Egg white is the secret behind this fluffy frosting. When whipped over simmering water, it transforms into the most gorgeous white frosting you can imagine. The recipe makes enough for 6 cupcakes or 2 mini-cakes; it must be used right after it’s made because it starts to set up and harden.
Makes about 1 cup (16 tablespoons)
1. In a double boiler over simmering water (don’t let the bottom of the double boiler touch the water), with a handheld electric mixer on medium speed, beat the egg white, sugar, cream of tartar, and water until the frosting becomes very white and fluffy and soft peaks form, 3 to 4 minutes.
2. Remove the double boiler from the heat and stir in the vanilla. Use the frosting immediately before it starts to set.
