1. Sift and mix together the 5 dry ingredients. Beat together the
corn oil, milk and egg yolks. Beat the two mixtures together, like a
batter.
2. Beat egg whites until stiff. Fold into batter mix.
3. Pour mixture into a greased 20 cm cake tin, and bake at 180°C for
40 mins.
4. When cake is cold make topping by putting the sugar and water into
a saucepan and boiling slowly for 5 mins. Remove from heat, stir in
rum and pour over cake. If this is served as a pudding then serve with
whipped cream.
