Swiss Meringue Buttercream is my FAVORITE type of frosting—it tastes delicious, is a dream to work with, doesn’t crust, and isn’t overly sweet or greasy. In short, it’s almost perfect!

The only problem? It can be a big pain to make. I won’t go into all the steps—for that, you’ll want to read my post on how to make traditional Swiss Meringue Buttercream. But the point is, the whole Swiss Meringue shebang has been a necessary evil…until now. Introducing  your new favorite recipe, The EASIEST Swiss Meringue Buttercream!

Traditional Swiss Meringue involves heating egg whites, then lots and lots of whipping. This recipe skips the heating step entirely, and still produces a rich, smooth, ultra-creamy buttercream with the characteristic texture and taste of Swiss Meringue. It’s as easy to make as American Buttercream, but it doesn’t crust over and it isn’t teeth-shatteringly sweet. You seriously NEED to try this recipe!

First things first: this is based on a frosting recipe by the amazing cake decorator Lauren Kitchens. If you want to see some real talent, check out her site! The frosting is not technically a Swiss Meringue, because the technique is different, but the ingredients and final product are so close, I have no problem calling this a lazy version of SMBC! I did a lot of tweaking and ended up with some very different ingredient quantities than the original recipe, to find the right balance of sugar + butter for my personal taste buds.

FAQ About the Easiest Swiss Meringue Buttercream

What piping tip do you use for these cupcakes?

It’s a closed star tip, Ateco #849. You can get the closed star tip here.

Is it safe to eat raw egg whites? / Do I have to use egg whites in a carton? 

I recommend using pasteurized egg whites for food safety reasons. Pasteurizing means the whites have been heated to kill the bad bacteria, so you can safely consume raw whites. If you cannot find pasteurized whites in a carton, look for pasteurized whole eggs, and separate out the whites yourself. If you cannot find either, and you personally feel comfortable eating raw egg whites, then you can use regular whites. OR just use this recipe for traditional Swiss Meringue! The whites are cooked in that recipe, so it is safe to use regular eggs.

A note about the ingredients: this recipe calls for pasteurized egg whites. IT IS SAFE to consume egg whites without cooking them, as long as you make sure that the whites you buy are pasteurized. To save time, I buy them in a carton–look for 100% egg whites, not liquid egg substitute. If you cannot find them in a carton, you can buy pasteurized eggs and separate them yourself. You’ll need about 5-6 large eggs to get the ¾ cup called for in the recipe.

Calories 250 kcal


  • 6 fl oz pasteurized liquid egg whites, (3/4 cup)
  • 24 oz powdered sugar, (6 cups)
  • ½ tsp salt
  • 24 oz unsalted butter, (3 cups), at room temperature
  • 2 TBSP vanilla extract


  • Combine the whites, powdered sugar, and salt in the bowl of a large stand mixer fitted with a paddle attachment. Mix everything together on low speed, until the sugar is moistened and no dry patches remain. Turn off the mixer, scrape down the sides and bottom of the bowl with a spatula, then turn the mixer to medium speed. Beat on medium for 5 minutes.
  • After 5 minutes, turn the mixer to medium-low and start adding the softened room temperature butter, 1-2 tablespoons at a time. Once all of the butter is incorporated, add the vanilla extract and mix it in. Stop the mixer and scrape down the bottom and sides once more. Turn the speed to medium and beat the buttercream for 10 minutes. At the end, you’ll have a frosting with a wonderfully light and creamy texture. It can be used right away, or stored in the refrigerator for up to two weeks, or the freezer for up to two months. If you have chilled the frosting, let it come to room temperature and then beat it for several minutes to smooth it out and restore its texture before using it.
  • To make chocolate buttercream, chop 12 oz unsweetened chocolate, and place it in a microwave-safe bowl. Microwave in 30-second increments, stirring after every 30 seconds to prevent overheating. Once the chocolate is melted, let it cool until it is completely room temperature. Make the frosting as described, and after it is finished, add the melted and cooled chocolate. Mix on low speed until the chocolate is completely incorporated.
