It turns out, granulated sugar can be used as a substitute for powdered sugar in some cases, but not always. For instance, if you're making a cake or cookies, you can probably get away with using granulated sugar instead of powdered sugar. However, if you're making something like icing or frosting, you might want to stick with powdered sugar for a smoother texture.
Now, I know some of you might be thinking, "But what about the taste?" Don't worry, granulated sugar and powdered sugar have the same sweetness level, so you won't notice a difference in terms of taste. However, the texture might be slightly different, which could affect the overall appearance of your baked goods.
