Chocolate Mars Bar cake....(grab a chocolate cake mix and put it in a pan, then add mini mars bars into it before cooking)
or
Golliwog cake....(grab a packet or two of Golliwog biscuits, coat one side with strawberry jam and then dunk the other side quickly in rum and then whack some whipped cream on the same side. Continue doing that to all the biscuits as you sandwhich them to each other with the cream. Once all biscuits are stuck to each other, cover the entire thing in whipped cream and smash up some Flake chocolate bars and sprinkle that over it. Put it in the fridge to set and the hard biscuits will all soften up. Cut the cake on 45 degree angle to serve or it'll fall apart.
