Can you substitute powdered sugar with granulated in a frosting recipe?

You can substitute granulated sugar for powdered sugar in a frosting recipe, but it's not a direct swap and the result will be different. Here's why:

* Powdered sugar is finely ground and has cornstarch added. This gives it a smooth, velvety texture and helps it to dissolve easily in liquids.

* Granulated sugar is larger and coarser. It won't dissolve as readily and will leave a grainy texture in your frosting.

Here's what you can do:

1. Use a food processor to grind the granulated sugar. This will make it finer, but still won't have the cornstarch that powdered sugar does.

2. Add more liquid. You'll need to add extra liquid to your frosting to help the granulated sugar dissolve and create a smoother consistency.

3. Be prepared for a different flavor. The frosting might have a slightly more intense sweetness because the sugar isn't as finely ground.

For best results, it's usually recommended to use powdered sugar for frosting. If you don't have any on hand, try the methods above, but be aware that the results might not be exactly what you're expecting.
