this one never fails for me........sorry don't do gramms..... set the oven to 180C......All in one large mixing bowl......8 ozs of SR flour, 8ozs castor sugar, 8ozs butter or marg, one and a half teaspoons baking powder, 4 eggs (medium or large) divide between two 7-8 inch cake tins and bake for around 20-25 mins, just above the centre of the oven or until the top of the cakes bounce back when gently tapped with your finger, avoid opening to oven before about 20 mins, allow to cool on a rack, and fill.............good luck
