The buttercream I used on these cupcakes is a meringue buttercream made with meringue powder. And it's light, fluffy and deliciously creamy. It's a simple, easy and effortless recipe using powdered egg whites instead of raw egg whites. Also, this meringue buttercream does not need any candy thermometer. Hence, it is a Swiss meringue buttercream with meringue powder.
Meringue buttercream with meringue powder is a great frosting recipe to use for those customers who are sensitive about using egg whites in their buttercream. And yet, they still want to have a meringue buttercream for their cake. I've mostly made these for pregnant moms. Since they are usually the ones who know I make this Swiss as well as Italian meringue buttercream with meringue powder.
So, if you need a meringue buttercream recipe that calls for meringue powder, use this recipe. Otherwise, stick to the traditional Italian Meringue Buttercream IMBC and Swiss Meringue Buttercream SMBC. You will find both of them right here on my blog.
How many types of buttercream are there?
I know the number of buttercream and frosting recipes can be overwhelming and sometimes confusing. In general, we can divide them into the following categories:
- Butter-based buttercream - Simple all-purpose buttercreams like my velvet American buttercream, Vanilla buttercream (eggless).
- Decorators buttercream - Often with all or some vegetable shortening to prevent the frosting from melting easily. For example, my Bakery style frostings - Vanilla and Chocolate Frosting.
- Cream cheese based - Made with cream cheese and with or without butter. For example, my classic cream cheese is made with butter, which adds more stability. And my no-butter cream cheese frosting is perfect when you want a more luxurious dessert type frosting.
- Meringue buttercream - Made with the addition of whipped egg whites. So it's less sweet than the classic butter-based buttercream. For example, my Swiss Meringue or Italian Meringue.
- Egg-based buttercream - Same as the French Buttercream and German buttercream made with egg yolks then whipped to make a light and fluffy frosting with the addition of butter.
- Whipped cream frosting - The lightest of them all is, of course, simple whipped cream. And I shared 5 different methods to make whipped cream at home. As well as a whipped cream buttercream frosting.
- Meringue buttercream with meringue powder - This here is Swiss meringue. And yet, I also have Italian Meringue Buttercream with Meringue Powder recipe.
Homemade meringue powder
- 10 tsp egg white powder
- ½ tsp cream of tartar
- And ½ tbsp cornstarch/cornflour
Before you start making meringue powder buttercream
- Always make sure your mixing bowl and whisk is cleaned and grease free. Since any fat in the bowl will not beat your eggs stiff. My practice – I rewash the clean bowl and whisk with warm water and soap. Wipe it with a clean kitchen towel. And take a paper hand towel, add a drop of vinegar to it, and wipe the inside of your bowl and whisk with this vinegar towel.
- Also, make sure your butter is soft. Cold butter will make a lumpy SMBC. And too soft (almost melted) will make it soupy. Best practice – take the butter out 20 minutes before you need it. Then, cut the butter into 1-inch cubes and leave it on the warm kitchen counter.
What is a double boiler method?
Basically, a double boiler is just two pans that fit perfectly together. One on top of the other. We often use this indirect heat method when we want to melt chocolate, or in this case, gently cook eggs with sugar. Since the steam caused by the boiling water in the bottom pan is just enough to melt the chocolate or egg without burning or overcooking it.
I wrote more about double boilers in a previous post - What is a Double Boiler Method?
Ingredients and substitutes (pin)
- Meringue powder - Quite simply we are replacing egg whites with egg white powder. You can buy meringue powder at most cake decorating stores. And yet, meringue powder can be expensive while egg white powder is more affordable. The good news is that you can also make meringue powder at home - I have given you the recipe above.
- Cream of tartar - This is present in the meringue powder and helps stabilize the egg whites.
- Sugar - I highly recommend using a fine grain sugar so the syrup comes to temperature quickly.
- Butter - I like using unsalted butter. And yet, if salted butter is all you have, go ahead and use it. I tried, and it still works.
- Flavoring - Vanilla is always my first flavor of choice. And yet, you can add any other flavoring that you need for the day.
Step by step instructions (pin)
- Cut the butter into cubes and set aside.
- Place water, meringue powder, and salt in a mixer bowl over a double boiler (explained above).
- Whisk the mixture until it's sticky and foamy - you want the mixture to resemble egg whites.
- Add the sugar and continue to whisk over the double boiler until the sugar is dissolved (about 160 F if you have a thermometer).
