This is my favourite choc cake recipe, i have shared it with many people and they love it too. I am sure you could double up quantities if you need too.
175g (7oz) self raising flour
200g (8oz) caster sugar
1 x 2.5ml(1/2 tsp) salt
25g (1oz) cocoa
100g (4oz) marg
2 medium eggs beaten with
5 Tbs(75ml) evaporated milk
5 Tbs(75ml) water
few drops vanilla extract.
Sieve flour,sugar,salt and cocoa
Rub in margarine
Stir in eggs, extract and liquids. Beat well
Grease and flour 2x 20.5 (8") cake tins, not loose bottomed as the mixture would run out. Divide mixture between them.
Bake at 180c, gas mark 4 for about 30-35 mins.
Cover with icing when cool.
Although the recipe says to bake in 2 tins i usually do it in one 8" square one.
