What each ingredient does
- Sugar
- Sweetens the frosting and, when finely ground, dissolves quickly and helps it whip smooth.
The step that matters
Beating to the right stiffness. Beating incorporates air, making the frosting light and white. Overbeating past the target firmness can make it stiff and grainy, so stop once it holds its shape but still spreads easily.
