How to Make Italian Meringue Buttercream

When choosing between Swiss and Italian Meringue Buttercreams, the latter is definitely the one I prefer. Although it contains the same ingredients, Italian Meringue Buttercream is more airy and light than Swiss, which is the way I like a frosting to be.

Unfortunately, I think a lot of people are afraid of this recipe because it involves cooking sugar syrup. But you shouldn’t be! It’s not that hard, and as long as you have a candy thermometer and keep an eye on things, you shouldn’t have any trouble!

So, on with the buttercream!

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

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.

This recipe uses the same ingredients as the Swiss Meringue Buttercream:

However, before I start to explain things, I will make note of two exceptions. One is that the water is an ingredient in this recipe, and not hardware. It isn’t necessary and does slow the whole process down a bit, but because it helps the sugar dissolve more easily and evenly, I would not suggest leaving it out! The other is that there is an additional 1/4 c sugar in this recipe, but if you would like to leave it out and simply whip the eggs with a portion of the 1 c you will turn into syrup, that’s fine too!

5 egg whites at room temp
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). Also, it is important that the egg whites are room temperature for this recipe because room temp eggs have a more relaxed protein structure than cold eggs, which allows them to whip to a higher volume.
1 1/4 c (250 g) sugar, divided
This is granulated sugar. Do not use powdered sugar! You will be cooking 1 c and whipping the eggs with 1/4 c.
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…
1/2 c water

The hardware here is quite similar as well:

A rubber spatula
A stand mixer (with the whip attachment) or handheld mixer
A pot to cook the syrup in
Heavy bottomed is ideal, but I’ve never had a problem with any pans I’ve used. You want it to be fairly small so the sugar syrup comes up high enough to register on the…
Candy Thermometer
I really don’t think you should make this frosting without a candy thermometer. Cooking the sugar syrup to 245F allows the frosting to set a specific way (the syrup will form a firm ball when a drop is introduced to an amount of chilled water) with a structure ideal for holding onto air bubbles. And air bubbles are good – they make the frosting light! You can find one these all over the internet (Amazon) and at craft stores (Joann’s, Michael’s, Hobby Lobby, etc.)
Just know that if you are using a handheld mixer, and extra bowl for whipping the egg whites will be required.

The first step is to place your candy thermometer on the edge of the small pan you’ve selected for this recipe. Pour in 1 cup of sugar first, then pour the water over the top to moisten. Resist the urge to stir; it isn’t necessary and might cause sugar crystals to get stuck on the sides of the pan. These crystals could set off a chain reaction which would cause the rest of your syrup to become grainy and… Well, not what you want. Your frosting will taste good, but it will feel like someone poured sand in it if your syrup is not cooked properly.

So, how does one cook the syrup properly? Well, for starters, keep a close eye on it. Never leave the kitchen when you are cooking sugar, and be stingy with your time spent away from the stovetop. It is very important that you watch it or it may burn.
Another thing to do is to swirl the syrup. Don’t stir it or whisk it, just gently swirl the pan by the handle to ensure that the sugar crystals are evenly distributed and dissolved.

Trust me, I know it sounds scary, but it’s not bad! Just give it a shot – you might surprise yourself!

So, with these tips in mind, turn the heat up to medium and start cooking – but don’t stir!

While the sugar is cooking, pour the egg whites into the bowl you plan to whip the icing in, then wait for the syrup to come to about 230F-235F.

When it is within this range, begin whipping your egg whites. Start on a slow speed until they get frothy, then increase the speed to medium-high. Add the remaining 1/4 cup of sugar in a slow, steady stream just after the eggs begin to stiffen and continue whipping until the meringue no longer slides in the bowl. To test, simply lift and tilt your bowl. If the meringue slips, keep whipping. If you can hold the bowl over your head and the meringue doesn’t get in your hair, it’s ready.

Be very careful not to overbeat the egg whites. The dry, grainy whites will not smooth out through any amount of additional whipping and will only serve to detract from the texture of the finished buttercream.

Ideally, whipping the egg whites won’t take very long and will be done just in time for the sugar syrup to come to 245F, or the firm ball stage. If you think you will need more time, simply start whipping your eggs a little earlier. But PLEASE don’t whip them just as you start cooking the sugar syrup – they will deflate by the time the sugar has come to temp and won’t whip correctly.

Now, this is the part that scares some people: pouring the hot syrup into the whipped whites. It sounds terrifying, I know, but if you’re very careful (and perhaps have some help!) you will be fine!

