Swiss Meringue Buttercream

Use this sweet buttercream recipe, adapted from "Martha Stewart's Baking Handbook," in our Chocolate-Peppermint Cake.

  • Yield: Makes 12 cups
Swiss Meringue Buttercream

Source: The Martha Stewart Show, December 2010


  • 12 large egg whites
  • 3 3/4 cups sugar
  • 4 1/2 cups (9 sticks) unsalted butter, room temperature, cut into tablespoons
  • 1 tablespoon pure vanilla extract


  1. In the heatproof bowl of an electric mixer set over a saucepan of simmering water, combine the egg whites and sugar. Cook, whisking constantly, until sugar has dissolved and the mixture is warm to the touch (about 160 degrees).

  2. Attach bowl to the mixer fitted with the whisk attachment. Beat the egg-white mixture on high speed until it holds stiff (but not dry) peaks. Continue beating until the mixture is fluffy and cooled, about 15 minutes.

  3. Switch to the paddle attachment. With the mixer on medium-low speed, add the butter several tablespoons at a time, beating well after each addition. (If the frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Stir with a rubber spatula until frosting is smooth.

    9 STICK OF BUTTER? Is this recipe correct?

    Oh My Gosh..I made this frosting today and added melted dark chocolate instead of worth it. My 4 year old daughter will attest to it. It really is delicious and maybe the best frosting I ever made!
