Classic White Frosting
- 2 ½ cups Whole milk
- ¾ cup All-purpose flour
- 2 ½ cups Sugar
- 5 Sticks unsalted butter, softened (2½ cups)
- 1 tsp. Pure vanilla extract
- Whisk together milk and flour in a saucepan. Cook over medium heat until thick and smooth, about 5 minutes, whisking often. Boil 1 minute to eliminate the starchy taste of the flour, whisking constantly. Transfer to a bowl and cover with plastic wrap, pressing it on the surface to prevent a skin from forming; chill until cold.
- Cream sugar and butter in a bowl with a mixer on high speed until light and fluffy, about 5 minutes. Add vanilla and chilled milk mixture, beating to the consistency of whipped cream, about 5 minutes.
