Cream the butter and sugar until fluffy then add the beaten eggs and a few drops of vanilla extract, beating well after each addition.
Using a metal spoon fold in the flour gradually, adding a small amount of milk to create a dropping consistency.
Put the golden syrup in the bottom of the greased pudding basin and steadily spoon in the batter. Cover with parchment paper with a pleat in the centre to allow your pudding to rise, then cover with foil, also with a pleat. Tie securely with string and put in your steamer for 1½ hours.
Serve with custard, cream, or clotted cream.
