This recipe is for a fluffy milk powder cake with a gentle sweetness of milk that spreads in your mouth. Mix egg yolk batter with water, skim milk powder, vegetable oil, and cake flour, then combine with meringue and bake in the oven. Once baked, spread a cream made by mixing fresh cream, condensed milk, and skim milk powder between layers of cake, cover the whole thing, and finally sprinkle with powdered milk to finish. This simple yet rich milk flavor cake is perfect as a snack or a gift.