Prepare yourself by turning the mixer on high speed and immediately begin to pour the syrup – at a very SLOW and STEADY speed – into the whipping egg whites. Aim for the spot just between the wall of the bowl and the edge of the whip (if using a handheld mixer, pour the syrup into just one area of the bowl and come at it from the side with the beaters. Be VERY careful not to get the syrup on your hands!). It’s ok if you get some on the side of the bowl or the whip, but it is best not to. The pieces that harden on either piece may break off and find their way into your icing, but it won’t be a disaster by any means!

Now that the sugar is added, just beat the icing for 10-15 minutes until it is sufficiently cooled.

(During this time I like to fill the pot I cooked the syrup in with water and bring it to a boil to remove the hardened sugar from the sides. Toss in the candy thermometer too, while you’re at it)

After the meringue has whipped, it will have the consistency of marshmallow fluff.

You could, if you were so inclined, stop here and simply frost your cake with this Italian Meringue. You can also pipe this out into various shapes and bake it for a few hours at a low temperature to make meringue cookies, but… That’s another post.

So start adding the softened butter, just as before, piece by piece with the mixer on medium. I like to count to 12 or 15 before adding each new piece, but just watch to make sure that each is fully incorporated before adding the next. Oh, and make sure that you scrape down the sides with the rubber spatula from time to time!

After all of the butter is added, turn the speed up to high. The whole process will take about 10-15 minutes, but you will begin to see the buttercream go through stages after all of the butter is added. First it will deflate and become soupy, then thicken, then curdle, then thicken to the final stage. If, for some reason your buttercream does not progress from the “soupy” stage (typically due to adding the butter too quickly or the butter/meringue being too warm), simply place your work bowl in the fridge for 7-10 minutes before whipping again.

After the buttercream is thick and luxurious, pour in your flavoring of choice (1 tsp of vanilla here!) and whip to combine.

And for the final step: try not to eat it all before you frost your cake!

Now, for notes (that may or may not have been copied from the Swiss Meringue Buttercream post)!

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.

If you have any questions, comments, or criticisms, please let me know! I will do my best to make this guide as comprehensive as possible!

I would like for my next how-to post to be about frosting cakes, but that might take some time. I’ve moved recently and… Well, let’s just say that there isn’t much counter space here…

    Nice post – Italian Meringue Buttercream is my favorite to make and eat!! You should mention that it&#39;s more stable than Swiss. Incidentally, you can heat the syrup as high as 250F – the higher the sugar syrup temp, the more stable the buttercream.<br /><br />Happy baking!<br /><br />:)<br />ButterYum

    I totally want to try this!!! It does seem like a lot of work but, as with most things, I&#39;m sure it gets easier with practice. Thanks for another great tutorial! Keep them coming!

  3. says

    I make mine same as yours with the sugar streaming into the whites the whole time while whipping but I&#39;ve noticed many tutorials for it suggest starting by pouring a small amount of the syrup on the whipped whites and beating and stopping and repeating the process till the syrup is used up. Never tried that way (scared it will deflate the whites too much pouring hot syrup over them in a big

    the meringue looks perfect. I really need to get myself a candy themometer, i accidentally bought a meat one instead…ive got some home made marshmallow mix waiting to be made :)<br /><br />Rose

  6. says

    @ Rose I have digital meat thermometer I use for my Italian meringue…doesn&#39;t make a difference I think as long as it gets to 240 degrees. I LOVE LOVE LOVE this icing and I thought it was hard to make before I tried it, such a misconception! I love it and make it every time I make a cake! Its heaven in a bowl!

  7. says

    Just found your blog and love the tutorial! I attempted this probably 18-20 years ago in high school and had a stringy candy mess so never tried it again. I think I will give it another go, as I just bought a candy thermometer. Question, is IMBC very soft, or is it pretty sturdy to use underneath fondant?

    I like that you&#39;ve shown pictures of each of the steps and stages. I&#39;m a very visual person. The first time I made imbc, I ended up throwing it out because I didn&#39;t know it was supposed to get soupy. Could you please put the number of servings your recipes make?

  9. says

    Hey guys. It seems like the recipe is still giving some of you trouble, and I am sorry to admit that I don&#39;t know why. I think it&#39;s likely that humidity is an issue or that the meringue is not allowed to cool sufficiently before the butter is added. In any case, I apologize for any difficulty that you are having.<br /><br /><b>@Crystal</b>: As long as you refrigerate it before

  10. says

    I refrigerated some of the icing, and when i took it out and tried to whip it again, it went into this horrible watery mess. What method do you use for refrigeration and re-fluffing?

  11. says

    Hey, Jasmine! There are a couple reasons that might be happening to you. Eggs will not stiffen in a plastic bowl, or if there are any traces of fat in the bowl you are using (including yolk – be sure there&#39;s none in the whites!). Room temperature egg whites also whip better than cold ones, so be sure you allow them to come to temp before using. I hope these tips help!

