Can You Use Self Raising Flour Instead Of Plain
Okay, picture this: it's 9 PM on a Tuesday. You’ve had a horrible day, and all you want is to bake a batch of chocolate chip cookies to make everything better. You grab your trusty recipe, only to find it calls for plain flour. But when you open your pantry, staring back at you is a lonely bag of self-raising flour. Don’t panic. You’re not alone in this flour-based crisis, and I’m here to save your cookie dreams.
Let’s get the science-y bit out of the way, but super quick. Self-raising flour is essentially plain flour that has baking powder (a leavening agent) and a little salt already mixed in. Think of it as plain flour’s over-caffeinated cousin—it’s ready to party and puff up at a moment’s notice. Plain flour is just flour, no extra baggage. That one little difference is why your recipe might get weird if you swap them without a plan.
The Great Swap: When It Works (and When It’s a Disaster)
If you’re making something that already calls for a chemical leavener (like baking powder or soda), you can totally use self-raising flour—but you need to adjust. Imagine your recipe asks for one teaspoon of baking powder plus 2 cups of plain flour. Since self-raising already has baking powder, you have to skip the extra powder in the recipe. It’s like adding extra salt to a soup that’s already been salted—nobody wants that chemical aftertaste.

Here’s where it gets tricky. Self-raising flour has a fixed amount of leavening (usually around 1½ teaspoons of baking powder per cup). So if your recipe needs more lift than that, you’re stuck with a flat, dense result. Think of pancakes or scones: they need a precise rise. Using self-raising when the recipe asks for plain plus double the baking powder? Your baked good might rise too high, then collapse in the middle like a sad soufflé that gave up. Drama alert!
But What About Cookies? Please Tell Me About Cookies.
Ah, cookies. The reason we’re all here. For most drop cookies (like classic chocolate chip), you can actually get away with using self-raising flour if you tweak the recipe slightly. The key is to reduce the baking powder called for in the recipe to zero. But here’s the kicker: cookies usually rely on a balance of spread, chew, and lift. Self-raising flour can make them puffier and cakier than intended. You might end up with a cookie that looks like a muffin top—cute, but not the chewy, dense hug you were craving.
Pro tip: If you want to use self-raising flour in cookies, add an extra tablespoon of butter or a splash of milk. That helps counteract the extra lift. Experiment, but know that your grandma’s perfect recipe might just turn into a science project. And if you’re baking for a competition? Maybe stick to the original flour. No pressure, but your reputation is at stake.
The One Situation You Should Absolutely Avoid
Do not swap self-raising flour into a recipe that calls for plain flour and no leavening at all. Think pie crusts, shortbread cookies, or puff pastry. Those rely on zero chemical help—they get their structure from butter and technique. Adding self-raising flour to shortbread is like giving a quiet librarian a megaphone; everything gets loud, puffy, and wrong. You’ll get a crumbly, biscuit-like mess instead of a tender, melt-in-your-mouth circle of joy.
Also, be careful with yeast-based doughs like pizza or bread. Self-raising flour has baking powder that will activate before the yeast gets a chance to do its thing. The result? A weird, uneven rise that tastes more like a chemical lab than a rustic loaf. Trust me, I’ve made that mistake. It was not a proud moment.
The "I’m Lazy" Hack: How to Make Self-Raising into Plain
You can actually fix the problem if you’re stuck with self-raising flour but need plain flour. For every cup of self-raising, add two tablespoons of cornstarch (or arrowroot powder). Sift it together three times to distribute the starch evenly. This dilutes the baking powder and salt, making the flour behave more like plain. It’s not perfect, but it’s better than ruining a batch of croissants.
Alternatively, buy a bag of plain flour and keep it as your "emergency backup." Yes, I know you’re reading this while holding a bag of self-raising. I see you. We’ve all been there. The real answer is: read your recipe carefully. If it lists baking powder or soda as a separate ingredient, you can probably swap. If it doesn’t, run away from self-raising like it’s a bad boyfriend.
Final Verdict: Use It, But Don’t Be a Hero
So, can you use self-raising flour instead of plain? The honest answer is sometimes yes, with caution. For quick breads, pancakes, and scones—go for it. For delicate pastries, cookies that need structure, or any recipe without leavening—don’t. And always remember: baking is chemistry, but it’s also forgiving. If you mess up, you get to eat the evidence. That’s a win in my book.
Now go forth, bake your cookies, and maybe double-check your pantry next time. And if you do end up with muffin-top cookies? Call them "artisanal cloud cookies" and charge extra. You’re welcome.
