What you need:
125ml (1/2 cup) butter or margarine
250ml (1 cup) castor sugar
2 large eggs
375ml (1 - 1/2 cups) self-raising flour, sifted
125ml (1/2 cup) milk
5ml (1 tsp) vanilla essence
1. Cream butter and castor sugar until light and fluffy.
2. Add eggs one at a time and beat well after each addition.
3. Fold in flour and milk alternately and add vanilla essence.
4. Pour batter into a lightly greased 230 mm round glass dish, the base lined with absorbent paper towel.
5. Place on an upturned saucer and microwave on 100% (high) power for 8 minutes. Allow to stand for 5 minutes (the sticky places on top will disappear), then turn out onto a cooling rack. When cold, ice and decorate as desired.
Orange gateau
To make this cake I used orange juice instead of milk, orange essence instead of vanilla essence. I then made an orange filling mixing 1 cup of fresh orange juice, 1/2 cup of water, 1/2 cup of white sugar. Then mixing
3 tbs of custard powder with 4 tbs of water, adding and microwaving on 100% (high) power, six to eight minutes or until thickened. Allow to cool completely. If you got any Cointreau add a dash, yummy!
You can top with orange flavoured butter icing, I found topping with a orange mock cream just made this cake special. I guess I should give you the recipe?
