I'm bumping this one...
DH made the batter last night - I looked at it and said it looked a bit runny and couldn't see how the cakes would hold together. Well, in short, it was very difficult to make the cakes. We ended up making them quite small just so we could turn them over.
didn't do any tweaks, but this recipe needs some attention. They tasted great, but I wouldn't replicate this recipe - far too much trouble.
