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

Hi Gemma!

I love love watching your videos! I love baking (Just a home baker☺️). Anyway, question, can you replace the granulated sugar with monk fruit sugar? My sister love her desserts but then she diagnosed as pre-diabetic, I just want this journey of her a little bit easy…

Thanks much and more power!
Karen
