Sub All Purpose Flour for Cake Flourの全貌を詳しく解説してご紹介します。

Let’s be real: your all-purpose swap will never perfectly match super-fine, bleached, commercial cake flour. It’s like using a good karaoke singer instead of Beyoncé—close enough for a Friday night, but not winning any Grammys. Your cake might be slightly denser, or have a slightly less delicate crumb. That’s fine. Nobody is judging you except your Aunt Carol, and she judges everything.

What's the Best Substitute for All-Purpose Flour?

Pro tip: if you’re making a recipe that’s hyper-delicate, like angel food cake or chiffon cake, just buy the real cake flour. Don’t be a hero. Those cakes rely on a paper-thin structure, and your cornstarch blend might betray you with a sad, flat soufflé.

For 90% of cakes—yellow, chocolate, pound, cupcakes—this substitution works like a dream. And if it doesn’t? Blame humidity. Blame your oven. Blame your neighbor’s dog barking at the wrong time. I’ll back you up.

The One Weird Trick That Actually Matters

Here’s the part chefs whisper: measure by weight, not volume. A cup of all-purpose flour can weigh anywhere from 120 to 150 grams depending on how aggressively you scoop it. Cake flour is lighter. So if you’re serious, grab a kitchen scale and weigh out 115 grams of all-purpose flour, then swap 15 grams for cornstarch. That’s your golden ratio. Now you’re a scientist who also eats cake.

But if you’re measuring by cups, just do the two-tablespoon swap and sift like a maniac. I promise, you will survive. Your cake might even taste better because you’ve infused it with smug satisfaction.
