Icing sugar, also known as powdered sugar or confectioners’ sugar, is a staple in many kitchens. Its fine texture makes it ideal for frosting cakes, dusting pastries, and sweetening beverages without leaving a gritty residue. While readily available in stores, making your own icing sugar at home is surprisingly easy, cost-effective, and allows for better control over ingredients. This guide will walk you through the process, offering tips and tricks to achieve the perfect fine texture every time.
Understanding Icing Sugar and Its Uses
Icing sugar isn’t just granulated sugar ground to a finer consistency. Most commercially produced icing sugar contains a small percentage of cornstarch (or sometimes tapioca starch). This addition serves a crucial purpose: it prevents the sugar from clumping together, which is a common problem due to sugar’s hygroscopic nature (its tendency to absorb moisture from the air).
Icing sugar is a versatile ingredient with applications beyond simple dusting. It’s essential for creating smooth, stable frostings like buttercream and royal icing. Its fineness allows it to dissolve quickly and evenly, contributing to the desired texture.
Here’s a brief overview of its common uses:
- Frostings and Icings: Provides structure and sweetness to buttercream, royal icing, and glazes.
- Dusting: Creates an elegant finish on pastries, cakes, and doughnuts.
- Sweetening Beverages: Dissolves easily in cold drinks without leaving a grainy texture.
- Thickening Sauces: Adds sweetness and body to certain sauces.
- Baking: Can be incorporated into some baked goods for a delicate crumb.
Choosing Your Sugar and Starch
The foundation of good icing sugar starts with the right ingredients. The type of granulated sugar you use will influence the final product’s flavor and color. Similarly, the choice of starch will affect its texture and stability.
Selecting Granulated Sugar
The most common type of granulated sugar is white granulated sugar, derived from sugarcane or beet. It’s highly refined and offers a neutral flavor, making it a versatile choice for icing sugar.
Cane sugar is another option, though it is essentially the same as beet sugar after refining. Look for options that are labeled as “pure cane sugar” if you prefer.
Organic granulated sugar is an increasingly popular choice for those seeking a more natural option. While it may have a slightly different flavor profile, it works well for making icing sugar.
Choosing the Right Starch
As mentioned earlier, starch is added to prevent clumping. The most common choice is cornstarch. It’s readily available, inexpensive, and effective at absorbing moisture.
Tapioca starch is another viable alternative, especially for those with corn allergies. It functions similarly to cornstarch and provides a smooth, clump-free icing sugar.
Potato starch can also be used, but be cautious as it can sometimes impart a slight potato flavor if used in excess.
The ideal ratio of sugar to starch is generally around 95-97% sugar and 3-5% starch.
The Grinding Process: Step-by-Step Guide
The heart of making icing sugar lies in the grinding process. A high-powered blender or a food processor is essential for achieving the desired fine texture.
- Measure Your Ingredients: Use a kitchen scale for precise measurements. For every cup of granulated sugar (approximately 200 grams), add 1-2 teaspoons (3-6 grams) of cornstarch or tapioca starch.
- Combine Sugar and Starch: Place the granulated sugar and starch in the blender or food processor. Ensure the container is completely dry.
- Grind in Short Bursts: Pulse the mixture in short bursts, 15-20 seconds each, to prevent overheating. Overheating can cause the sugar to melt or clump.
- Check the Texture: After a few pulses, stop the machine and check the texture. If the sugar is still grainy, continue grinding in short bursts.
- Sift the Sugar (Optional): For an even finer texture, sift the icing sugar through a fine-mesh sieve. This step will remove any larger particles or clumps that may have formed. Sifting is particularly useful if you are using an older or less powerful blender.
- Repeat Grinding if Necessary: If, after sifting, you find that the icing sugar is not fine enough, return the larger particles to the blender or food processor and grind again.
- Store Properly: Once the icing sugar is finely ground and sifted (if desired), store it in an airtight container in a cool, dry place. This will prevent it from absorbing moisture and clumping. A glass jar with a tight-fitting lid is an excellent choice.
