Did you know that confectioners’ sugar is actually the same as “icing sugar” in the UK, but in Australia they call it “soft icing mixture” and it sometimes contains vegetable oil? International sugar chaos. And here’s a weird one: if you run out of confectioners’ sugar, you can make your own by blitzing granulated sugar in a blender with a tiny pinch of cornstarch—but never cheap out on a dusty blender, or you’ll just get a face full of sugar fog and a fine layer of panic on your counter.
Another fun fact: a single tablespoon of confectioners’ sugar has about the same calories as granulated—so don’t tell yourself you’re being healthy. That’s like saying you went to a buffet for the ambiance.
The Verdict (Delivered with a Straight Face, I Swear)
Can you use confectioners’ sugar instead of granulated? Yes, but only if you’re okay with being a kitchen mad scientist who doesn’t mind a little unpredictability. If you need a crisp, stable structure—like in meringues, caramel, or crunchy cookies—run, don’t walk, to the store for granulated. If you’re making something soft and forgiving, like a frosting, a no-bake bar, or a recipe that already feels like a hug, the swap might just work.
My advice? Keep both in your pantry. Let them coexist like a grumpy cat and an overeager dog. Because in the end, sugar is sugar, but cornstarch is a traitor with a heart of gold—and knowing when they’re on your side is the secret to baking without tears.
