Confectioner's sugar, also known as powdered sugar, is a finely milled white sugar with a soft, powdery texture that dissolves instantly on the tongue. It is pure carbohydrate, providing a quick burst of energy with no protein, fat, or fiber. Its hallmark is its ability to create a smooth, non-gritty sweetness in frostings, glazes, and delicate baked goods.

↓ Full nutritionPeople love it for its magical ability to transform simple desserts—turning a plain brownie into a bakery-style treat with a light dusting, or creating the silky, pipeable frosting on a birthday cake. It's the secret to that perfect, non-gritty sweetness in no-bake cheesecakes and French macarons.
It is nutritionally devoid, offering only 'empty calories' that can contribute to rapid blood-sugar spikes and provide no satiety. For those managing blood sugar or seeking nutrient-dense foods, it should be used sparingly. To counteract this, pair it with foods containing protein, fat, or fiber (like nuts, whole-grain cake, or fruit) to slow sugar absorption, and practice strict portion control by measuring it rather than dusting freely.
Most commercial confectioner's sugar contains about 3% cornstarch added as an anti-caking agent to prevent clumping, which is why it's not ideal for making clear syrups or candies where clarity is key.

What's the difference between confectioner's sugar and powdered sugar?
They are the same product. 'Powdered sugar' is the common term in the US, while 'icing sugar' is more common in the UK and 'confectioner's sugar' is a formal term used in recipes.
Can I make my own confectioner's sugar?
Yes. Simply blend regular granulated sugar in a high-powered blender or spice grinder until it's a fine powder. For a 1:1 substitute, add 1 tablespoon of cornstarch per cup of sugar to mimic the commercial product and prevent clumping.
Why does my powdered sugar clump in the jar?
Moisture is the culprit. Store it in an airtight container in a cool, dry place. If it does clump, simply sift it through a fine-mesh sieve before using to restore its powdery texture.
