What each ingredient does

Cornstarch
Thickens the liquid into a smooth paste that gives the frosting body and a stable set.
Powdered sugar
Provides sweetness and bulk, becoming the frosting's main structure once stirred into the hot starch.

The step that matters

Cook the starch until very thick. Cornstarch must be fully heated in liquid to swell and gelatinize. If it is undercooked, the frosting stays thin and may not set properly once the sugar is added.
