Notes

  • You will need 200 grams of bananas for this recipe. Please don't be tempted to add more as it will change the texture of the cake.
  • The browner the bananas the better! Brown bananas help to give this cake its sweetness.
  • The baking time specified is for a 20cm round cake tin. You can use a different size/shape tin for your cake however please adjust the cooking time accordingly.
  • It is important to let the cake completely cool before icing with the cream cheese frosting, otherwise the frosting will melt and slide off if the cake is still warm.
  • It is important to use pure icing sugar for this recipe as this will help the frosting to hold its shape.
  • Although we encourage you to top this cake with cream cheese frosting, you can also top it with a simple plain icing.
  • This cake can be frozen (plain) for up to two months.