- You don't need a thermometer just make sure the sugar is almost dissolved.
- Place the bowl on a stand mixer and whip on high speed until you have a thick white meringue with glossy peaks.
- Gradually add the butter, one cube at a time, with the mixer running on medium speed.
- Once all the butter is in add the vanilla.
- Turn the mixer up to high and whip for two full minutes.
- The buttercream should be thick, creamy and glossy.
Storage
- Meringue buttercream will keep at room temperature for a few hours in any weather. And, I know those who enjoy good weather are able to keep Swiss meringue buttercream out for up to 2 days.
- It should be treated like butter. And if left out in high temperature or humidity it will melt just like butter.
- Also, it can be kept refrigerated for up to one week or in the freezer for up to three months.
- When frozen it is best thawed in the fridge overnight. Then, whip with a paddle attachment for about five minutes to restore consistency.
Using meringue powder buttercream
If you’re wondering if there is a difference between the two. Yes, there is!
This Swiss buttercream made with meringue powder is similar to regular SMBC made with egg whites, and yet a bit softer in consistency. So, you can use it the same as regular SMBC. While I prefer my stiff buttercream recipe for piping flowers.And, if I pipe flowers with this buttercream, then I freeze them as soon as I make the flower. Since once frozen, they hold their shape better when thawed.
How to make more Swiss meringue buttercream flavors
Dark, milk or white chocolate Swiss meringue buttercream
Add 200 grams melted and cooled chocolate to 4 cups of SMBC. And combine well.
Caramel Swiss meringue buttercream or salted caramel SMBC
Simply add 1 cup caramel sauce to 4 (to 6) cups of SMBC. For salted add a tbsp of rock salt. Combine well.
Butterscotch Swiss Meringue Buttercream
Add 1 cup butterscotch sauce to 4 (to 6) cups of SMBC. For salted add a tbsp of rock salt. Combine well.
Lemon Swiss meringue buttercream
Just add ¼ tsp lemon juice to 4 (or 6) cups buttercream. You can also add up to ½ if you want a very lemony buttercream. And, 1 tsp of zest can also be added if you don't mind the zest in the buttercream. In addition, ¼ tsp lemon extract will enhance the flavor even more.
Orange Swiss meringue buttercream
Add ½ cup orange juice, and ¼ tsp orange extract to 4 (or 6) cups buttercream. And 1 tsp orange zest can also be added.
Fruit flavors - blueberry Swiss meringue buttercream, or try raspberry SMBC, blackberry SMBC, strawberry SMBC
Add 1 cup fruit puree to 4 (or 6) cups buttercream. I love adding a fruit filling instead, which makes it slightly sweeter, and yet also more rich and vibrant in color.
Dulce de leche Swiss meringue buttercream
Simply add 1 cup dulce de leche to 4 (6 cups) buttercream.
Coffee or espresso SMBC
Dissolve 1 tbsp coffee in ¼ cup hot water or use ¼ cup espresso. Cool completely, then add to 4 (or 6) cups buttercream.
Mocha SMBC buttercream
Add 200 grams melted and cooled chocolate to 4 (or 6) cups coffee SMBC.
Peanut butter SMBC
Add up to 2 cups peanut butter to 4 (or 6) cups buttercream.
Tips & troubleshooting Swiss meringue buttercream
- The eggs got curdled - If using a homemade double boiler, make sure the water in the bottom pan does not touch the top pan. You want the steam to touch the pan, not the water. Makes sense? Also, monitor the heat or you will end up with scrambled eggs.
- My buttercream is grainy - Be patient and give the eggs and sugar time to dissolve on medium-low heat. Because, if you crank up the heat you will have sweet scrambled eggs, and also end up with a grainy buttercream since the sugar is not dissolved.
- My buttercream is greasy - When whipping the warm eggs, start on medium and move to high speed. Let the meringue whip to stiff peaks. Because, if not, they will lose volume when you add butter giving you a very greasy buttercream.
- Also, make sure the meringue is COOL before you add the butter. Check twice or even four times, and if you are not sure don't add the butter - give it a minute or two more.
- My buttercream is soupy - If butter is added too early, the warm meringue will melt the butter and turn the mixture into a meringue soup. DON'T PANIC. Just place the whole mixer bowl in the fridge for 15 to 30 minutes. And then whip it again. If necessary, place it back in the fridge to cool.
