How to Make Swiss Meringue Buttercream

I receive A LOT of emails and comments about buttercream. I try to respond to them as thoroughly and promptly as I can, but sometimes I just don’t have the time to do so, and that makes me feel bad.

Like, really really bad.

So, what I decided to do was start a bit of a “how to” series on making different kinds of buttercream. I want to be able to address any questions that you guys may have, and be able to offer guidance with step-by-step photos just so you’ll feel a little bit more confident about trying out the recipes. I know that stepping away from the classic powdered sugar and butter frosting might seem a little scary, but it’s really not that difficult. European buttercreams may take a little longer to whip up and may make a little bit more of a mess, but trust me – it’s worth it. Swiss and Italian Meringue buttercream are less cloyingly sweet than traditional buttercream and, in my opinion, both have a more pleasant mouth feel.

Also, when you present a cake to someone and tell them that it’s frosted and filled with Swiss or Italian Meringue Buttercream, it makes you sound really fancy, and that’s always good, right? Especially since they never have to know that it’s not that hard to make!

So, let’s jump in, shall we?

How to Make Swiss Meringue Buttercream
A step-by-step guide penned by Kaitlin and photographed by P.

Swiss Meringue buttercream was the first European-style buttercream I ever made. It’s a little easier than Italian Meringue buttercream and it uses nearly the same exact proportions of ingredients. The taste is identical, but the difference is evident in the texture; Swiss Meringue Buttercream is a little less light than its Italian cousin, and feels a little heavier (but not oily!) on the tongue. Because it is thicker, I chose to use it for the Super Epic Rainbow Cake for structural stability.

The first thing you should do when starting any recipe is to gather your ingredients and hardware. Measure out everything before you start to be sure that you have enough and also to expedite the process. This is called mise en place, which is just a fancy French way to say, roughly, “everything in its place,” and it is very, very important.

Here we have…

5 egg whites
You must be sure that you are using LARGE eggs or the proportions will be off. Your frosting will not set correctly if you use larger or smaller eggs (unless you compensate for the difference, but most people, myself included, are too lazy to bother). The egg whites do not have to be room temperature for this recipe, but it will speed things up if they are.
1 c (200 g) sugar
This is granulated sugar. Do not use powdered sugar!
2 sticks (226 g) butter
This butter is room temperature and should be chopped into tablespoon-sized slices before continuing. You must allow your butter to set on the counter for at least 30 minutes before using or it will not incorporate correctly. If, however, you would like a shortcut, simply slice your butter into tablespoon-sized pieces and arrange them in one layer on a plate. Microwave for 5 seconds, flip over each slice, and microwave for 5 seconds longer if needed.
1 tsp vanilla extract
Well, this is more than a teaspoon’s worth, isn’t it? No matter; just know that you can use almost any kind of flavoring you like for buttercream. I will touch on this point later in the post…
An arbitrary amount of water
This is more hardware than ingredient, so… My bad. This water will be poured into the pan of your double boiler.

Alright, now that you have your ingredients ready, let’s move onto hardware.

We will be using…

A small pan and an accompanying bowl (not pictured – oops!).
If you have a double boiler, use it! I don’t, so I suffice by doing it this way. Be sure that the bowl fits well on top of the pan and doesn’t set too low in it.
A whisk
A rubber spatula
An electric mixer
You can use a hand-held model or a standing model. Or just a whisk if you’re crazy like P.

Begin by pouring an inch or two of water into the pan of your double boiler. If you are simply using a pan and a bowl, make sure that the bottom of your bowl does not touch the water. If this happens, your eggs will scramble and you will have to start again! After an appropriate amount of water has been added, bring it to a simmer.

Meanwhile, combine the sugar and egg whites in the bowl of the double boiler with a whisk. You are not trying to whip the whites at this point, so don’t worry about creating volume. Just be sure that they are evenly combined.

When the water is simmering, place the bowl over the pan. Whisking constantly, heat until the sugar is completely dissolved and the mixture is quite hot to the touch (160F on a candy thermometer), about five minutes. Be sure to scrape down the sides of the bowl every once and awhile with the rubber spatula to get all of the sugar off the sides of the pan. If all of the sugar doesn’t dissolve, your frosting will taste fine, but it will be grainy and won’t look smooth.

Heating the eggs and sugar has a few purposes. The first of which is that it melts the sugar, resulting in a very smooth meringue. And have you ever heard that room-temperature egg white whip better than cold ones? That’s because room-temp egg whites have a more relaxed protein structure in comparison to cold ones, and heating them further only loosens that structure more. This means that heating the eggs allows them to whip to a higher volume.

