This recipe is one of my favorites, it never disappoints, I use it very often in my cakes. The sponge cake is prepared with the addition of boiling water and vegetable oil, thanks to these components it has a moist and light texture. In my opinion, it doesn't need any additional soaking, it is moist, fluffy, and perfect in taste. Of course, it all depends on the cream you will use and your taste preferences. Highly recommended!
