I used a Magic Bullet and did batches of 1 cup each. It took about a minute per batch and the consistency and taste is exactly that of store-bought confectioner's sugar. Absolutely brilliant - will use every time from now on! PS - Someone below asked why there is cornstarch in it. It is because that is how confectioner's sugar is made and it will affect the outcome/consistency of your icing, etc. if you leave out the cornstarch. It is a necessary ingredient.

I ran out of powder sugar, so I thought this is a good time to try this out. Well I am 30 min into this and I am not even close. I don't know of I should give up or continue just to see what happens. My machine and the sugar are both hot so for now its just going to sit.

This saved my day! I did it in small batches in my blender as suggested by others and it came out perfect! I may never by Pwderd sugar again, this was so easy!

Yes you can make your own powdered sugar! I find it's easier to do in smaller batches in a smaller cup. I'm not sure why there is cornstarch added to this, though, it's not necessary.

Used 1 cup of white sugar & 2 Tbsp. Potato Starch in a coffee grinder & was done in less than 30 seconds. Have used it many times. I cant have corn so I use the potato starch, thats what powdered sugar was originally made with anyways. Turns out perfect every time, makes great icing.

Use a blender in small batches and will have much better results than a food processor. Almost undistinguishable from storebought.

Worked perfectly! I won't be buying powdered sugar again as this is too simple! Thanks!

I used a food processor and followed the instructions exactly.. I processed each small batch for about 5 minutes. It was almost like powdered sugar, but not quite. Then I tried to use it in frosting and it resulted in gritty butter that I had to throw away. I'll be sticking to store bought.
