Recipe Details

  • Yield: 3 cups (16 ounces)
  • Course:
  1. Remove butter from the refrigerator and cut into tablespoon-sized pieces. Leaving the butter out while you work on the next few steps gives it just the right amount of time to soften slightly (touching it will leave a tiny indentation) while still ensuring that it is quite cold.
  2. Place egg whites, sugar, and salt in a double boiler or the bowl of a stand mixer over a pot of boiling water.
  3. Whisk constantly until the eggs reach 160 F according to a candy thermometer (the temperature necessary to kill salmonella in raw eggs).
  4. Remove from heat and, in a stand mixer fitted with the whisk attachment, whisk on high speed for ten minutes or until the bowl cools to room temperature. If the bowl feels at all warm, keep whisking.
  5. Switch to the paddle attachment and, on medium speed, beat in the butter one tablespoon at a time.
  6. Turn the mixer up to high speed and keep beating until the frosting is light and fluffy. During this process, the gorgeous meringue will suddenly deflate and may look soupy or curdled. Just keep mixing and eventually it will come together again and become beautiful frosting (this can take up to ten minutes).
  7. Mix in vanilla.

Notes: Use immediately, refrigerate in an airtight container for up to one week, or freeze for up to 2 months.  Allow refrigerated or frozen buttercream to come to room temperature and then beat until it becomes light and fluffy again before spreading or piping on cakes.  Store cakes frosted with Swiss meringue buttercream in the refrigerator, but always bring to room temperature before serving.

  1. i wonder to make frosting at home does it really need to be a crusting buttercream?i want to try swiss onw but they say it doesnt is it important?i mean i wont be able to pipe designs on cake?i dont mind the top to be hard as long as i can do the designs i like or pipe names…..any ideas so i wont use usually powder sugar buttercream?i want to use less sugar

  2. I made this and it looked all cottage cheesey and curdled, and I thought it was ruined, but I googled a tip that if you take about 1/4 of the mixture out, pop it in the microwave for about 15 seconds until it's runny liquid, then slowly in a steady stream on low speed mix it back in, then back up to high, it will go all fluffy again!

  3. I have purchased alot of your baking tools….and I love them. But I'm struggling with coming up with an awesome buttercream that I can use under fondant. I just found your Swiss Buttercream recipe, so I will give it a try. Any tips you can share with your followers moving forward on using buttercream under fondant?
