Swiss Meringue Buttercream

Ingredients

Ingredients

  • 5 large egg whites
  • 1 cup plus 2 tablespoons sugar
  • Pinch of salt
  • 1 pound (4 sticks) unsalted butter, cut into tablespoons, room temperature
  • 1 1/2 teaspoons pure vanilla extract

Directions

Combine egg whites, sugar, and salt in the heatproof bowl of a standing mixer set over a pan of simmering water. Whisk constantly by hand until mixture is warm to the touch and sugar has dissolved (the mixture should feel completely smooth when rubbed between your fingertips).

Attach the bowl to the mixer fitted with the whisk attachment. Starting on low and gradually increasing to medium-high speed, whisk until stiff (but not dry) peaks form. Continue mixing until the mixture is fluffy and glossy, and completely cool (test by touching the bottom of the bowl), about 10 minutes.

With mixer on medium-low speed, add the butter a few tablespoons at a time, mixing well after each addition. Once all butter has been added, whisk in vanilla. Switch to the paddle attachment, and continue beating on low speed until all air bubbles are eliminated, about 2 minutes. Scrape down sides of bowl with a flexible spatula, and continue beating until the frosting is completely smooth. Keep buttercream at room temperature if using the same day. If not, transfer to an airtight container and refrigerate up to 3 days or freeze up to 1 month. Before using, bring to room temperature and beat with paddle attachment on low speed until smooth again, about 5 minutes.

To tint buttercream, reserve some for toning down the color, if necessary. Add gel-paste food color, a drop at a time (or use the toothpick or skewer to add food color a dab at a time) to the remaining buttercream. You can use a single shade of food color or experiment by mixing two or more. Blend after each addition with the mixer (use a paddle attachment) or a flexible spatula, until desired shade is achieved. Avoid adding too much food color too soon, as the hue will intensify with continued stirring; if necessary, you can tone down the shade by mixing in some reserved untinted buttercream.

                This worked amazing for me! Wanted to test it because of all the mixed reviews. I was looking for something less rich than traditional buttercream and I found it!! Would recommend!

                This is absolutely amazing. This is the best buttercream that I have ever made. I had to double the recipe to make my 2 layer ombre cake, but if you weren't doing the extra ombre layer, I think that you wouldn't need to double it. This buttercream is so light and fluffy, and not too sweet. It is also super easy to make. I will be recommending this recipe to everyone I know.

                The ratio of eggs to butter is out by a long way. I fixed what I’d made by whipping up an extra 4 eggs and just under a cup of sugar. Disappointed. Helenjzk

                Very smooth and creamy, and not too sweet- a huge hit. The texture was fantastic, and it piped beautifully. It's definitely less sweet than an American buttercream, but everyone (kids and adults alike) at my party loved it.

                Delicious... satin smooth... perfect amount of sweet. Received rave reviews. Easy to make, that seems to be foolproof. Absolutely a go to recipe! 
                Cupcakes Note: I stumbled across a SMBC recipe for cupcakes after I made this one (for cupcakes) so I will make that one next time. The ingredients are the same, just increased here and there. So, just FYI in case you are making cupcakes, there is another recipe out there by Martha. 
                It is not white-white because of the butter, obviously.

                This is the first recipe of Martha's that has let me down. I followed the directions exactly and texture-wise, it looks fantastic, but it tastes as if the cake is frosted with pure butter; it has zero sweetness and feels like nothing but butterfat. Guess I will stick with my regular American buttercream.

                I have always been afraid of making a meringue buttercream. Until now. I used very good ingredients, and followed the recipe/instructions to the letter. I was rewarded with a beautiful, not too sweet, spreadable, and easy to pipe frostin. As with every other recipe from Martha, it came out perfect! This is now my "go to" buttercream!

                Metric conversion charts are provided in many cookbooks. Conversion calculators are also available on line. Some basic information: 
                1 stick of butter = 8 tablespoons = 1/2 cup
                1 cup = 240 mL = 8 fl. oz.
                1/2 cup = 120 mL = 4 fl. oz.

                I've used this recipe many, many times.  In order to be successful, you MUST beat the egg white/sugar mixture until it is TOTALLY cool, or the butter may melt as you add it.  If that happens, you are doomed to an irretrievable mess.  The other possibility that may cause the buttercream to separate is if your kitchen is too hot.  Otherwise, it's beautiful and tasty!  Don't give up - the end result is totally worth the extra time!

                Great recipe.  I use about a third less sugar because I found it was still too sweet; I also add about 8 oz of whipping cream towards the end to lighten it up.  If you run into a problem - DONT throw it out!  If its too runny, refrigerate for 15 min.  If it gets too cold (like when I add the whipping cream) - it will separate into solid curds.  Just take about a third of mixture and warm it up (microwave, or I prefer double boiler) then add it back and continue beating.  It really does work!

                I love this frosting, made it last month for the first time for my youngest Granddaughters birthday cake.  Making it again tonight for my oldest Granddaughters cake but it  doesn't seem to make 5 cups either time.  I wonder if I'm doing something wrong.  I'll keep making it but maybe in double batches, I think my family would kill me if I made anything else...

                This is a great swiss buttercream recipe! It yields a very creamy, soft and not overly-sweetened buttercream with a great texture. I tried the chocolate variation too and it is very good as well, although the product's final colour is brighter than what i have anticipated. If you are looking for a dark-brown chocolate colour I'd recommend adding more chocolate or altarnatively adding some cocoa powder to it. 
                In summary, wonderful!

