Take a bowl of an electric mixer that should be heat-proof. Add the sugar, corn syrup, water, and egg whites over water boiling in a saucepan. Make sure to constantly mix it for 2 minutes until the temperature reaches 160 degrees F.

Attach the bowl again and whip with the help of an electric mixer. Add the vanilla essence as soon as the frosting is glossy.

Your seven-minute frosting is ready.
