Instructions

  1. Combine the sugar, water and cream of tartar in a saucepan. Cook the mixture over medium-high heat until the sugar is completely dissolved and the mixture starts to bubble.
  2. Whip the egg whites and vanilla extract in a mixing bowl until soft peaks form. Slowly drizzle the hot sugar syrup mixture into the egg whites while whipping constantly at medium-high speed until stiff peaks form and frosting is very glossy, around 8-10 minutes.
