if you;ve not seen it this is well worth a look- www.pimpthatsnack.com
essentially its a forum of people who decide to make there favorite snack BIG! particularly enjoy the creme de la creme egg and the monster custard cream.
Oh I love that site, when I was a student me and my kitchen mates in the halls of residence tried to recreate the pimped Jaffa Cake once... we ended up with a giant mess!!
