Here’s the thing: powdered sugar is really just super-fine granulated sugar mixed with a tiny bit of cornstarch to keep it from clumping. That’s it. No secret factory, no unicorn dust.
When you grind regular sugar down into a light, fluffy powder, you’ve basically reinvented the stuff you buy in a box. It’s like turning a boulder into beach sand—same material, different vibe.
Your blender or food processor is your best friend here. You don’t need fancy equipment; just a clean, dry jar and a few pulses of the motor.
How to Do It (The Lazy Chef’s Guide)
Grab one cup of granulated sugar and toss it into your blender. Add one tablespoon of cornstarch per cup—this is what keeps your homemade powder from turning into a rock-hard lump later.
Blend on medium speed for about 30 to 60 seconds. Stop and shake the container halfway through, because sugar dust can get stubborn.
Open the lid, and whoa—you’ll see a cloud of white, fluffy powder that smells sweet and looks exactly like the store-bought kind. You just made powdered sugar in less time than it takes to find a parking spot.
