Out of powdered sugar? You can make your own at home. It's super easy. Repin to save!

Don’t you just hate it when you’re about to start cooking or baking, and you all of a sudden realize that you’re missing one crucial ingredient?

It’s not such a big deal when that certain ingredient isn’t the star of the dish.

But when you can’t make the dish without it – nothing is more annoying.

In these cases, it’s good to have a few food substitution tricks up your sleeve.

One such trick I learned a few months ago was to make my own powdered sugar (confectioners sugar). This technique has come in handy several times, specifically when I’ve needed powdered sugar for frosting and cookie recipes.

What Do I Need To Make Powdered Sugar?

Three things: Granulated sugar, corn starch, and a blender (or a food processor or even a coffee grinder).

The next time you find yourself in need of powdered sugar but don’t feel like running to the store, give this a try.

A Note About Corn Starch

I have made this several times without corn starch, and it works just fine. The texture is slightly different with the corn starch, more like what you buy in the store.

But for all intents and purposes, you can make homemade powdered sugar with just granulated sugar.

How to make homemade powdered sugar: Just 3 things you'll need to make this pantry staple at home.

Homemade Powdered Sugar

Yield: 2 cups
Prep Time: 5 minutes
Total Time: 5 minutes

The texture of this homemade powdered sugar is slightly different than powdered sugar you buy in the grocery store. It is slightly more grainy, but works all the same in a recipe. The trick is to blend or puree it long enough. I recommend using a four-blade device (such as a blender) instead of a two-blade device (like a food processor) for better texture and results.


  • 2 cups white granulated sugar
  • 1 teaspoon corn starch


  1. Place sugar and corn starch into a blender or food processor. Process until sugar becomes powdery, approximately two minutes or more.
  2. This recipe makes slightly more than two cups.
