No need to hunt for, or pay a lot, for grain-free powdered sugar. You can make it yourself, in seconds, with a high speed blender or coffee grinder! It is also corn-free, gluten-free, and can be made with the natural sugar of your choice.
Grain-Free, Gluten-Free, Corn Free Powdered Sugar
Powdered sugar–also known as confectioners’ sugar or icing sugar–is granulated white sugar that has been crushed to a powder and then combined with a bit of cornstarch (to prevent caking). When you need some powdered sugar (for a simple glaze or icing), few other things will do.
So what’s the solution if you:
cannot (or do not) eat grains (in particular, corn)
want to ensure that the powdered sugar is 100% gluten-free
prefer to avoid highly processed white sugars
You can solve the first two problems by searching high and low for one of the few brands of gluten-free powdered sugar (and then paying mightily once found).
Alternatively, you can resolve all three issues by making your own powdered sugar–in seconds–at home. Easy (check), cheap (check), and fast (check)!
Ingredients for DIY Grain-Free Powdered Sugar
To make your own grain-free powdered sugar, you will need the following ingredients:
The beauty of doing it yourself is that you control the type of sugar. For example, you can make powdered coconut sugar. Sure, it is tan instead of white (which may not be suitable for all recipeS), but wow, what a great flavor! Mix it with a bit of nondairy milk and you have an instant, caramel-y icing (yes, please!).
If you need a whiter powdered sugar, you still have less processed options, such as natural cane sugar. If processed sugar is not a concern, you can always stick with regular white granulated sugar.
Equipment for DIY Grain-Free Powdered Sugar
To make powdered sugar at home, you will either need a:
Blender (ideally high-speed, but traditional works, too)
Electric coffee grinder (wiped clean of any coffee residue)
The objective is to pulverize the sugar into powder, so the more powerful the equipment, the more powdery the result. A coffee grinder will take longer, since only a small amount can be pulverized at a time, but it can still produce great results.
How to Make Grain-Free Powdered Sugar
Place the sugar and the starch in the blender or coffee grinder.
For the coffee grinder option (as pictured below), grind 1/4 cup of sugar at a time. I add all of the starch in the first batch and then grind the remaining sugar (and then stir together all of the ground sugar at the end).
For blenders: Cover the container and process on the highest setting until powdery. It will take about 30 seconds in a high speed blender (about 2 minutes in a standard blender).
For coffee grinders: Cover and process, shaking the grinder to distribute the ingredients, until powdery (it will take about 2 minutes, max). Transfer to a bowl or container and repeat with the remaining sugar. Stir to combine all of ground sugar once finished.
And that, my friends, is that! You’ve got grain-free, cornstarch-free, gluten-free powdered sugar, ready to use immediately or store for future use.
How to Use Grain-Free Powdered Sugar
Use the grain-free powdered sugar as a measure for measure replacement for traditional powdered sugar. As mentioned above, the coconut sugar version is light brown in color. Use the cane sugar or regular white sugar option if a white powdered sugar is needed for the intended recipe.
