Flour Facts - Cakes
All-purpose flour is the most commonly used flour and creates a good cake. Cake flour gives a more tender and delicate crumb. Self-rising flour contains the leavening agent and salts, so you only need to measure one ingredient. While you can substitute one flour for another, you will need to make some adjustments to the recipe.
For 1 cup cake flour, use 3/4 cup plus 2 tablespoons all-purpose flour.
For 1 cup all-purpose flour, use 1 cup plus 2 tablespoons cake flour.
