Sift flour, salt and baking powder together.
Beat eggs until light. Add vegetable oil. Add in sugar, milk and vanilla.
Add in the flour mixture and beat on medium for a few minutes.
Spoon batter over topping. Bake for 30 minutes or until skewer is clean.
After taking cake out of the oven, invert onto a plate. Leave the cake in the pan upside down for five minutes to make sure all the topping drops out of it before removing.
