Peel the KIKU apples and cut into thin slices. Combine the flour, the milk, the eggs, and a pinch of salt in a mixing bowl.
Heat the butter in a skillet and brown the sliced apples. Carefully pour approx. 1 cm (0.5 inch) of batter into the skillet (no less). Cook on one side, then flip and cook on the other—like when cooking regular pancakes.
Once fully cooked, use two forks to shred the pancake into smaller pieces. Sprinkle with sugar and wait until caramelized. Add to a plate, dust with powdered sugar, and serve immediately.
