Do you have to have powdered sugar in icing?

Powdered sugar is commonly used in icing because it dissolves easily, creating a smooth texture. However, it's not strictly necessary; other sweeteners, like granulated sugar or honey, can be used, though they may alter the consistency and flavor. For a different texture, you can also use cream cheese or butter as a base, depending on the type of icing you want to achieve. Ultimately, the choice of sweetener depends on the desired taste and consistency of the icing.
