Icing sugar, also known as powdered sugar or confectioner’s sugar, is a staple ingredient in many baking recipes. It’s used to add sweetness and texture to a variety of treats, from cakes and cookies to frostings and glazes. However, have you ever stopped to think about what’s really in your icing sugar? Many people assume that all icing sugar contains cornstarch, but is this really the case? In this article, we’ll delve into the world of icing sugar and explore the role of cornstarch in this common ingredient.
What is Icing Sugar?
Before we dive into the topic of cornstarch, let’s take a closer look at what icing sugar actually is. Icing sugar is a type of sugar that has been ground into a fine powder. It’s usually made from granulated sugar that has been pulverized into tiny particles, making it easy to dissolve and incorporate into recipes. Icing sugar can be made from a variety of sugar sources, including sugarcane and sugar beets.
The Role of Cornstarch in Icing Sugar
So, why is cornstarch often added to icing sugar? Cornstarch serves several purposes in icing sugar. Firstly, it helps to prevent clumping and lumping, making it easier to store and use. Cornstarch is a natural anti-caking agent that absorbs moisture and helps to keep the sugar particles separate. This ensures that your icing sugar flows smoothly and evenly, making it perfect for dusting cakes and pastries.
Secondly, cornstarch helps to improve the texture of icing sugar. When you mix icing sugar with liquid ingredients, the cornstarch helps to prevent the mixture from becoming too thin or runny. This is especially important when making frostings and glazes, where a smooth and stable texture is essential.
How Much Cornstarch is in Icing Sugar?
The amount of cornstarch in icing sugar can vary depending on the manufacturer and the specific product. In general, most icing sugars contain between 3-5% cornstarch. This may seem like a small amount, but it’s enough to make a big difference in the performance and texture of the sugar.
Types of Icing Sugar That Don’t Contain Cornstarch
While many icing sugars do contain cornstarch, there are some types that don’t. Here are a few examples:
Organic Icing Sugar
Some organic icing sugars are made without cornstarch. These products often use alternative anti-caking agents, such as tapioca starch or potato starch. Organic icing sugars may be a good option for those who are looking to avoid cornstarch or prefer a more natural product.
Gluten-Free Icing Sugar
Gluten-free icing sugars are designed for people with gluten intolerance or sensitivity. These products often use cornstarch-free ingredients, such as rice flour or potato starch, to ensure that they are safe for gluten-free diets.
Specialty Icing Sugars
There are many specialty icing sugars available that don’t contain cornstarch. These products may be made with alternative sweeteners, such as honey or maple syrup, or may be designed for specific dietary needs, such as vegan or keto diets.
How to Make Your Own Cornstarch-Free Icing Sugar
If you’re looking to avoid cornstarch in your icing sugar, you can easily make your own at home. Here’s a simple recipe to get you started:
Ingredients:
- 1 cup granulated sugar
- 1 tablespoon tapioca starch or potato starch
Instructions:
- Combine the sugar and starch in a blender or food processor.

What is the purpose of cornstarch in icing sugar?
Cornstarch is added to icing sugar as an anti-caking agent. Its primary function is to prevent the sugar from becoming lumpy or developing clumps, which can make it difficult to work with. Cornstarch helps to absorb moisture from the air, reducing the likelihood of the sugar becoming sticky or developing an uneven texture. This ensures that the icing sugar remains smooth and easy to use in various applications, such as baking and decorating.
In addition to its anti-caking properties, cornstarch can also help to improve the flow and texture of icing sugar. It allows the sugar to be sifted or powdered more easily, making it ideal for use in recipes that require a smooth, even consistency. Overall, the inclusion of cornstarch in icing sugar is a common practice that helps to enhance its performance and usability.
Is all icing sugar made with cornstarch?
Not all icing sugar is made with cornstarch. While it is a common ingredient in many commercial icing sugar products, some manufacturers may use alternative anti-caking agents or produce cornstarch-free icing sugar. Additionally, some specialty or organic icing sugar products may be made without cornstarch, catering to consumers who prefer or require corn-free products.
It’s also worth noting that homemade icing sugar, made by grinding granulated sugar into a fine powder, typically does not contain cornstarch. This is because the grinding process breaks down the sugar crystals into a smooth, powdery texture, eliminating the need for anti-caking agents. However, homemade icing sugar may still be prone to clumping or becoming lumpy if exposed to moisture.
What are the alternatives to cornstarch in icing sugar?
There are several alternatives to cornstarch that can be used in icing sugar, depending on the desired properties and characteristics. Some common alternatives include tapioca starch, potato starch, and rice flour. These ingredients can provide similar anti-caking properties to cornstarch, while also offering distinct textures and flavors.
Other alternatives to cornstarch may include natural gums, such as guar gum or xanthan gum, which can help to improve the texture and flow of icing sugar. Some manufacturers may also use other ingredients, such as silica or calcium silicate, as anti-caking agents in icing sugar. The choice of alternative will depend on the specific application and desired characteristics of the icing sugar.
Can I make my own cornstarch-free icing sugar at home?
Yes, it is possible to make your own cornstarch-free icing sugar at home. One way to do this is to grind granulated sugar into a fine powder using a food processor or blender. This will break down the sugar crystals into a smooth, powdery texture, eliminating the need for anti-caking agents.
Another option is to use a natural sweetener, such as powdered coconut sugar or date sugar, which can be used as a 1:1 substitute for icing sugar in many recipes. These sweeteners often have a finer texture than granulated sugar and may not require the addition of anti-caking agents. However, keep in mind that these alternatives may have a distinct flavor and texture compared to traditional icing sugar.
