6oz caster sugar
6oz stork
cream together until white (about 10 mins in electric mixer)
add 3 liightly beaten eggs one at a time and beat for a couple of minutes after each addition
add a few drops of vanilla extract
fold in 6oz of sifted self raising flour with a metal spoon until just mixed - do not beat or over mix at this point
split between 2 sandwich tins, whack in the oven at 160 degrees for 20 - 25 minutes until spongey and golden on top.
try really hard not to open the oven door until at least 20 minutes has passed, as cool air can make your cake sink. if after 25 minutes the cake isn't quite done, put it back in for 5 minute intervals.
let the sponge cool for 10 minutes in the pans then turn out onto a cooling rack cover it with a clean tea towel until completely cooled.
