Chocolate biscuit cake bribe (recipe attached)

Been making chocolate biscuit cake today. Took it to choir and placed it next to my sponsor form. Got loads of sponsors! Just made some more to take to work tomorrow, hope it works as well.
Chocolate biscuit cake is my speciality (the recipe is almost idiot proof);
1) Melt 1/2 lb (200g) plain chocolate with 4oz baking marg and 1tsb golden syrup in a pan on low heat .Do not boil.
2) Add 225g crushed rich tea biscuits and 1/2 cup of sultanas
3)Put into a lined swiss roll tin and compress with a fork.
4)Melt 300g milk chocolate in a bowl over a pan of hot water.
5)Pour over the biscuit maxture and smooth to a finish.
6)Place in fridge to cool.
7) After about 10 mins I flick over some melted white chocolate to make it look posh.
8) When cold chop up into small squares and eat till you feel quite sick!!