- Soupy buttercream - 99% of FAILED SWISS MERINGUE BUTTERCREAMS ARE A RESULT OF ADDING BUTTER TOO EARLY!! If necessary walk away. And if you are not sure, give it 5 more minutes, and add butter only when the meringue is cooled.
- Should I throw my buttercream - NO!! This one breaks my heart every single time. If you think it did not work - don't throw the buttercream - place it in the fridge and send me a comment below. And I may be able to help you fix it.
- My buttercream is too buttery - Yes, unlike American buttercreams, meringue buttercreams are buttery. Since it's essentially sweet whipped egg whites with butter. Light and fluffy in texture, and yet, it is buttery and it's ok if you don't like it.

Hi Veena, my meringue/butter mixture is really soupy. I whisked the egg white mixture until I got stiff peaks and the mixing bowl felt cool before I added my room temperature butter. Pretty much as soon as I added the butter the meringue just deflated. I tried sticking into the fridge and rewhipping for a long time but it’s still super runny.
What did I do wrong please? Can this still be saved?
Veena Azmanov
If it is still runny means the butter was added too soon and it is still not cold enough. Chill it well, then switch to a paddle attachment and whip it until light and fluffy. If you loose volume from the egss, you my need to add a little powdered sugar. But you will be able to use it.
JanessaNadeau
Hello I've made this twice now, and my meringue isn't whipping to stiff peaks.... I am adding the butter when it's soft peaks. then the butter melts and is chunky. I put it in the fridge and tried to re-whip... it just looks like chunky separated butter. Any hope? There's also like a white watery substance that doesn't want to mix back in. I guess it broke?
Veena Azmanov
If it is soup consistency means you added the butter too early and the meringue has melted the butter. You need to put it in the fridge for a few minutes until it is cooler and then whip it again.
The white watery substance means the egg whites have separated from the protein. You can try whipping it.
Janessa
After adding my butter it's chunky and greasy. I put in fridge to cools and whipped again and there's like white egg soup floating that won't incorporate
Veena Azmanov
If it is soup consistency means you added the butter too early and the meringue has melted the butter. You need to put it in the fridge for a few minutes until it is cooler and then whip it again.
Anne
I've done the meringue powder and sugar over a double boiler and am now whipping it in my stand mixer. It's taking ages and will not whip like a meringue. What have I done wrong???? My bowls were clean and I used the exact measurements. Please help!
Veena Azmanov
Anne, Sorry not sure. But, the most common mistake people make is. Don't clean the bowl and whisk properly. Or they don't mix it enough on the double boiler until it becomes sticky like egg whites.
I would say whip a few minutes more and see if works. Check to see if the egg white powder is good.
Anne
Thank you Veena. I think that's what happened - I didn't whip long enough in double boiler although it was 160°F. However when it didn't come to stiff peaks in the stand mixer, I still added the butter and it turned out great. Maybe a little greasy but went on the cake like a dream. I'm very happy with the results and will make sure I whip it longer next time as I'll certainly be using this method again. Thanks so much 😁😁😁🎂
Veena Azmanov
I am so happy to hear that Anne. Thank you so much for the feedback.
Anne
Can I use this buttercream under fondant or is it too soft?
Veena Azmanov
Yes, of course, Anne. You can use this buttercream under fondant
Gia
Hi, I’d like to make a marshmallow-like frosting similar to a 7 minute. Can I just follow this recipe & not add the butter, or will I have to adjust the amounts of the ingredients?
Thanks
Veena Azmanov
Gia. Without the butter, this would be a nice meringue so yes, similar to that
Danica
Hello Veena,
Love your recipes. What do you mean those who enjoy a good weather can even keep it out of the fridge for 2 days? I have a friend who woudl like a smbc but she cannot put it in the fridge due to a surprise party. I thought powdered egg whites would be safer than fresh egg whites. She would collect cake on Friday morning and eat it on Saturday evening for a small party. What's your advice?
Veena Azmanov
Danica. In warm weather, egg whites become softer even when whipped with meringue powder. You can do a test and see how it works for you. I think Friday morning up to Saturday morning might work in a cool dry place.
Danica
Hello Veena, temperature is about 20C. The cake would be filled with smbc and then covered in American buttercream and sugarpaste....I might tell her to put some ice packs around cake box, would that make it any better?
Veena Azmanov
That sounds ok to me Danica. I think that should work
