Granulated sugar is the regular sugar we use in our daily lives, while powdered sugar is finely ground and often used for decorating and icing. The fine powder is much sweeter than granulated sugar, so you'll need to use less of it to achieve the same sweetness level.
Now, if you're thinking, "But what if I only have granulated sugar on hand?" Don't worry, you can still use it, but you'll need to make some adjustments. You can try blending the granulated sugar in a food processor to create a finer texture, but keep in mind it won't be as fine as powdered sugar.
This is where things can get a bit tricky. If you're making a recipe that requires powdered sugar, like a cake or cookie icing, using granulated sugar can result in a gritty texture. But, if you're making a recipe that uses sugar for sweetness, like a cake or muffin, granulated sugar will work just fine.