Also, cooking the egg whites can serve as a method of pasteurization if you have concerns about salmonella. Just use a candy thermometer to ensure that the egg whites reach 160F before continuing, and then continue as directed.

Anyway, the whole process should take about five minutes. To test if the sugar is dissolved, just dip your fingers into the mix (don’t worry – it’s not going to hurt you!) and rub some between your fingertips. If it’s gritty, keep cooking! If not, move on (after washing your hands, of course).

Pour the mix into a larger bowl (you may use the one from the double boiler, if you like, or a stand mixer if you have one), scraping the pan with the rubber spatula to get as much out as possible.

Begin whipping the egg whites on high speed. They will foam initially…

Then thicken slightly…

Then thicken some more…

And eventually you will have a lovely, glossy, light and wonderful meringue! It’s a lot like marshmallow, at this point, and quite stiff. The bottom of the bowl should be room temperature and the egg whites themselves should have cooled. The whipping will take ten to fifteen minutes.

At this point you can begin adding butter, but only after chopping it into tablespoon-sized slices (thanks, P!)

With the mixer on high speed, add the sliced butter, piece by piece, to the meringue. Be sure to add the butter SLOWLY and make sure that each pat is completely incorporated before adding the next (counting to 15 usually works for me). Don’t panic when the meringue deflates. That’s supposed to happen, and it’s totally fine!

Sometimes the buttercream becomes soupy after all of the butter is incorporated, and I have not been able to discern if that is due to adding the butter too quickly (which we did intentionally here) or if it is due to the butter being too warm. However, the cause is not terribly important, because I will show you how to fix it!

So, if your buttercream looks like this, don’t be sad, scared, angry or frustrated. It may look more like soup than frosting at this point, but it’s totally fine. All you have to do is…

Put it in the fridge. Seriously. Just let it cool for 5-10 minutes before you whip it again. You might also try adding a few more tablespoons of butter.

Of course, if your buttercream is not soupy, just keep whipping it.

But after whipping a little bit, the next “problem” may rear its ugly head. I know that that looks disgusting and curdled and just… Wrong, but it’s ok. Just keep your mixer and your spirits on high…

… And keep whipping! I promise that it will smooth out.

And when it does, it is time to add the flavoring of your choice. We chose 1 teaspoon of vanilla for today, just to keep things basic.

Then we whipped it in…

And wound up with a little over 2 cups of wonderful, luscious, smooth Swiss Meringue Buttercream!

Now, to address the topic of flavorings.

You may use any kind of extract you like in place of the vanilla. Almond, lemon, peppermint – you name it. It’s all to taste, so add more or less to your preferences. Oils are an option as well, but they are much stronger in flavor so only add a drop or two at a time. Melted chocolate can be used to make chocolate buttercream, but be sure that is has cooled sufficiently before adding it or it will make your frosting melt.

I like to use jams to flavor buttercream, but be sure that they are quite thick as too much liquid will cause the buttercream to break (meaning the fats and liquids to separate). I don’t know of any way to fix it when this happens, so be careful when adding jams and drop in about a tablespoon at a time.

Using jam as a flavoring will lend color to the buttercream, but that can also be done by using food coloring. Gel and liquid colors work well (I imagine that powdered food coloring would too, but I’ve never used it) and are best added just a bit at a time until the desired color is achieved.

Leftover buttercream may be kept in the refrigerator for a week or two or frozen, well wrapped, until needed. Just be sure to bring it to room temperature and whip well with a beater before using.

I think I have exhausted my knowledge of this subject for the time being, so I would love to open this post up to anyone who has any questions about Swiss Meringue Buttercream. If you’ve want to ask something, please feel free to do so in a comment, or e-mail me if you prefer! I’ll try to work the answers to your questions into the post if I’m able, or maybe I’ll just add a small FAQ.

At any rate, thanks for reading! I hope I’ve been able to make at least someone feel a little better about this whole process. Keep an eye out for the next “how to” which will focus on Italian Meringue!

Oh, and before I go – I would like to thank P’s family (Happy birthday to P’s mom!) for allowing P and me the opportunity to use their kitchen for this project, and I would also like to thank P for all of his help!

    I usually stick to the traditional butter and powdered sugar frosting, but have been dying to try this. I just have this hangup about wasting all those egg yolks.

      I just made a yellow cake from scratch that called for 6 egg yolks, then came to Pinterest to find a Swiss buttercream recipe that had (almost) 6 egg whites in it. (I guess I&#39;ll be scooping out a little of the whites to make it the correct ratio.)

