  • Invert to unmould, and carefully peel off the baking paper.
  • Allow to cool completely before cutting.


Superfine flour is extra fine low-protein flour. It is not plain flour or self-raising flour or cake flour. This flour is extra fine / light /soft so it produces lighter, softer, and finer sponge cakes.
However, you can substitute substitute with cake four if you don't want to purchase another bag of flour.
