- 8 large egg whites
- 14 to 15 cups powdered sugar (about 3 3/4 lbs.)
Using electric mixer, beat 4 whites in medium bowl until very foamy, about 1 minute. Add 1/2 cup powdered sugar. Beat until well blended. Add 6 1/2 to 7 cups sugar, 1/2 cup at a time, beating until well blended after each addition and scraping down sides of bowl occasionally. Beat icing at high speed until very thick and stiff, about 5 minutes.
