So, can you substitute powdered sugar for granulated sugar in a recipe? The answer is: it depends! If you're making something like whipped cream or meringues, powdered sugar is the way to go. But, if you're making something like cookies or bread, you might want to stick with granulated sugar.
One fun fact: did you know that powdered sugar is often used to make marshmallows and cotton candy? It's true! The fine texture of powdered sugar helps to create that fluffy, sweet goodness. And, if you're feeling adventurous, you can even try making your own powdered sugar at home using a blender or food processor!