  9. says

    I made swiss and italian meringue buttercreams quite a bit. I find that the swiss become soupy more easily for whatever reason. Another fix I&#39;ve found (in addition to refrigeration) is just add more butter. A lot of times another half stick or so of room temperature butter will make it firm right up.

  10. says

    This sounds so complicated but so yummy! And so well explained!<br /><br />Do you think you could give a weight measurement of the 5 egg whites because what we call large in NZ might be different to what you call large in America.

    Thank you for your tips!!! I made Italian Meringue buttercream for the first time today, and the meringue looked amazing until I added my butter – then it turned to soup! I put it in the fridge as u advised, and it made the IMC curdle. I took it out after half hr and beat it again and it managed to whip back into a silky fluffy buttercream! Hallelujahhhh! TQ!!

    This is amazing. YOU are amazing. Thanks so much. I have a few questions, if you have the time to answer: 1. Can you make this frosting (and the Italian Meringue, too) in advance and freeze it for re-use? 2. Is the purpose of the sugar in the recipe only to sweeten? I ask b/c I usually think frostings are too sweet for my taste, so I&#39;m wondering how much of the sugar I can cut without

    Hi Kaitlin, <br /><br />Ha! I only just now decided to read this! I used the swiss buttercream recipe from your rainbow cake post, which, by the way, doesn&#39;t mention the double boiler! I must have whisked and whisked and had my flame very low, because it came out perfectly, with no scrambled eggs in it at all!! Just thought I&#39;d let you know now that I noticed the discrepancy! Thanks again

  21. says

    Devorah, thanks for mentioning it, but you really don&#39;t need the double boiler. It just helps distribute the heat more evenly which I thought might be a boon to those making this frosting for the first time. I don&#39;t use one, myself :) <br /><br />I&#39;m glad that it worked for you!

    Veronica, I am happy to hear that you liked it so much! <br /><br />, it sounds to me like you might have had a bit of yolk in your whites. If there is any yolk (or fat of any kind) in the bowl at all, the whites won&#39;t whip. Maybe try again with a super-clean glass or metal bowl?

    Thank you for such a clear step-by-step. I am going to attempt the rainbow cake with meringue icing for my son&#39;s 1st birthday cake next month. Could you use white chocolate powder instead of melted chocolate? And if flavouring with chocolate, do you add it where you would normall add the extract? And one last question, roughly how much? Thanks!

    Yummy! It looks so pretty and glossy without the butter, what if I skip that step? Can I fill the cake with this deliciousness and cover it with fondant?

      I use store brand, usually. It might be that you aren&#39;t cooking the egg whites hot enough, or maybe that you&#39;re adding the butter too fast? Is the butter melty or just soft? You want it slightly firm, but warm enough to be smooshed if you press it with your finger.

    I LOVE this recipe and the rainbow cake and the combination of the buttercream with the cake is BEAUTIFUL!!

    Thank you so much for this recipe! About to attempt it tonight and just wondering if this will be enough to do a thin crumb coating and then full coating over a rainbow cake?!

    hi kaitlin. right now i&#39;m having problems with my swiss buttercream. it&#39;s soupy. i already added more butter and nothing changed. right now it&#39;s in the fridge. i hope when i whipped it again, it will be better :(

  63. Jessie says

    Oh no… the pictures didn&#39;t load so I was not sure what it should look like before I added the butter… and I did it TOO SOON!!!! Is there any way to salvage my cream? Its flat and looks like it will NOT stiffen or peak. :-( <br /><br />Ahh! I need Buttercream 911!!!!

    This is by far my favorite tutorial online right now – with your help and recipe i have successfully made swiss meringue buttercream twice. I am happy to report that I didn&#39;t encounter either of the problems mentioned above and everyone has commented on how amazing the frosting looks and tastes – thank you so much xxx

    love your blog. re the SMB, i&#39;ve tried the icing with the butter, but have never really enjoyed the flavour. when i was originally introduced to &#39;swiss meringue frosting&#39;, my friend stopped at the point where you add the butter, and iced her cake. delicious! so, just thought i&#39;d let you know it does work without the butter :) i love the marshmallow-like texture and the fact that

    This frosting is so yummy! The tutorial made it so easy. I made some last night and it turned out great. Well the second batch did, sadly, I didn&#39;t have my stand mixer and the cordless/rechargable handheld mixer just wasn&#39;t up to the challenge. But that was on me. :-) I added cream cheese at the end and it tasted so good and went well with the chocolate cake I made. <br /><br />And thanks

    Kaitlin,<br /><br />Thank you so much for posting this recipe! At first, I was a little intimidated by the instructions (I&#39;ve never used a double boiler before, and I didn&#39;t even know that there was one in the house until my mom pulled my grandmother&#39;s ancient double boiler out of the very back of the cabinet), but your step-by-step pictures and directions made it so easy– and it

