Divide mixture evenly between 2 cake pans and bake for 45-50 minutes or until a skewer placed into the centre of the cake comes out clean.

  • This cake batter is VERY runny. Don't be concerned, it gives you a lovely moist cake.
  • To enable these cakes to have a nice flat top, I drop the batter-filled tins from about 20cm high onto the bench. It brings all the air bubbles to the top and gives you a nice flat topped cake.
