Lots of home bakers wonder if they can swap out one type of sugar for another. It’s a common question, especially when a recipe calls for confectioners’ sugar and you only have powdered sugar in your pantry. The good news is, for most recipes, you absolutely can!
This guide will show you exactly how to make that switch so your baking turns out just right. We’ll cover everything you need to know.
Can I Use Powdered Sugar Instead Of Confectioners Sugar
It’s a question many bakers face: Can I use powdered sugar instead of confectioners’ sugar? The short answer is usually yes, they are the same thing! This can be a bit confusing because sometimes recipes specify one and not the other, leading people to think there’s a difference.
Let’s clear that up.
What is Confectioners’ Sugar
Confectioners’ sugar, also known as powdered sugar or icing sugar, is simply granulated sugar that has been finely ground into a powder. This grinding process also usually includes a small amount of anti-caking agent, most commonly cornstarch. This agent helps to keep the sugar from clumping and makes it smoother.
What is Powdered Sugar
Powdered sugar is the same thing as confectioners’ sugar. The name you see on the box often depends on the region or the brand. In the United States, it’s most commonly called powdered sugar.
In the United Kingdom and other Commonwealth countries, it’s usually called icing sugar. In some places, confectioners’ sugar is the preferred term.
The Key Difference (or Lack Thereof)
The primary difference people might perceive is the presence of cornstarch in most commercially produced powdered/confectioners’ sugar. However, the amount is very small, typically 3% to 5% of the total weight. This tiny addition is what gives confectioners’ sugar its smooth texture and prevents it from caking.
When a recipe calls for confectioners’ sugar, it’s usually for uses where a smooth, lump-free texture is important. Think about frostings, glazes, and delicate desserts. The cornstarch helps achieve this.
Why the Confusion?
The confusion arises because the terms are used interchangeably. If you see a recipe that simply says “sugar” and it’s for something like a cake or cookies, it usually means granulated sugar. But when it specifies “powdered sugar” or “confectioners’ sugar,” it means the fine, powdery stuff.
Many home bakers might have a box labeled “powdered sugar” and a recipe that says “confectioners’ sugar.” They might wonder if they need a special bag of “confectioners’ sugar” for their baking success. Thankfully, this isn’t the case.
When to Use Powdered/Confectioners’ Sugar
This type of sugar is ideal for:
- Frostings and icings
- Glazes for donuts or pastries
- Dusting baked goods like cookies or cakes
- Meringues and macarons
- Candies and confections
- Thickening sauces or fruit fillings
Making Your Own Powdered Sugar
If you find yourself without a box of powdered sugar but have granulated sugar and a clean blender or food processor, you can easily make your own. This is a great backup if you’re in a pinch.
How to Make Powdered Sugar
It’s a simple process. You just need to grind granulated sugar until it’s a fine powder.
- Measure your granulated sugar.
- Pour it into a clean blender or food processor. Make sure it’s dry.
- Blend or process on high speed. You’ll need to pulse it or blend for about 30 seconds to a minute.
- Shake the blender or processor and blend again until you have a very fine powder.
- If you want to add the anti-caking agent, you can add about 1 teaspoon of cornstarch for every cup of granulated sugar you started with. Blend it in thoroughly.
The texture might be slightly different from store-bought, especially if you don’t add cornstarch, but it works perfectly for most recipes. It might not be quite as smooth for super delicate applications like royal icing that needs to dry perfectly smooth, but for general frostings and dusting, it’s perfectly fine.
Can You Substitute Granulated Sugar for Powdered Sugar
No, you cannot directly substitute granulated sugar for powdered or confectioners’ sugar. They are fundamentally different in texture and how they behave in recipes. Granulated sugar is coarse and dissolves slowly, while powdered sugar is fine and dissolves quickly.
Using granulated sugar where powdered sugar is called for would result in a gritty texture and a different consistency for frostings, glazes, or other delicate mixtures.
Can You Substitute Powdered Sugar for Granulated Sugar
This is also generally not a good idea. Powdered sugar contains cornstarch, which affects its density and how it interacts with other ingredients. Substituting it for granulated sugar, which is pure sucrose without any cornstarch, would alter the moisture content, texture, and leavening in baked goods like cakes, cookies, and breads.
The result would likely be a denser, gummier, or overly sweet baked item.
Table Sugar vs Powdered Sugar
Let’s look at a quick comparison:
| Feature | Granulated Sugar (Table Sugar) | Powdered Sugar (Confectioners’ Sugar) |
|---|---|---|
| Texture | Coarse crystals | Fine powder |
| Main Ingredient | Sucrose | Sucrose + small amount of cornstarch (anti-caking) |
| Dissolving Speed | Slow | Fast |
| Common Uses | Sweetening beverages, baking cakes, cookies, breads, caramelizing | Frostings, glazes, dusting, meringues, macarons, candies |
Tips for Using Powdered/Confectioners’ Sugar
- Sift it For the smoothest results, especially in frostings and glazes, sift your powdered sugar. This removes any small lumps that might have formed and aerates the sugar, making your mixtures lighter.
- Measure correctly While it’s powdery, you can still measure it by scooping and leveling or by spooning it into your measuring cup and leveling. For very precise recipes, weighing it is always best.
- Adjust sweetness Because it’s so fine, it mixes in easily. Taste as you go when making frostings or glazes, as it can be easy to over-sweeten.
- Storage Keep powdered sugar in an airtight container in a cool, dry place. This prevents moisture from getting in and causing it to clump.
Common Baking Scenarios
Scenario 1: Making Frosting
A classic buttercream frosting often calls for confectioners’ sugar. You’ll cream butter, then gradually add the powdered sugar along with a liquid like milk or cream and vanilla extract. The fine texture of the powdered sugar creates that smooth, creamy consistency.
If you use granulated sugar here, your frosting would be crunchy and grainy.
Scenario 2: Glazing Donuts
A simple donut glaze is usually made with powdered sugar, a liquid (like milk, water, or juice), and maybe some flavoring. The powdered sugar dissolves almost instantly, creating a thin, smooth coating that sets up nicely. Using granulated sugar would leave your donuts with a sugary, gritty glaze.
Scenario 3: Dusting Baked Goods
For a delicate finish, dusting cakes, cookies, or fruit tarts with powdered sugar is common. You can use a sieve or a small fine-mesh strainer to get an even, light coating. This is where its powdery nature is essential.
Conclusion
The question, “Can I use powdered sugar instead of confectioners sugar,” has a very simple answer: yes. These terms are interchangeable, referring to the same finely ground sugar, usually with a touch of cornstarch. Whether you buy it pre-packaged or make it yourself, it’s a staple for achieving smooth frostings, glazes, and delicate finishes in your baking.
So next time a recipe calls for confectioners’ sugar, grab your powdered sugar with confidence!