Essential Tips for Achieving Perfect Icing Sugar
- Dry Equipment is Key: Ensure your blender or food processor is completely dry before starting. Any moisture can cause the sugar to clump.
- Pulse, Don’t Over-Process: Grinding in short bursts is crucial to prevent overheating and clumping.
- Don’t Fill the Blender Too Full: Overfilling the blender can hinder the grinding process and result in uneven texture. Work in smaller batches if necessary.
- Use a High-Powered Blender: A high-powered blender or food processor will produce the finest results. If your blender is less powerful, you may need to grind the sugar for a longer period and sift it multiple times.
- Adjust Starch Ratio: Depending on your climate and the humidity levels, you may need to adjust the ratio of sugar to starch. In more humid environments, you might want to add a slightly higher percentage of starch to prevent clumping.
- Cool Down Before Storing: Allow the icing sugar to cool completely before storing it. Warm sugar is more susceptible to absorbing moisture.
- Check for Graininess: Rub a small amount of the icing sugar between your fingers. It should feel smooth and powdery. If it feels gritty, it needs more grinding.
- Homemade vs. Store-Bought: Homemade icing sugar may not be quite as fine as commercially produced icing sugar due to the industrial processes used. However, it will be very close and offer the advantage of knowing exactly what ingredients are included.
Troubleshooting Common Issues
Making icing sugar is generally straightforward, but you might encounter a few common issues. Here’s how to troubleshoot them:
- Clumping: Clumping is the most frequent problem. It’s usually caused by moisture. Ensure your equipment is dry, grind in short bursts, and store the icing sugar in an airtight container. If clumping persists, try adding a slightly higher percentage of starch.
- Grainy Texture: If the icing sugar feels grainy, it hasn’t been ground finely enough. Continue grinding in short bursts and sift the sugar. You may need to use a more powerful blender or food processor.
- Melting: Overheating can cause the sugar to melt and form a sticky mess. Grind in short bursts and allow the blender to cool down between pulses.
- Uneven Texture: Uneven texture can result from overfilling the blender. Work in smaller batches to ensure the sugar is ground evenly.
- Starch Flavor: If you’re using potato starch, be careful not to add too much, as it can impart a slight potato flavor. Stick to the recommended ratio of 3-5% starch.
Flavor Variations and Additions
While plain icing sugar is a versatile ingredient, you can easily customize it with different flavors and additions.
Here are a few ideas:
- Vanilla Icing Sugar: Add a vanilla bean or a teaspoon of vanilla extract to the sugar and starch mixture before grinding.
- Lemon Icing Sugar: Add lemon zest to the sugar and starch mixture for a citrusy flavor.
- Chocolate Icing Sugar: Add unsweetened cocoa powder to the sugar and starch mixture. Start with a tablespoon and adjust to taste.
- Spice Icing Sugar: Add spices like cinnamon, nutmeg, or ginger to the sugar and starch mixture for a warm, festive flavor.
Experiment with different flavors and additions to create your own unique icing sugar blends.
Storing Your Homemade Icing Sugar
Proper storage is crucial for maintaining the quality of your homemade icing sugar. As mentioned earlier, it’s essential to store it in an airtight container in a cool, dry place.
A glass jar with a tight-fitting lid is an excellent choice. Plastic containers can also be used, but ensure they are airtight to prevent moisture from seeping in.
Avoid storing icing sugar in the refrigerator, as the temperature changes and humidity can cause it to clump.
If you notice any clumping, you can try sifting the icing sugar through a fine-mesh sieve to break up the clumps. If the clumping is severe, you may need to re-grind the sugar.
With proper storage, homemade icing sugar can last for several months.

What is the difference between icing sugar and granulated sugar?
Icing sugar, also known as powdered sugar or confectioners’ sugar, is granulated sugar that has been ground into a fine powder. Unlike granulated sugar, it typically contains a small percentage of cornstarch (around 3-5%) to prevent clumping. This cornstarch helps the icing sugar stay free-flowing and prevents it from sticking together, which is crucial for achieving smooth and even results in frostings, glazes, and dusting applications.
