Can self rising flour be used to bake a cake if you do not have plain flour?

Self-rising flour contains baking powder and salt, which are essential ingredients for making cakes. Therefore, you can use self-rising flour in recipes that call for plain flour. However, you will need to adjust the amount of baking powder and salt that the recipe calls for. For a cup of self-rising flour, you should reduce the baking powder by 2 teaspoons and the salt by 1/2 teaspoon.
