Pour sugar and cornstarch in to food processor, food chopper or blender. Turn on high until mixture is a fine powder.
Note: If your recipe calls for more than a cup, make some more!

How do you measure homemade powdered sugar? That is, when you grind up one cup of granulated sugar does it equal one cup of powdered sugar?

Wow. Did I learn a lot today! I was trying to save money by making my own powdered sugar and what I learned is that it's more money, and here's why! I learned this after I just went out and bought 6 bags on sale! The reason is because a 4 pound bag of granulated sugar would yield 10 cups of powdered, figuring your yield will be approx 25% more after blending, and a 2 pound bag of powdered sugar has 7.5 cups.
Let's take Aldi, for example. A 2 lb. bag of powdered goes for $1.29 which makes each cup worth slightly over 17¢. A 4 lb. bag of granulated goes for $2.49, which makes each cup worth just slightly under 25¢. Plus, the added cost of corn starch, electricity, and blade wearing on your blender. So, you're paying 33% less for the ready made. I never knew, and now I'm stuck with 6 bags of granulated, but at least it was on sale on the cheap for $1.69. Me and my crazy knack for figuring! Mad, at myself! Hehe!
But this is great to know in case you're in a pinch and the store is closed or you simply don't want to go to the store for one ingredient! The pic is some of the cuppycakes I make with my homemade buttercream frosting with powdered sugar!

How can I make powdered sugar for commercial purposes? What anti-caking agent can I use? I would also like to preserve the powdered sugar for up to 2 years. Any suggestions?

Can you explain in more detail what you mean for commercial use? I am fairly sure you can find out about making powdered sugar by doing an online search. I do know that powdered sugar is simply granulated sugar very finely sifted. Also, what do you mean by no caking agent? As for preserving it for up to two years it needs to be kept in sealed containers of some sort and completely kept away from moisture.
| Use equal amounts of granulated sugar for the amount of powdered sugar you want to make. Place the granulated sugar in a blender container and blend till fine. It's ready to use immediately.
There is no need to rush to the grocery just because you have no powdered sugar at home, for your recipe, just make it yourself! By Terri H. | |

| Is Confectioner's Sugar really the same as Powdered Sugar? I heard it contains some corn starch in it. I live in Germany, love american recipes and would LOVE to know what I can use instead of Confectioner's Sugar because I can't get it here. Thanks for any help!:) | |

| Hi, this was my original post. I've never heard of powdered sugar or confectioners sugar having any cornstarch in it. I, personally, haven't ever made this product in my blender, but my Aunt has made it and says it's just as good as the boxed, store bought stuff. | |

| Out of Confectionary Sugar (Powdered Sugar)? | 05/13/2005 |
| Here is a quick solution. Take granulated sugar and add 1 teaspoon of cream of tartar, and place in blender at high speed, until it reaches a powdery texture. | |

| Confectioners & Powdered sugar are the same, just depends upon what part of the country your from. I added about 1 tbsp per cup of sugar to my blender and it worked perfectly for my cream cheese frosting! | |

If you run out of confectioners (powdered) sugar. Take granulated sugar and pour in blender, and blend until it is powdery. You can do a cup or 2 at a time. Editor's Note: You need to add 2 Tbsp. of corn starch per cup of granulated sugar.

I want to learn how to make confectioners sugar.

It seems to have the same consistency to me. I use a vitamix so that might make the difference. (01/08/2009)

Powdered sugar can be made from regular sugar in a conventional blender. This way you don't have to buy two types of sugar or make a special trip to the store!

Blend 1 cup of granulated sugar in blender until desired powder is produced. Easy and much less expensive than store bought powdered sugar!
