Powdered sugar, also known as confectioners' sugar or icing sugar, is a finely ground form of granulated sugar commonly used in baking and decorating confections. It is created by grinding granulated sugar into a fine powder, often with the addition of a small amount of cornstarch or another anti-caking agent to prevent clumping.
This ultra-fine sugar is favored for its ability to dissolve quickly and easily into mixtures, making it perfect for creating smooth icings, glazes, and frostings. In addition, powdered sugar is often used for dusting pastries and desserts to create a light, decorative finish.
When working with powdered sugar, most of the questions revolve around substitution with other types of sugar, incorporation into recipes, and avoiding lumps during preparation. The trickiest part about handling powdered sugar is often its tendency to clump which can lead to uneven sweetness in your dishes. Liquid clings to it more than other types of sugar which can cause lumps.
The secret to getting the most out of powdered sugar is to sift it before use. This will prevent lumps and ensure even distribution. A common hack to making your own powdered sugar at home is to blend granulated sugar in a blender or food processor until it reaches a powdery consistency.
It is also important to remember that powdered sugar is not a direct substitute for other types of sugar due to its fine texture and added cornstarch. Using it in place of granulated sugar may affect the texture of your baking.

Expiration & Storage Tips
When does powdered sugar expire?
Powdered sugar is a pantry stable ingredient, meaning it doesn't require refrigeration and can last quite a long time if properly stored. If unopened, it can last indefinitely. Once opened, when stored correctly it can maintain its best quality for about two years, but is still safe to use beyond that. As for homemade powdered sugar, generally, use same rule as traditional powdered sugar. As for freezing, it's not commonly recommended because it does not extend the shelf life. In addition, the moisture from defrosting could cause the sugar to clump together.
How do you tell if powdered sugar is bad?
Checking if powdered sugar has gone bad is relatively simple. Firstly, take a good look for any discoloration or growing spots which could indicate the presence of mold. You can also take a whiff; a foul or off smell can indicate spoilage. Lastly, taste it. If the sweetness has faded or if it tastes odd, it's time to toss it.
Tips for storing powdered sugar to extend shelf life
• Store powdered sugar in a cool, dry area, away from heat sources and moisture.
• Make sure to seal the container tightly after every use to protect it from humidity and pests. This helps prevent clumping and maintains freshness.
• If you're dealing with a large bag of powdered sugar, consider dividing it into smaller containers. This limits the sugar's exposure to air and contaminants each time you use it.
• If you detect any signs of spoilage, remember: when in doubt, throw it out. It's better to discard questionable sugar than to risk foodborne illness.
