How to Make Powdered Sugar - 2 ingredients and just 1 blender and you have instant Homemade Powdered Sugar

Hi Bold Bakers!

Did you know that powdered sugar, also known as confectioner’s sugar or icing sugar, is just blended sugar? It’s true and it’s that easy. You know those times when you want to make buttercream frosting and halfway through you realize you have no powdered sugar? Well, worry no more because my recipe for How to Make Powdered Sugar is coming to the rescue.

How to Make Powdered Sugar

  • First, you need a small powerful blender, like a spice grinder, nutri bullet, vitamix or food processor. I had the best success in a blender. You might have to try a few different appliances to see what works best.
  • Then add in the granulated sugar and cornflour (cornstarch). The cornstarch is important as it keeps the sugar dry.
  • Next, blend it all together until fine, around 4-5 minutes. Stop, and stir with a spatula to make sure to mix it around so that it is all getting blended.  
  • After a few minutes run it through your fingers and if it feels gritty then keep blending. You might still feel a little texture at the end but that’s ok. If you can’t seem to get it really fine you might need to try a smaller, stronger blender.
  • Store your Homemade Powdered sugar in an airtight container and it will keep indefinitely.

I used a coffee grinder and it worked great! First I tried it with my blender and it didn’t do anything at all but the coffee grinder only took about 30 seconds

The only time you really need to use cornstarch is IF you are making enough powdered sugar to store it. If you are making just enough for the recipe you are currently making, you do not need the cornstarch.

We just had to try this. Unfortunately, we did not have any cornstarch on hand. We decided to try just 1 cup of sugar in the “Bullet.” It definitely put a tug on the motor so we dumped it all out and used batches of 1/3 cup sugar. I was concerned that if we worked the Bullet too hard, it would generate too much heat and we’d either end up with cotton candy or just a mess! Well, it worked great. I plan to use it in whipping cream today and vacuum seal the remaining sugar. Since there’s no starch,… Read more »

Tip for those with a Vitamix- do not put it on high! It will liquify quickly. Not sure how I’m going to get the caramel-like mixture out of the container…

I always have icing sugar in my cupboards …… Not this time. I remember seeing your post on making your own and it worked like a dream. Thank you so much for sharing this brilliant idea.
