Ok so first off was the sponge mixture.Very simple sponge mixture but the trick with this was to beat the eggs and sugar in a bowl which was sitting in the sink with some water. I have never done it like that before but I will definitely try it again. Don't know if it made a huge difference, but seeing as I have never done it before and it was the best sponge yet, logic would say to try it again. Baked the cake and let it cool and I put it into the fridge to firm up a bit so it would be easier to cut.
The icing mixture was basic too. Cocoa, butter and heaps of icing sugar. When I say heaps, I mean HEAPS! It was just a matter of combining all the ingredients in a bowl over a double boiler.
Ok so the fun part was coating my lamingtons. Note to self though, the smaller the pieces of lamington, the more lamingtons need to be coated! It was lots of fun though and the end result was amazing. Dare I say, better than bakery quality lamingtons.