  12. Dani Nicole says

    YOu have renewed my faith in IMBC! I have made is successfully before plenty of times, but took a break from caking, and the last couple of times I tried IMBC, it failed horribly (actually now that I think about it, I just needed to continue to whip and I am sure it would have came together)…and tonight, tada! A lovely bowl full of yummy, light vanilla meringue awaits me…I mean awaits a cake,

    I just attempted Italian meringue buttercream using your tutorial and it came out PERFECT! It was really soupy as you said might happen, but 10 minutes in the fridge and it whipped up perfectly. The most delicious icing I&#39;ve ever had! Thanks for such a clear, well-written tutorial!

  14. says

    It finally, finally worked :) i had tried this recipe sometime around christmas and it was a mess but I figured I should give it another try. However, the egg/butter ratio never works for me. Maybe eggs in switzerland have a different size. I get them from a farm so they might be bigger. I had to add some more butter to the cream for it to curdle. But thank you so much for the recipe, the cream

  15. says

    Thanks for the great tutorial! Mine turned out a bit too sturdy and buttery and it didn&#39;t get fluffy despite all the whipping. Having made chocolate chantilly a few times, and having learned that the key to success is to get the fat content right, I presumed that maybe the mixture contained too much fat. After all, if you whip pure butter, it doesn&#39;t get very fluffy. So, to make the icing

    Still waiting for the right time to try this. <br />quick question though…. can I use powdered egg white for this recipe/the swiss buttercream?<br /><br />Made a white cake recentlyand the wasted egg yolks kinda made me sad :( .

    I spent the better part of 30 minutes with my friend trying to make this… it ended up looking like crumbly tofu in the end LOL. I&#39;m presuming it&#39;s because the liquid content was much too high — after all, the frosting sloshed around whenever we shook the bowl. However, when we drained away most of the liquid and re-whipped the frosting, it turned out okay again. Though given all that

    Thanks for posting this, I&#39;ve tried making swiss &amp; italian buttercreams that tasted good but never worked out too well on the cake. I&#39;m going to follow your steps exactly next time!<br /><br />Since this contains raw egg whites, would you avoid serving it to Pregnant people?

  21. says

    @anonymous, I&#39;m glad you got it to work eventually, but I&#39;m not really sure what happened. The amount of water shouldn&#39;t matter because the temperature that the sugar syrup is heated to indicates a specific concentration of sugar in relation to the water. As long as it is heated to the correct temp, there shouldn&#39;t be any variation from batch to batch in the amount of liquid

  22. says

    Thanks for the tutorial! It&#39;s incredibly clear, I have made Swiss Meringue Buttercream before and I had no troubles with it, I hope this one goes smoothly!<br /><br />I have a question though: Does this kind of frosting freeze well? I have heard that SMB freezes well, just wanted to know if that&#39;s the case with the italian version too :)<br /><br />Thanks a lot!

    Sadly this one didn&#39;t turn out well for me, I was determined to not giving up and I think I ended up beating it for more than a half an hour, crazy!<br />I have made Italian meringue before and I&#39;ve never had an issue with it, it was the butter that gave me problems. <br /><br />It was a VERY cold day.

    As my 2 year old son would say, &quot;I did it I saved the day!&quot; Whew, I conquered the meringue buttercream on my first try, thanks to your detailed tutorial! Unfortunately the cake stuck to the pan and is thus rather ugly (that&#39;s the last time I don&#39;t use parchment), but the frosting will make up for it. Delish!

    This was amazing! I loved every fluffy bite that I treated myself to before giving it away on a delicious cake to a friend. Thank you for the recipe :) And thank you for being so clear with your directions. Had I not first read about how it goes soupy to curdled to thick and delicious I probably would have thrown it out thinking I screwed up. So many thanks!! It&#39;s terrific :)

    Hi, I noticed your recipe has half the amount of butter than another recipe I&#39;m looking at, but all the other ingredients are the same quantity? Will the extra butter make it more heavy and dense? What can you tell me about this?<br />Also, could I use meringue powder instead of egg whites? (I need to make a huge number of cupcakes for my 21st, and eggs are just too expensive to buy just for

  28. says

    Breezs, I put in just enough butter to make the buttercream come together. I find that 1/2 of what is usually required does the trick. That way the buttercream isn&#39;t quite as bad for you AND it&#39;s cheaper to make.<br /><br />In regards to the egg whites, I don&#39;t know a thing about using powdered egg whites, but you can buy frozen egg whites and, if memory serves, they work just as

  29. says

    I really want to make this, but I&#39;ve been trying to find a recipe with weight measurements, particularly for the eggs. Egg sizes are pretty inconsistent, and what we call large in NZ is probably totally different to what you call large in America.<br />Do you have any idea of what weight the perfect amount of egg whites is?