                Best Swiss Meringue buttercream ever!  If yours starts to look sloppy, wet and separated, crank up the mixer and let it beat for 5-10 mins.  It will come back together after more mixing. It is fabulous!

                I just made this and I have to say it was just horrible! I followed the instructions exactly and it amounted to nothing more than a sloppy wet mess! No consistency, no texture, no peaks, just a liquid mess! Complete waste of eggs, butter and sugar! I will not be using this "frosting" recipe ever again!! Terribly disappointed!

                I love this recipe and it's worked out beautifully every time. I want to try it with the chocolate but am unclear about where in step 3 to fold in the chocolate? Do I fold it in and then beat with the paddle attachment or wait until after the buttercream has been completely beaten with the paddle and then fold in the chocolate?

                This recipe is awesome! I made 2 batches for a party and it came out perfectly. Everyone kept commenting on the frosting. Very silky and stable. We accidentally left one of the cakes out overnight after the party and it was still perfect. I followed the directions exactly. You do need to make sure the bowl has cooled down. The first time I made it, I think it was a little too warm. So the second time I wiped the outside of the bowl with cold wash cloth.

                Cook the egg whites & sugar until it registers 120 degrees in an instant read thermometer. Then immediately whip in mixter on high speed with whisk attachment until it cools to 80 degrees...takes about 7 mins. Then start adding the butter. I haven't had this fail yet.

                I'm not sure what I do wrong, but my buttercream becomes runny, like liquid. Maybe I don't let the egg and sugar cool down enough before I add butter? It's happened to me twice. I will continue to try, because the taste is wonderful!

                I am a professional pastry chef and this has become one of my 'go to' buttercreams., I have used this recipe several times and have never had any problems with it the day after.  Let it come to room temperature and beat on low speed with paddle attachment.

                I absolutely love this frosting, as it's light and sweet without being overwhelmingly buttery.  To make a mint variation, I omit the vanilla extract and use 1T peppermint extract.
                
                My only tip though is to NEVER try to refrigerate it for use the following day.  The liquid and solids completely separated and I just could not for the life of me beat it back into a normal consistency.

                sounds like your meringue was too hot or over beaten, maybe.  that would be my guess. Be sure too, to have a very very clean bowl.

I'll keep making it but maybe in double batches, I think my family would kill me if I made anything else...

                I have been making this frosting for years, and it never disappoints. It is incredibly smooth, and not overly sweet. Love it!

                This recipe worked perfectly for me, although the whites took upwards of 20 minutes to whip with a hand mixer.

                This is a great swiss buttercream recipe! It yields a very creamy, soft and not overly-sweetened buttercream with a great texture. I tried the chocolate variation too and it is very good as well, although the product's final colour is brighter than what i have anticipated. If you are looking for a dark-brown chocolate colour I'd recommend adding more chocolate or altarnatively adding some cocoa powder to it. 
                In summary, wonderful!

                Best Swiss Meringue buttercream ever!  If yours starts to look sloppy, wet and separated, crank up the mixer and let it beat for 5-10 mins.  It will come back together after more mixing. It is fabulous!

                I just made this and I have to say it was just horrible! I followed the instructions exactly and it amounted to nothing more than a sloppy wet mess! No consistency, no texture, no peaks, just a liquid mess! Complete waste of eggs, butter and sugar! I will not be using this "frosting" recipe ever again!! Terribly disappointed!

                I love this recipe and it's worked out beautifully every time. I want to try it with the chocolate but am unclear about where in step 3 to fold in the chocolate? Do I fold it in and then beat with the paddle attachment or wait until after the buttercream has been completely beaten with the paddle and then fold in the chocolate?

                This recipe is awesome! I made 2 batches for a party and it came out perfectly. Everyone kept commenting on the frosting. Very silky and stable. We accidentally left one of the cakes out overnight after the party and it was still perfect. I followed the directions exactly. You do need to make sure the bowl has cooled down. The first time I made it, I think it was a little too warm. So the second time I wiped the outside of the bowl with cold wash cloth.

                Cook the egg whites & sugar until it registers 120 degrees in an instant read thermometer. Then immediately whip in mixter on high speed with whisk attachment until it cools to 80 degrees...takes about 7 mins. Then start adding the butter. I haven't had this fail yet.

                I'm not sure what I do wrong, but my buttercream becomes runny, like liquid. Maybe I don't let the egg and sugar cool down enough before I add butter? It's happened to me twice. I will continue to try, because the taste is wonderful!

                I am a professional pastry chef and this has become one of my 'go to' buttercreams., I have used this recipe several times and have never had any problems with it the day after.  Let it come to room temperature and beat on low speed with paddle attachment.

                I absolutely love this frosting, as it's light and sweet without being overwhelmingly buttery.  To make a mint variation, I omit the vanilla extract and use 1T peppermint extract.
                
                My only tip though is to NEVER try to refrigerate it for use the following day.  The liquid and solids completely separated and I just could not for the life of me beat it back into a normal consistency.

                This is my go to recipe for cakes.  I love it and after making several batches for a wedding cake, it became so easy to do, I can't live without it.

                sounds like your meringue was too hot or over beaten, maybe.  that would be my guess. Be sure too, to have a very very clean bowl.
