How to Make Powdered Sugar in 30 Seconds (Yes, Really!)
It’s a tale as old as time. You’re halfway through a recipe for the perfect birthday cake frosting. The butter is impeccably softened, the vanilla is fragrant, and your spirit is high. You reach into the pantry for that essential bag of powdered sugar only to be met with… nothing. A vast, empty space where the sugar should be. Or worse, a sad, rock-hard clump that could be used as a weapon.
Before you throw your whisk across the room in a fit of baker’s rage or resign yourself to a naked, un-frosted cake, what if I told you the solution is already sitting on your counter? What if I told you that you are just 30 seconds away from a cloud of fluffy, perfect powdered sugar? Today, we’re learning how to make powdered sugar from regular old granulated sugar, and it’s so ridiculously easy it feels like you’re cheating at baking.
This isn’t a recipe; it’s a superpower. Let’s unlock it.
Why This “Recipe” is Awesome
Okay, calling it a “recipe” is a bit of a stretch. It’s more of a life-saving kitchen hack. Here’s why you need to know it.
- It’s an Absolute Lifesaver: This is your get-out-of-jail-free card. You will never again have to abandon a frosting recipe midway through. You will never again have to make a desperate, last-minute run to the store covered in flour. You hold the power now.
- It’s Incredibly Fast: I am not exaggerating when I say the entire process takes less than a minute. It takes longer to find your car keys to go to the store than it does to make a fresh cup of fluffy, perfect powdered sugar.
- It’s Actually Cheaper: While the savings on a single cup aren’t going to fund your retirement, granulated sugar is almost always cheaper to buy in bulk than powdered sugar. Over the course of a year of baking, this little hack can save you some serious dough (pun intended).
- You’re in Control: You can make exactly as much as you need, you know precisely what’s in it (just sugar and a little cornstarch!), and you can even make flavored or sugar-free versions.
Ingredients
Prepare for the shortest, most beautiful ingredient list in the history of baking.
- 1 cup Granulated Sugar: Just the regular white stuff you put in your coffee.
- 1 tablespoon Cornstarch: This is the secret ingredient! It’s an anti-caking agent that absorbs moisture and prevents your homemade powdered sugar from clumping back into a solid rock.
Tools & kitchen gadgets used
The hero of this story is one very important appliance.
- A High-Powered Blender: This is the most critical tool. A blender with a strong motor (like a Vitamix, Blendtec, or Ninja) is ideal for pulverizing the sugar crystals into a fine powder.
- A Spice Grinder or Coffee Grinder: This works amazingly well for making small batches! Just make sure it’s spotlessly clean, unless you want coffee-flavored frosting (which actually sounds kind of amazing).
- Measuring Cups and Spoons
- An Airtight Container: For storing your magical creation.
Step-by-step instructions
Ready? Blink and you might miss it.
Step 1: Measure Your Ingredients This is some complex, high-level math, so try to keep up. For every 1 cup of granulated sugar, you will need 1 tablespoon of cornstarch. That’s it. That’s the whole ratio.
Step 2: Place in the Blender Dump the sugar and the cornstarch into the canister of your high-powered blender or spice grinder. Don’t overthink it. Just get it in there.
Step 3: Blend into a Glorious Cloud Put the lid on the blender. Make sure it is on tightly. I am not joking. If you value a clean kitchen, ensure that lid is secure. Now, blend on the highest possible speed for 30 to 60 seconds. It will be loud. It will be powerful. It will be magical.
Step 4: Let the Dust Settle (CRITICAL STEP!) Your blender is now full of a swirling vortex of fine sugar dust. Do not, under any circumstances, immediately open the lid unless you want to create a sweet, sticky blizzard that will settle on every single surface in your kitchen. Walk away. Check your phone. Contemplate your genius. Just give it a full one to two minutes for the dust to settle completely.
Step 5: Check Your Work Carefully open the lid. The contents should look and feel exactly like store-bought powdered sugar—a fine, soft, delicate powder. If you can still feel any grit when you rub it between your fingers, pop the lid back on and blend for another 30 seconds.
