A sprinkle of powdered sugar compliment these cream cheese lemon curd cookies.
Maybe you don’t use powdered sugar often and don’t want o give up pantry space you can just make what you need. And the best part is it only requires two simple ingredient and a food processor and you have it ready in about 1 minute.
HOW TO DIRECTIONS
To make powdered sugar at home, you’ll need two ingredients: granulated sugar and cornstarch. Use 1 tablespoon cornstarch for every cup of sugar.
You can make as little or as much as needed., add 1 tablespoon of cornstarch to each cup of granulated sugar used. Also this will double, so if only need one cup of powdered sugar, then use ½ cup of granulated sugar. Adjust the cornstarch in half also.
Add the granulated sugar and cornstarch to a food processor, and blend for 30 seconds, until the sugar is white and fluffy. If you want a much smaller amount, you can use a spice grinder.
Why Do You Need Cornstarch to Make Powdered Sugar?
Cornstarch is added to to prevent clumping. When sugar is ground into a fine powder, it tends to absorb moisture from the air, which can cause it to clump together. The cornstarch acts as an anti-caking agent, keeping the sugar light and fluffy.
How To Store
If you are not using right away, store in an airtight container. I like to use old mason jars. You might be interested in this blog post about using different sugar in cookie recipes.
Homemade Powdered Sugar
Ingredients
- 1 cup white granulated sugar
- 1 tablespoon cornstarch
Instructions
- Add the sugar and cornstarch to a small food processor and grind for about 30 seconds or until the mixture has reached the desired texture.
- Store in an airtight container like a small mason jar, store in a cool, dry area for up to 3 months.
Notes
- Because sugar is sensitive to moisture, so I do not suggest you freeze this recipe.
- Many spice grinders can be pretty small. If you have a smaller one, it’s fine to do it in smaller portions at a time.
- Food processors, unless they have a special setting for this, will not get the sugar fine enough to make powdered sugar.
- If your sugar still feels a little gritty and rough, you may need to grind longer, or get a grinder that grinds more finely.
