Apologies for the blatant first world problem, but I've had an Xmas cake disaster. Cake been cooking all day, I had to take DC to a party so asked someone else to take cake out of oven at correct time, leave to cool for a while then remove from tin to cool on a rack. Santa's little helper did as was asked, but unwittingly removed greaseproof wrapping as well, so by the time I got home the cake was slowly spreading under its own weight. I desperately tried to salvage the cake by putting it back in its wrapping and tin, but it all fell to pieces as I was doing this. I am GUTTED 
Said 'cake' is currently in the tin with with a plate and weight on top in the hope that it will fuse back together overnight. Does anyone have any experience of this, and/or words of wisdom? Do you think my plan will work?
