i would not use granulated sugar while making buttercream icing. i would only use icing sugar. icing sugar usually has cornstarch mixed in with the powdered sugar. even if you added cornstarch to granulated sugar it would still give you a completely different texture than icing sugar...it would feel very gritty.
I would try using any other sugar you have. But if that's it, don't use as much as you would with powdered sugar because it could make it non-sweet dry and tart.
Granulated sugar shouldn't be used as a substitute where powdered sugar is specified in a recipe; granulated sugar will be too coarse.
In most things, No. Powdered sugar has cornstarch in it and has much less sweetening for the same amount.Clarification:Powdered (confectioners) sugar has only a minimal amount of cornstarch, which really doesn't affect the sweetness. The cornstarch is added to prevent the powdered sugar from lumping.But, as the answer above states, it usually cannot be used as a substitute for granulated sugar since it can result in the recipe not turning out as well.
If you put the granulated sugar into your blender & turn it into powdered sugar you can use it. Just blend the amount the recipe needs. Like, if it says 1 cup powdered, use one cup granulated. The problem with using regular sugar is - the frosting will sweat. It will look ok at first but when it sits for a while the frosting will look like it has water puddles on it. If you plan to eat it soon after its made, that would be ok. But it shouldn't sit for very long. You might want to find a recipe that uses regular sugar.
I guess you could - just use twice as much. But it might make the filling cloudy-looking. MUCH better to substitute the same amount of brown sugar (1 c. if the recipe calls for 1 c. of granulated sugar). Brown sugar has a hint of molasses that makes the pecan pie richer.
You can substitute powdered unflavored coffee creamer for powdered milk.
Granulated sugar shouldn't be used as a substitute where caster sugar is specified in a recipe; granulated sugar will be too coarse.
Of course, the result might not be the same however with concerns to the texture
I don't think many recipes that need powdered sugar would work with a substitute, but you can make powdered sugar if you have a food processor. Put granulated sugar in the food processor and a little corn starch (about one teaspoon of corn starch to one cup of sugar). Run the food process for several minutes checking periodically to see if the sugar is fine enough. When it's powdery you can use it in your recipe.
rwgular sugar is granulated sugar. the other kind is confectioner's sugar, or powdered sugar
Confectioners sugar and powdered sugar are the same, so yes, you are using the same thing regardless of what the recipe calls for.
Well first you go on line and find a recipe for a plain dohnut then you add powdered sugar
Cornstarch is added to confectioners (powdered) sugar to prevent the sugar from lumping, so the amount is quite minimal. And adding cornstarch to granulated sugar isn't what makes it confectioners sugar. Confectioners sugar is much finer and softer than granulated sugar, it has a texture much like that of cornstarch. So you would have to be able to grind granulated sugar into a very fine powder in order to make it like confectioners sugar.
