Let's dig into these two different methods to make cakes. Creaming method, as the name explains, is a method in which ingredients are added one after another, creaming at each addition so that all the ingredients are incorporated well. In the all-in-one method, again as the term explains, all ingredients are added in a large bowl and mixed. I prefer and recommend the creaming method which helps to incorporate air and lightness to the batter. However, you may use the all-in-one method as well. It’s your choice.