Granulated sugar has a larger crystal size compared to icing sugar, making it suitable for different purposes. Granulated sugar dissolves more slowly and is commonly used in baking cakes, cookies, and sweetening beverages. Attempting to substitute granulated sugar directly for icing sugar in recipes designed for icing sugar will often result in a grainy texture and an altered final product due to the difference in particle size and the absence of cornstarch.
Why would I want to make my own icing sugar?
Making your own icing sugar allows for better control over the ingredients. You can ensure that there are no unwanted additives or excessive amounts of cornstarch, especially important for individuals with corn sensitivities or those seeking a purer flavor profile. This also provides the opportunity to adjust the cornstarch ratio based on specific recipe needs, such as reducing it for a less dry frosting or eliminating it entirely if preferred and the sugar is stored properly.
Furthermore, making icing sugar at home can be a cost-effective alternative to purchasing it pre-made, particularly if you frequently use it in your baking. It also provides a convenient solution when you suddenly find yourself short on icing sugar while in the middle of a recipe. With a simple ingredient like granulated sugar and a readily available kitchen appliance like a blender or food processor, you can quickly whip up a batch of fresh icing sugar whenever you need it.
What kind of blender or food processor is best for making icing sugar?
While a high-powered blender or food processor will produce the finest and most consistent results, almost any blender or food processor can be used to make icing sugar. The key is to ensure that the appliance is completely dry before starting and to pulse the sugar in short bursts rather than running it continuously for an extended period. This helps prevent overheating and potential motor strain.
For smaller batches, a spice grinder can also be used effectively. However, ensure that the grinder is thoroughly cleaned and free of any lingering spices that could affect the flavor of the icing sugar. Regardless of the appliance you choose, patience is important. It may take a few rounds of blending and sifting to achieve the desired fineness, particularly with less powerful machines.
How much cornstarch should I add when making icing sugar?
A general guideline is to add 3-5% cornstarch by weight to your granulated sugar when making icing sugar. This translates to approximately 1-2 tablespoons of cornstarch per cup of granulated sugar. However, the ideal amount can depend on the intended use of the icing sugar and the humidity levels in your environment.
If you are in a very humid climate, you might consider using the higher end of the cornstarch range to prevent clumping. Conversely, if you’re using the icing sugar for a delicate application where you want to minimize the cornstarch taste, you can reduce it slightly or even omit it entirely, understanding that you might need to use the icing sugar quickly to avoid clumping. Experimentation is key to finding the right balance for your specific needs and preferences.
How do I prevent icing sugar from clumping after I make it?
The primary way to prevent icing sugar from clumping is to ensure it is stored properly in an airtight container. This prevents moisture from entering the sugar and causing it to solidify. A resealable plastic bag or a glass jar with a tight-fitting lid works well.
Another helpful tip is to add a desiccant packet, such as those found in vitamin bottles or electronic packaging, to the container. These packets absorb any excess moisture and help keep the icing sugar dry and free-flowing. Regularly shaking the container can also help prevent clumping by redistributing the sugar particles.
Can I make icing sugar without using cornstarch?
Yes, you can absolutely make icing sugar without cornstarch. Simply grind granulated sugar in your blender or food processor until it reaches a fine, powdery consistency. The resulting sugar will be pure and free of any additional ingredients.
However, be aware that icing sugar made without cornstarch is more prone to clumping, especially in humid environments. Therefore, it’s crucial to store it in a completely airtight container and use it relatively quickly to prevent it from becoming hard and unusable. Also, it may not behave exactly the same way in certain recipes where the cornstarch contributes to the texture.
How do I store homemade icing sugar to keep it fresh?
To maintain the freshness and prevent clumping in your homemade icing sugar, store it in an airtight container in a cool, dry place. A glass jar with a tight-fitting lid or a resealable plastic bag are excellent options. Ensure the container is completely dry before adding the icing sugar.
Avoid storing the icing sugar in areas with high humidity or temperature fluctuations, such as near the stove or refrigerator. Adding a desiccant packet to the container, as previously mentioned, can also help absorb any excess moisture. Properly stored, homemade icing sugar can last for several months.
