What is confectioners’ sugar?

Confectioners’ sugar is basically regular granulated white sugar that’s been pulverized within an inch of its life into a powder so fine it’s essentially sugar dust. But “sugar dust” doesn’t have quite the same air of sophistication as the name confectioners’ sugar.

Is confectioners’ sugar the same as powdered sugar?

Powdered sugar and confectioners’ sugar are not quite the same thing—even though the names are often used interchangeably. According to baking queen, Martha Stewart, confectioners’ sugar is made with cornstarch, which helps prevent clumping. Some bakers prefer true powdered to confectioners’ sugar because they believe the starch taints the flavor. If you agree with these sharp-tongued chefs, be wary, since you may even find “powdered sugar” in the grocery store that is actually confectioners’ sugar. Check the ingredients! 

Is icing sugar the same as confectioners’ sugar?

Yes, confectioners’ sugar and icing sugar are the same thing. Essentially, “icing sugar” is what folks in the UK call confectioners’ sugar, because it’s a common ingredient in icing. Sometimes language really is that simple. 

Does confectioners’ sugar expire?

Though it does eventually lose its luster, confectioners’ sugar can last for years if it’s stored in an air-tight container in a cool, dry place. 

How is confectioners’ sugar made?

Confectioners’ sugar is made by grinding refined white granulated sugar extremely finely. The grind is so fine that the sugar has a powdery or dusty consistency. It can be used to coat baked goods such as donuts or cakes, or you can use it to cover your face during your shift as a birthday party clown. (It’s a gig economy, folks. Take those jobs where you can get them!)
