6 banana peels (brown ones are fine)

1/2 cup water

4 eggs, separated

2 ½ cups white sugar

3 cups plain flour

75g butter

2 tbs baking powder


  • Preheat oven to 190°C
  • Grease a 20cm cake tin
  • Put the banana peels and half a cup of water into a blender or food processor. Blend them until they turn into a smooth, dark brown, aromatic mush. Set aside.
  • Beat the butter, yolks, and sugar in a mixing bowl until it is all combined —it should have the consistency of fluffy scrambled eggs.
  • Add the banana peels, the flour, and the baking powder, and mix well.
  • Whisk the egg whites until frothy, and gently fold into the mixture, careful to preserve the air
  • Pour into a cake pan. Bake for about 45 minutes, or until the cake passes the toothpick test.