    Hi! I&#39;m don&#39;t usually comment on recipes that I use, (is that considered bad manners??) but I just had to thank you! I was a little daunted by all of the steps when I first saw this recipe, but your instructions were so easy to follow and the trouble shooting tips were spot on. I made this buttercream (along with the rainbow cake) for my sons 1st birthday. It was a labor of love and

    Made this today for my daughter&#39;s first birthday cake-OH. MY. GOD! It is sooo good! And, I am pretty sure 90% because of this tutorial, it really wasn&#39;t hard at al! Anyone reading this who is scared because of the mention of the words &#39;double boiler&#39; don&#39;t be, that is a very easy, minor part of the process.

    I love your blog and am excited to make the rainbow cake and try the swiss buttercream for the first time, I&#39;ve always made the old boring wilton buttercream. Some advice – what type of buttercream is best for a humid environment? I live in Bermuda, where it is humid ALL the time, and my buttercreams often wilt. Would swiss or italian hold up better? Thx!

    Thanks so much for this tutorial. The 1st time I attempted turned out horrible, but after reading thru this my buttercream came out great.<br /><br />Thanks again

    I had the same problem as many others. Everything started out great until I added the butter, than I just ended up with soup! I even stuck mine in the freezer and nothing! It was crazy. I ended up adding like another stick of butter, but no help! I finally just dumped in a like an entire bag of powdered sugar and it helped quite a bit, but I finally gave up. I&#39;m not sure where in the world I

    Hi Kaitlin<br /><br />When I made this, the curdle stage did not happen and I didn&#39;t know when to stop beating. I just went on and on and for some reasons , the cream was a tad too liquified. Do you know what could be the reason for the dream not curdling ? Thank you

  85. says

    My first comment got lost. Anyway let me say it again I am really impressed with what you have presented here. If I can write 1/2 as beautifully and as exaustively as you I will be very happy with myself. Thanks I am pinning this up as I want to make it later. Right now I am looking for an eggless recipe. Any ideas? Thanks

  86. says

    Thank you for the great tips to overcome the disasters in between. I made a batch for my niece&#39;s christening and it got all curdled up. I was all depressed and thought its not my recipe to try. But I went through your tips and WOW!!! it came out perfectly and my aunt says it tasted like icecream, also holding the shape neatly.. Thank you once again.

  87. says

    This is a great tutorial! But I have a question. Not too long ago I heard of cupcake in a jar and I thought it would be the perfect gift for my friend. I wanted to know if when I make this buttercream frosting, will it break if left at room temp in a jar (along with the cake pieces)? I know the jar is sealed but I don&#39;t want it to look bad with oil seeping to the bottom and such. Any thoughts

  88. says

    This is thr first time i ever tried frosting in my life but turned out failure. Aftet double boiling i whipped for 15-20 min but it was soupy only, before adding butter. I do now what is wrong

  89. says

    Can you stop when you reached stiff peaks? I mean put everything away until its all at room temp? Or maybe put the merangue in the fridge before I put the butter. I think my mixer&#39;s whisk also heats up after beating the merangue. I use hand mixer too.

  90. says

    Thanks so much for this recipe! It is perfect. Not too sweet at all like most buttercreams. I doubled the recipe and it turned out perfect. I didn&#39;t have to add to the fridge. The only thing I can think of that I did differently is that I added the butter pieces at an extremely slow rate. I kept getting interrupted by my 2 toddlers so my stand mixer continued mixing until I could get back to

    i would never have dared to do this without your tutorial, thank you so much for sharing this and for going into every detail including what can go wrong. It may be beginners luck that nothing went wrong for me this time but I think it was all down to you and your wonderful explanation for every step of the way. By the way it is beautiful.

    I’m going to give this a try cause I always seem to have extra egg whites and can only make SO many meringues. I can’t make macarons (NOT macaroons) for the life of me.

    • says

      Oh how did it turn out?! It’s such a good way to use up egg whites. Have you ever tried angel food cake? That’s another tasty one. Dangerous though…. I can eat a whole cake myself! haha

  94. Auncott says

    I look forward to trying this recipe. I have only ever made regular buttercream I was wondering if it is possible to pipe with SMBC, specifically roses?
    Thanks from Canada.

    • says

      Hello Auncott! I don’t really like to pipe with SMBC. It isn’t as smooth as regular buttercream and occasionally “breaks” unexpectedly. I definitely recommend practicing with a batch first to see how you feel about it!
