  3. hi there, i tried making your recipe yesterday and it was a complete flop. The cake mixture was very watery (flowing) but nonetheless i still tried to pipe it and bake it. it turned out a little hard and it separated into two layers (bottom was like dense and top was more cakey)....it broke when i attempted to roll it up. What could have gone wrong? Also, i noted that your instructions said Add flour, milk powder, vanila...but there's no mention of milk powder in the ingredients list..could this be the reason? Please help advise. thanks. From Regina

    1. Hi Regina,

      Thanks for pointing out the mistake, there is no milk powder used for this recipe. This recipe, actually I modified from my Rainbow cake recipe from previous post.

      The batter should not be watery, it normally will be a bit thicker, but a bit loose than normal sponge cake due to more egg yolks are used.

      I had the same experience like you did when I first started baking using Sponge gel/Emulsifier ( please see my previous post : http://testedandtasted.blogspot.sg/2009/07/sponge-cake-with-cheese.html

      So I suspect it could be:
      - under beat the cake batter, normally it could take around 10-20 mins depend on the mixer watt capacity.
      - over stirring liquid ingredients (butter/oil), if stirred the melted butter in too fast or too vigourously, then the whole cake will be deflated (good tips learned from wendyywy)

      I would suggest you try the recipe again and I'm sure you will like it. Start with plain and lesser colour first.
      Hope this may help.
      Happy Baking!