Step 6: Store Your Creation Pour your beautiful, homemade powdered sugar into an airtight container. You are now a sugar wizard, capable of creating a key baking ingredient on demand. The power is intoxicating, isn’t it?

Common Mistakes to Avoid
This is almost impossible to mess up, but here are a few ways to get a less-than-perfect result.
- Using a Weak, Wimpy Blender: Your grandma’s blender from 1982 that struggles with a banana smoothie might not have the horsepower for this. You need a strong motor and sharp blades to properly pulverize the hard sugar crystals into a fine powder. A weak blender will just make… slightly smaller, sadder sugar.
- Skipping the Cornstarch: If you plan on using the powdered sugar immediately for a glaze, you might get away with skipping it. But for making frosting or for storing it for later, you must add the cornstarch. It’s what keeps the fine powder from absorbing moisture from the air and clumping back into a solid brick of sugar.
- The Premature Lid Opening: I cannot stress this enough. You will create a sugar-storm in your kitchen that you will be cleaning up for days. It will be in your hair. It will be on your dog. Let the sugary dust settle completely before you open that lid.
- Overheating the Blender Motor: If you need to make a large batch of powdered sugar, it’s best to do it in 1-cup increments. Running the blender on high for too long can cause the motor to heat up, which can then warm the sugar, potentially causing it to melt slightly and clump. Work in short, powerful bursts.
Variations & Customizations
Once you realize how easy this is, you’ll want to experiment. And you should!
- Keto / Sugar-Free Powdered “Sugar”: This hack is a game-changer for low-carb baking! Simply use your favorite granulated sugar substitute, like erythritol or monk fruit. Blend it up exactly the same way. You may not need the cornstarch, but a tiny pinch of xanthan gum can help with anti-clumping if you plan to store it.
- Flavored Powdered Sugar: This is so fun! Add a pinch of cinnamon, pumpkin pie spice, or a tablespoon of freeze-dried fruit powder (like strawberry or raspberry) to the blender with the sugar for an instant flavored version. This is incredible for dusting on cookies or French toast.
- Homemade Brown Powdered Sugar: Yes, you can do this! Just blend 1 cup of packed brown sugar with 1 tablespoon of cornstarch. The result will be a little moister than white powdered sugar, but it’s amazing for making caramel or brown sugar glazes.
FAQ Section
All your powdery, sugary questions, answered.
1. Can I really just make powdered sugar in my blender? Yes! As long as you have a powerful blender or a spice grinder, you can absolutely turn regular granulated sugar into powdered sugar in under a minute.
2. What if I don’t have a high-powered blender? A spice grinder or a clean coffee grinder is your next best option. They work incredibly well but can only handle small amounts at a time (think ¼ cup). A food processor is generally not powerful enough to get the sugar fine enough.
3. Do I absolutely have to add cornstarch? For the best, most authentic result that stores well, yes. Store-bought powdered sugar (in the US) contains cornstarch to prevent caking. If you’re making a small batch to use immediately in a recipe, you can omit it, but it might behave slightly differently.
4. How do I store homemade powdered sugar? Store it in a cool, dry place in an airtight container, just like you would with the store-bought kind. Thanks to the cornstarch, it should stay powdery and ready to use for months.
5. Is homemade powdered sugar the same as store-bought? Yes, it is virtually identical in taste, texture, and performance in recipes like icings and frostings.
6. How much powdered sugar does 1 cup of granulated sugar make? Because you’re breaking down the crystals and adding air, the volume increases. 1 cup of granulated sugar will yield almost 2 cups of powdered sugar.
7. Can I use other types of sugar? You can! You can blend coconut sugar, turbinado sugar, or brown sugar. Just be aware that they have a higher moisture content, so the resulting powdered sugar might be a bit more prone to clumping.
Final Thoughts
And there you have it. You’ve turned a potential baking crisis into a moment of pure, unadulterated genius. You now hold the power to create a key baking staple on demand. You are resourceful. You are brilliant. You are unstoppable.
