Homemade powdered sugar
identical to confectioners sugar
Make your own powdered sugar by blending granulated sugar with cornstarch in a food processor until it becomes a fine powder. This creates the exact same texture and sweetness as store-bought confectioners sugar.
- Best for
- frosting, glazes, dusting, all confectioners sugar applications, when you need exact texture
- Texture
- identical fine powder texture
Best substitute - blend in food processor until very fine powder, cornstarch prevents clumping and provides smooth texture.
Granulated sugar (direct)
identical sweetness
Regular granulated sugar can be used directly in some baking recipes where the sugar will dissolve completely, but it won't work for frostings or dusting applications.
- Best for
- baking, cookies, cakes, when texture isn't critical, when sugar dissolves completely
- Texture
- granular, may be gritty
Won't work for dusting or smooth frostings, only for baking where sugar dissolves completely.
Superfine sugar
identical sweetness
Superfine sugar is finer than regular granulated sugar but not as fine as confectioners sugar. It works better than granulated in some recipes but still won't work for frostings.
- Best for
- baking, cookies, cakes, when you need finer texture than granulated, when sugar dissolves completely
- Texture
- finer than granulated but still granular
Finer than granulated but not as fine as confectioners, better for some applications than regular granulated.
Caster sugar
identical sweetness
Caster sugar is finer than regular granulated sugar and works better in some baking recipes, but it still won't work for frostings or dusting applications.
- Best for
- baking, cookies, cakes, when you need finer texture than granulated, when sugar dissolves completely
- Texture
- finer than granulated but still granular
Finer than granulated, similar to superfine, better for baking than regular granulated sugar.
How it behaves in this recipe
Converting granulated sugar to confectioners sugar requires grinding it into a fine powder and adding cornstarch to prevent clumping. This is essential for applications like frosting and dusting where the fine texture is crucial. Direct substitution with granulated sugar only works in baking where the sugar will dissolve completely.
Tips for substituting confectioners sugar
10 tips- For the best results, always make homemade powdered sugar by blending granulated sugar with cornstarch
- Blend the sugar and cornstarch for at least 1-2 minutes to ensure it's fine enough for frosting
- Regular granulated sugar won't work for frostings or dusting - it will create a gritty texture
- Superfine and caster sugar work better than regular granulated in baking but still won't work for frostings
- When making homemade powdered sugar, sift it before using to remove any remaining lumps
- Store homemade powdered sugar in an airtight container to prevent clumping
- For royal icing, you must use powdered sugar or homemade powdered sugar - granulated won't work
- When dusting desserts, only powdered sugar or its substitutes will work - granulated will be too gritty
- For cream cheese frosting, powdered sugar is essential for smooth texture - granulated will be lumpy
- If you only have granulated sugar, make homemade powdered sugar rather than using it directly
Notes on confectioners sugar
- Make homemade powdered sugar by blending granulated sugar with cornstarch for the best results
- Use superfine or caster sugar for baking applications where you need finer texture than granulated
- For frostings and dusting, you must use powdered sugar or its substitutes - granulated won't work
- Consider using powdered erythritol or monk fruit as alternatives to confectioners sugar
- For royal icing, only powdered sugar or homemade powdered sugar will work properly
Questions
5 questionsCan I use granulated sugar instead of confectioners sugar?
It depends on the application. For baking where sugar dissolves completely, yes. For frostings, glazes, or dusting, no - you need the fine powder texture of confectioners sugar.
How do I make confectioners sugar from granulated sugar?
Blend 1 cup granulated sugar with 1 tsp cornstarch in a food processor for 1-2 minutes until very fine. This creates homemade powdered sugar that works exactly like confectioners sugar.
Why doesn't granulated sugar work for frosting?
Granulated sugar won't dissolve properly in frosting and will create a gritty, unpleasant texture. Confectioners sugar dissolves instantly, creating smooth, spreadable frosting.
Can I use superfine sugar instead of confectioners sugar?
Superfine sugar is better than regular granulated for baking, but it still won't work for frostings or dusting. You need the fine powder texture of confectioners sugar for these applications.
What's the difference between granulated and confectioners sugar?
Confectioners sugar is granulated sugar that's been ground into a fine powder and mixed with cornstarch to prevent clumping. This fine texture is essential for frostings and dusting applications.
