

Add self-rising flour bit by bit. Add cinnamon powder. Add oil and whisk several times. Put the apple slices inside the mixture. Wait for about five minutes until the mixture is a bit bubbly.

Heat a nonstick pan. I use low heat. Carefully put a slice of apple coated in batter to the pan. After bubbles form, flip it.

You'll have some leftover batter. You can make regular pancakes with it.
