Moist cake sponge is the “king” among other sponges. After all, it turns out not only airy, but also very juicy. You don't have to think about additional soaking of the cakes. Preparing a moist sponge cake for a cake is quite simple. You will need only 100 g of flour, almost the same amount of sugar and 3 eggs. The peculiarity of a wet sponge cake is that when preparing it, melted butter and heated milk are added to the dough. Milk must have at least 3.2% fat content, and butter more than 80%. In the end, it may seem that the biscuit turned out raw, but this is not so. Follow the moist cake recipe step by step.
