How Does Powdered Sugar Compare?

Powdered Sugar and granulated sugar are nutritionally similar, both consisting almost entirely of sucrose with roughly 387-389 calories per 100g. However, Powdered Sugar’s finer texture and corn starch additive (typically 3-4%) give it distinct baking properties, allowing for smoother frostings and glazes. When compared to honey or maple syrup, it is less nutrient-dense, though those alternatives contain trace minerals and offer different flavor profiles.
