Quickly make confectioners sugar from granulated sugar using a blender or food processor. Use as a replacement for powdered sugar in all your favorite recipes and treats!

I love it when I’m able to do something myself and save tons of time and money.
Like cutting a whole pineapple? That’s $5 saved.
Or making my own oat flour – that’s 30 minutes AND $3 at least because I’m not driving to the supermarket through busy traffic.
Even Homemade Apple Cider Vinegar. What else are you going to do with apple cores and peels other than throwing them away?!
For the same reasons, I’ve been making another baking staple for years – here’s how to make powdered sugar!
WHY YOU SHOULD MAKE CONFECTIONERS SUGAR
One of the best reasons to make confectioners sugar, or powdered sugar, is that you likely already have the two ingredients that you need to make it, so why not save yourself the money? It’s also:
- Fast
- Easy
- Healthier than store-bought
- Cheaper than buying it at the store…
- And did I mention you only need two ingredients?
- Plus, it’s a great kitchen trick to have up your sleeve when you need it!
I’ve used this homemade confectioners sugar for years in all sorts of recipes like Healthier Sugar Cookies and No-Bake Brownie Bites, and it turns out perfectly every time!
As we’ve lessened our sugar intake, we mostly stick to treats we make ourselves and keep them for special occasions. Sometimes it’s so nice to sprinkle a little powdered sugar on warm and toasty waffles as a special treat, don’t you think?!

HOMEMADE POWDERED SUGAR RECIPE INGREDIENTS
- Granulated Sugar. White table sugar, turbinado sugar, raw cane sugar, and even coconut sugar work.
- Cornstarch. Or use tapioca starch or arrowroot starch.
If you are using your homemade powdered sugar right away, you don’t need to add the cornstarch. It is there to absorb moisture and prevent clumping over time. If you’re making a larger batch to use multiple times, add the cornstarch to keep your confectioners sugar airy and smooth.as a special treat, don’t you think?!

HOW TO MAKE POWDERED SUGAR
Step 1. Combine the sugar and cornstarch in a high-powered blender, food processor, or coffee grinder and blend until the sugar is superfine and a fluffy powdered sugar.

Step 2. Use the sugar immediately or store it in an airtight container in the pantry for later.
Note: The more refined, whiter sugars make the fluffiest powdered sugar.

OTHER METHODS TO MAKE CONFECTIONERS SUGAR
- Use a food processor for confectioners sugar. If you don’t have a powerful blender, a food processor will work too. Depending on the capacity of your machine, you might have to make a bigger batch at one time for the blades to process it properly.
- Make icing sugar with a coffee grinder. Another option is a coffee grinder or spice grinder. Follow the same steps as above, adjusting the quantity to fit your coffee grinder. Be sure you clean your coffee grinder beforehand to avoid the transfer of flavors!
- How to make powdered sugar by hand (without a machine). A mortar and pestle would be the best option, but that’s very labor-intensive and time-consuming! It’s probably doable, but this isn’t going to be the best route.
CONFECTIONERS SUGAR ICING SUGAR TIPS
- The sugar will increase in size after blending. If you start with 2 cups of granulated sugar, you’ll end up with 3 to 3 ½ cups of powdered sugar.
- You CAN make powder sugar using just granulated sugar and skip the corn starch IF you are using it right away. The corn starch prevents it from clumping if you are storing it for later use.

DO REAL FOODIES EVEN EAT CONFECTIONERS SUGAR?
If we’ve been working on lowering our sugar intake, why even talk about making homemade powdered sugar?
Eating real food is a lifestyle. We’re not on a diet here, folks!
What we can do is make sure that our treats are made with simple, real food ingredients (like this 2-ingredient confectioners sugar mixture) and that we enjoy them intentionally and in moderation.
So we’re still going to make a yummy Chocolate & Peanut Butter Cake for a birthday. But I’ll have one slice with dinner that I track in my fitness app.
And if you usually have Cinnamon Rolls for Christmas breakfast, you should still enjoy that delicious tradition! (And make sure you’re still eating protein and produce alongside.)
You have plenty of options for including your favorite foods and sweet treats in a way that fits with your nutrition goals.

ICING SUGAR CONFECTIONERS SUGAR FAQS
Are confectioners sugar and powdered sugar the same thing?
Yep! Icing sugar confectioners sugar, and powdered sugar are all names for the same fluffy white sweetener.
How many cups are in a pound of powdered sugar?
One pound (which is 16 ounces) contains approximately 3 ½ cups of powdered sugar.
Can I substitute brown sugar for powdered sugar?
Probably not. Brown sugar contains molasses, which adds a dark, rich flavor and extra moisture to your baked goods. If a recipe calls for brown sugar, there’s likely a reason why!
Can you use regular sugar instead of powdered sugar in baking?
Not always! It really depends on what you’re baking, but as a recipe developer myself, there’s a reason why I would call for powdered sugar in a recipe. For example, the royal icing in my sugar cookie recipe would not have the right consistency if you were to use regular sugar. The same goes for a cream cheese frosting and dusting chocolate waffles!
Fortunately, you can make your own powdered sugar in a jiffy!

Hello, Thank you for recipe. I thought raw cornstarch can give you food poisoning? Doesn’t it need to be cooked before consuming? Thanks
Hi Chloe,
If you are planning to use the powdered sugar right away, you don’t need to add cornstarch. The small amount of cornstarch is listed in this recipe for texture / consistency if you don’t use it right away. Hope this helps.
Do i have to add cornstarch if i am using it for buttercream frosting and using it 4 days
Hi there, If you’re using this right away, you can skip the cornstarch! It’s there to prevent clumping over time from moisture. But if you don’t like corn, you can also try using arrowroot starch as well. Let us know how that goes for you!
Can I replace cornstarch with regular all purpose flour..I just dont have cornstarch now
If you’re using this right away, you can skip the cornstarch! It’s there to prevent clumping over time from moisture. 🙂
How long should I have to blend it? It’s been going for several minutes and hasn’t really changed???
Thanks for the recipe! Just curious, any thoughts on why corn starch is added?
Cornstarch is in store-bought powdered sugar, and it helps to prevent clumping. 🙂
