Donut Sugar

Donut sugar is a finely ground sugar, similar to powdered or confectioners' sugar, that usually contains a small amount of an anti-caking agent like cornstarch. This agent helps prevent the sugar from clumping and allows it to stick better to baked goods.

It is primarily used as a decorative dusting on donuts, pastries, and other baked goods to provide a sweet finish. The anti-caking agent helps the sugar maintain its powdery texture and prevents it from melting too quickly.

Donut sugar is primarily made of sucrose, which is generally recognized as safe (GRAS) by the FDA. The 2025-2030 Dietary Guidelines for Americans recommend no amount of added sugars, and at most 10 grams of added sugars per meal. JECFA has evaluated sucrose, and cornstarch (often used as an anti-caking agent) is also GRAS.
