Here's coffee sponge with dark chocolate icing and white chocolate buttons and just chocolate to the right.
Simple vanilla sponge with custard filling (creme anglais if you're posh), covered in melted chocolate and decorated with white chocolate buttons.
A nice little April Fools Joke to play tricks on people. Salt instead of sugar, had it done many times. Bit dull on your birthday. Take note people!!
However this link is great. It shows you how to make what looks like a cup of coffee or hot chocolate which has spilled. You can then place it on a carpet or sofa and preferably play the joke on someone who is very houseproud. We had friends over this afternoon and we made some of these. They're drying out as I type. Can't wait to try them. Oops! Forgot they're for the children.
Also take a quick look at this at the Guardian.