  30. says

    Not sure why, but both times I tried the frosting—the cake turned out beautifully—it never came out of the &quot;soupy&quot; stage. I&#39;ve followed the directions down to the minute, but it doesn&#39;t seem to be working.

  31. says

    Hey Carson,<br /><br />My best guesses for the reason why the meringue may not recover from the soupy stage are the ones listed above: adding the butter too quickly or the meringue being to warm. I am sorry it didn&#39;t work for you :( I wish I could help more.

    Does the cake or cupcakes have to be refrigerated after using this, or can it sit out? I plan to make it a day before the birthday party.

    Hey Anonymous,<br /><br />I sometimes leave the cake/cupcakes out (and covered) overnight, but I also keep them in the fridge on occasion. Some people have concerns over the egg whites and the butter being out too long, but I&#39;ve never had trouble with it. Just make sure that the frosting is at room temp when you serve !

      You can use this under fondant, yes. THe best way to do it is to refrigerate the cake after frosting, then cover with fondant. Fondant-covered cakes should not be refrigerated (because they can &quot;sweat&quot;) but iced cakes can be refrigerated with no trouble.

    Morning all!! Just a comment on the water, although the other recipe for swiss cream leaves the water out, as the author said it aids in dissolving the sugar. But the process of getting the sugar to the 240+ degrees will evaporate that water anyway. As an avid maker of marshmallows and torrone I am very familiar with this process. So if you are comfortable in making this…for goodness sake,

    Wow, this turned out perfectly on my first go. Your instructions were excellent. Mine never got soupy, it just immediately curdled and then turned to buttercream.

Thanks so much for the great recipe.

    Thanks for the step by step guide. I&#39;ve done Italian meringue, but I don&#39;t think I&#39;ve done the buttercream before. Mine didn&#39;t get super fluffy after the curdled state, but I think I was comparing it to the pre-butter fluffiness. With mint oil, it&#39;s the perfect topping for a chocolate buttermilk cake.

    what is the difference between Italian merengue buttercream and just Italian merengue, what does the butter add to it? flavor or texture or what ? what is better for frosting cupcakes?

  65. says

    Hey there! The difference is just the butter. It adds flavor and texture, for sure. It just feels like buttercream, you know? I&#39;d definitely use this instead of just italian meringue for frosting cupcakes – Italian meringue is just very light and airy. I don&#39;t think it will add much to cake, unless you don&#39;t want a thick frosting!

    I just made this and my didn’t cone out smooth. It looks lumpy like whipped cream cheese but has a smooth texture when eaten. What went wrong? I’m at high elevation. Could that have something to do with it?

      Hey Regina,

      I don’t think elevation would have anything to do with it, no. How long did you beat it after adding the butter? I think it might just need 5 or so more minutes :)

    Hi. I just made it… unfortunately didn’t come very well. It became soupy as you said… I continued beating. As the cream didn’t get heavier I put the bowl in the fridge for several minutes. I beated again and the result was the same if not worse. Do you know what may happened? I’m so frustrated, honestly… I was doing it for my little girl first year birthday cake :(

      Sorry to hear that Natalia! Were the egg whites room temperature before you added the butter? If they were at all hot, they might have melted the butter :(

    I had a gal request that her buttercream cake not be so sweet, so i took to google :-) I just did a trial run of your recipe using your tutorial, and I DID IT!!! Next time my goal is to get less sugar syrup on my bowl haha but over all it went very well. I am such a visual learner so I really appreciate your pictures and step by step directions! Thank you so much for taking the time to do it!

    Hi, as for the butter, you didn’t indicate Salted or Unsalted butter. Is there any difference if I use either? Thanks in advance (:

    Very much detailed indeed.. I love the way it’s been addressed. I have tried the SMBC quire few times but not IMBC.

    I was wondering how the Italian meringue buttercream would react in a Mediterranean evening (temp 24 degrees C average)the lowest temp being 20C …icing to cover Wedding Cake …anxiously awaiting reply

      Hello Mairi-a,

      Unfortunately, I don’t have a lot of experience with this :( I would definitely ensure that the cake is thoroughly chilled, but then it would depend on how long you plan to have the cake outdoors. 20C might be fine, especially since it will be evening and there won’t be direct sunlight, but 24C might be pushing it because the butter could melt. I’m sorry I don’t have a more definitive answer :(
