Vanilla Frosting: Powdered Sugar

Powdered sugar, also known as confectioners' sugar or icing sugar, is granulated sugar that has been finely ground into a powder. It often contains a small amount of cornstarch, typically 3%, to prevent clumping and absorb moisture. It is derived from sugar cane or sugar beets.

Manufacturers add powdered sugar primarily as a sweetener and for its fine texture. It is commonly used in frostings, glazes, and icings, and as a dusting for baked goods, where it dissolves easily and provides a smooth finish.

Powdered sugar is generally recognized as safe (GRAS) by the FDA. It is a source of added sugars, which contribute calories to the diet. The 2025-2030 Dietary Guidelines for Americans recommend no amount of added sugars, and at most 10 grams of added sugars per meal. Excessive intake of added sugars is associated with various health concerns. JECFA has evaluated sugars and considers them safe for consumption within dietary guidelines.
