What Is Powdered Sugar
Powdered sugar, confectioner's sugar, or icing sugar are one of the same- granulated sugar pulverized with small amounts of cornstarch. Cornstarch acts as an anti-caking agent to prevent the fine sugar powder from forming large clumps.
This popular form of sugar is used in baking when a recipe calls for sugar that will dissolve quickly and provide a smooth consistency.
Uses For Powdered Sugar
Powdered sugar is the primary ingredient in icing, whipped cream, buttercream frosting, and fondant. Furthermore, it is used to make fudge, candy, cookies, cakes, and meringues, as well as decorate (or dust) baked goods. Powdered sugar is also used as a sweetener in coffee and tea since it dissolves instantly.
How Can I Make Powdered Sugar
Powdered sugar is made by taking granulated sugar like cane or beet sugar and pulverizing it with corn starch in a food processor to make a very fine powder. Granulated sugar is essentially transformed into a light and fluffy product.
- Homemade powdered sugar: Use 1 tablespoon of cornstarch for every 1 cup of sugar and blend.
Do I Need To Sift Powdered Sugar
Typically recipes will tell you to sift ingredients before or after measuring because it makes a difference in volume. The main purpose of sifting is to remove any large clumps and to aerate the ingredient.
A rule of thumb is to always sift powdered sugar before making icing or frosting to avoid a gritty texture. You can use a sifter, sieve, or whisk to sift powdered sugar.
Sifted sugar will be lighter and fluffier than unsifted, therefore, it will take up more space in a measuring cup.
- 1 pound = 4 ½ cups of sifted powder
- 1 pound = 4 cups of unsifted powder
Using The Spoon And Sweep Method
To measure powdered sugar, I would use the same method as granulated sugar and flour - the spoon-and-sweep method (aka the spoon-and-level method or scoop-and-level method)!
First, check to see if the powdered sugar has lumps, you may want to stir or sift the sugar first depending on what recipe you are making. After that, use a spoon to transfer the sugar to fill a dry measuring cup to the top.
Finally, use a straight edge to level off any excess sugar!
How Many Cups In A Box Of Powdered Sugar
Powdered sugar out of the box weighs 4 ½ ounces per cup. To keep it simple, if a box is 1 pound (or 16 ounces), it will have 3 ½ cups of powdered sugar.
In order to measure correctly, check if your recipe calls for sifted or unsifted sugar. Sifted sugar takes up more space in a measuring cup compared to unsifted, 4 ounces of sifted powdered sugar will equal 1 cup.
Please note that when you buy powdered sugar in a box or plastic bag, it will come unsifted. Rely on your recipe instructions to determine if you need to sift before or after measuring the confectioners' sugar.
- 1 pound box = 3 ½ cups of powdered sugar
- 1 cup = 4 ounces of sifted powdered sugar
- 1 cup= 4 ½ ounces of unsifted powdered sugar
Can You Substitute Granulated Sugar For Powdered Sugar
Granulated sugar should be not substituted for powdered sugar because the textures are completely different and produce unexpected results.
Regular sugar will not dissolve or mix well in icing or frosting recipes and will end up very grainy. However, you may switch sugars in some baked goods like cookies or brownies, so prepare to have different textures.
- Use 1 ¾ cup of powdered sugar per 1 cup of granulated sugar.
