MOTHER IN LAW SPONGE CAKE

MOTHER IN LAW SPONGE CAKE
1 cup cake flour,
3 tsp baking powder,
pinch of salt,
5 jumbo eggs separated, whites to be whipped stiff,
1/2 cup vegetable oil,
1/2 cup water,
200 g castor sugar,
11/2 tsp vanilla essence.
Method:
beat egg yolks and sugar until light and fluffy.  Add vanilla essence.  Sift dry ingredients and add in small amounts stirring into egg mix, add water and stir until all the flour is incorporated.  Stir in oil and lastly fold in the egg whites to the mixture trying to keep as much air in. Bake in preheated fan assist oven at 160 C or 180 C normal oven for 20 mins or until skewer comes away clean. This recipe I use for my cupcakes as well.
