How to Convert Cake Flour to Self-Rising Flour

By Cathryn Chaney

Self-rising flour is a type of "soft" flour that contains added baking powder and salt. When speaking of flour, the term "soft" indicates a low-protein content. According to Nathalie Dupree in "New Southern Cooking," soft flours, including self-rising flour, are traditional in the American South where lower-protein winter wheat predominates. Cake flour is also a low-protein flour that you can convert to self-rising.

Careful measurements are important for converting cake flour to self-rising.

Step 1

Measure 1 level cup of cake flour into a mixing bowl. To measure accurately, spoon the flour into the measure and then level off the top using the straight edge of a butter knife or a wooden spatula.

Step 2

Add 1 tsp. of baking powder and 1/4 tsp. salt to the flour.

Step 3
