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.
Using Self Raising Flour Instead Of Plain
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.
