Heat the clarified butter in portions in a pan. For 3 pancakes (each approx. 10 cm Ø), add 2 tbsp. of batter each to the pan. Spread some banana slices and almond flakes on top. Fry the pancakes for about 2 minutes on each side.
Bake 9 more pancakes in the same way. Peel the rest of the banana and cut it into slices. Arrange the pancakes and banana slices on plates. Drizzle with maple syrup.
