Can you replace caster sugar with icing sugar in baking cookies?

Answer 1

In some cases yes, but not if you're making icing. Icing sugar is far finer grained, and as such caster sugar will not be an adequate replacement in this case. (Your icing will be granular and not set properly).

You may be able to if it's a meringue recipe, but you'd be better off finding a recipe that does not use icing sugar to begin with.

Answer 2

You cannot substitute caster sugar for icing sugar if you are making icing......because icing sugar is more of a power an caster sugar is a grain (if you know what i mean) and icing sugar is used because it dissolves easily.i Hope that my answer has helped you!!

Answer 3

Yes, although for every cup required you need to double the amount of icing sugar. For example, if the recipe says 1 cup of sugar, you need to add 2 cups of icing sugar.

Answer 4

No because the caster sugar would not absorb the water, making it thicker until its icing.

Answer 5

yes but you have 2 put it in a blender then it will be the same

Answer 6

Not really - it's not fine enough. You could probably get away with it in buttercream, but it might taste a bit gritty.

Answer 7

No, it'll turn whatever it is you're baking into icing.
