Okay, fine, life happens. You have a bag of self-rising flour and a deep craving for a tender cake. You can sort of make it work, but you’ll need to be a kitchen chemist. The trick is to reduce the leavener in the recipe to account for what’s already in the self-rising flour.
For every cup of self-rising flour you use, remove 1½ teaspoons of baking powder and ¼ teaspoon of salt from the recipe. Yes, you have to do math. Yes, it’s annoying. But your cake won’t taste like a science fair project.

Even then, the texture won’t be exactly the same because the protein content is off. You’ll get a slightly firmer crumb—think of it as a “tender biscuit-cake hybrid.” Still delicious? Probably. Perfect for a delicate ladyfinger sponge? No way, José.
A Little Pro Tip
If you ever need cake flour and don’t have it, the easiest DIY is to mix all-purpose flour with cornstarch. For one cup, take 2 tablespoons of all-purpose flour out, add 2 tablespoons of cornstarch, and sift it five times like a maniac. That gives you a low-protein replica without the leavening drama.
Meanwhile, self-rising flour is a one-trick pony that loves biscuits, pancakes, and scones—but hates being mistaken for its delicate cousin. Respect its boundaries, and you’ll both be happy.
