My Favorite Swiss Meringue Buttercream Frosting Recipe
Swiss meringue buttercream is like heaven. It’s so light and fluffy and not at all overly sweet like some frosting. I definitely prefer it over any other kind of frosting.
Ever since I first tasted SMBC I have been searching for a fool proof recipe that I love. I have found that recipe. Trust me on this one. It’s amazing.
Most people seem intimidated by SMBC because of the fact that sometimes it curdles when you’re mixing it up. You have to be patient and know that it’ll come back together. Because of the technique used in this recipe, you won’t have to worry about that here. I was a bit skeptical when I first tried this recipe, but it works every time.
I prefer to refrigerate my cupcakes after frosting them with this SMBC. This will set the frosting. Then bring them to room temperature prior to serving.

Swiss Meringue Buttercream
This is my favorite Swiss meringue buttercream
Yield: Enough to frost 24 cupcakes
Ingredients:
4 oz egg whites (3-4 large egg whites or about 1/2 cups)
1 cup granulated sugar
1 lb unsalted butter, room temperature
2 tsp lemon extract, almond extract, orange extract, or vanilla extract
Directions:
Lightly whisk egg whites and sugar together over simmering water until egg-white mixture is hot to touch or a candy thermometer reads 140°F (60°C).
Pour hot whites into a room-temperature bowl and whip with a wire whip until double in volume on MEDIUM-HIGH speed. When the mixer stops, the meringue should not move around in the bowl. Meanwhile cut up butter into 2-inch pieces. (The butter should be slightly moist on the outside but cold inside.)
On your mixer, remove the whip and attach the paddle. Add half the butter into the bowl immediately and pulsate the mixer several times until the meringue has covered the butter completely. To pulsate the mixer, turn it on and off in a jerky motion. This forces the butter on the top to the bottom of the bowl. Add the balance of the butter and pulsate mixer several times. Slowly increase the mixer's speed, starting with the lowest speed and increase the speed every 10 seconds until you reach a MEDIUM-HIGH speed.
Continue beating until the mixture begins to look light and fluffy. Stop the mixer and scrape the bowl. Reduce speed to LOW. Add flavoring and continue to beat on LOW speed for 45 seconds. Then beat on MEDIUM-HIGH speed for an additional 45 to 60 seconds.
Leftover buttercream can be placed in plastic containers with lids and kept in the freezer for up to 3 months. Defrost completely (several hours) and rewhip before using.
Storage: Store the icing in an airtight container and freeze for up to 3 months.

I am Jen the Beantown Baker. Engineer by day and baking maven by night. Hubby serves as my #1 fan and official taste tester. We got hitched back in 2006. Barefoot. In the sand. With the waves crashing behind us. It was one of the best decisions we’ve ever made. 
Raspberries are my very favorite food on the planet and this looks absolutely divine. Thanks for sharing this!
Its my husband birthday on Fri I might try to talk him into having this cake for it.
awesome work, Jen! It sounds delicious and looks gorgeous. I’m totally jealous of your border-piping skills too.
Beautiful cake! This is very similar to our wedding cake, I may just have to try it!
It looks beautiful and sounds delicious. I’ll have to try this one!
This looks absolutely terrific! Great job on the assembly and decoration!
really beautiful cake! and raspberries are one of my favorite fruits ever! i love the little sacs together with the crunchy seeds. hee.
Holy beautiful! this cake is quite elegant and delicious looking! I love raspberries with cake.
Jen this cake is so so beautiful! It reminds me of the triple berry cake from Sweet Lady Jane here in LA. If an opportunity every arises for me to make a layer cake (I have the same problem – it’s hard to find people to help finish it!) I will definitely try this one.
You did a beautiful job with the piping. Gorgeous.
We should be best friends hahaha. We have the same go-to white cake recipe, and we both made layered cakes this weekend! Your cake is BEAUTIFUL! You have every right to brag. You did an excellent job on the piping and decorating. It looks professional!
I added lemon extract to my strawberry frosting on my strawberry cake (which came from Bridget’s recipe), and I could taste hints of lemon. I think the extract and some lemon zest would work well.
I must make this cake!! I am 100% certain that I would like it because we have similar tastes.
Now I need to look at your overdose cake to compare it to my overload cake.
Lemon and raspberries sounds like a perfect flavor combo. Your cake looks beautiful!
OH wow, I started drooling as soon as I saw the pic. SO pretty and looks delish! Will def. have to try this one… 🙂 Thanks for sharing!
This is so, so pretty! And obviously looks delicious too. Raspberries are one of my favorite parts of spring!
Sues
I don’t think you’re bragging! I would be proud of a beautiful cake like this one.
Looks delicous!

This cake looks awesome and my mouth is watering looking at the picture right now.
beautiful cake!
This cake is SO, SOOO beautiful! I love it!!!
Looks beautiful, I love layer cakes!
you say something about videos from youtube? can you share the the links?
vertigoxcured – I updated the post with links to the youtube videos. Sorry about that.
I made this for Mother’s Day and it was a huge hit! Thanks for sharing. I added the juice of the zested lemon and an extra cup of confectioners’ sugar to the buttercream and managed to get a nice lemony tang.
I cant believe this is your first frosting coated cake. So beautifully done. And also note…that 4 layers with fruit filling without cake sliding all over the place is not a normal for first timers in that department. Kudos… you got the cake decorating skills Ma’am.
am making this cake right now, and i must ask about the proportions of flour to liquid. it seems off. i made the recipe exactly as written and it was a pool of liquid. i had a similar recipe for a white cake which called for 2-3/4 flour and only 4 egg whites + 1 whole egg ( similar), so i added another 1/2 cup flour and it was still liquidy. it took 30 mins. to bake, not 23-25. will see how it turns out. the only good part is rubbing the grated lemon zest with the sugar, although i could not taste much lemon in the batter. by the looks of the layers, i would recommend 8″ pans as the layers are quite thin. all in all a big disappointment. glad i planned ahead and will make a different recipe.

Sorry to hear this recipe didn’t work out for you. This batter was very thin going in to the oven.
Does this cake keep well? i just made three 6″ cakes, which I’ll freeze in preparation for making a little layer cake on Sunday (a top-tier wedding cake replacement for our one year anniversary, after Hurricane Sandy ruined the real one.) But I also made two dozen cupcakes with the batter. I’m planning to bring one dozen to a dinner party tomorrow and the next dozen to a party on Wednesday. Any tips for the cupcakes? Should I freeze them, or just leave them out til I’m ready to frost? Would appreciate any suggestions! Thanks.

I haven’t made this cake into cupcakes before. But in general, cupcakes are fine for a couple days. If it’s more than 2-3 days, I’d go ahead and freeze them, then frost them the day before you want to serve them.
Would it be advantageous to whip the egg whites first, and fold them into the batter at the end? It might help with the thin batter issue, and I have some recipes for white cake that call for whites whipped into soft peaks. I am making this cake for a baby shower this weekend, so I will let you know how this technique works, unless the author has an opinion against.

I have made this cake, or a variation of the cake, multiple times as it is written without any issues. I know some cake recipes do have the cake whites whipped and folded in at the end. If you try it, please let me know how it goes.
If you could email me with a few pointers on how you made your blog site look this cool, I would be thankful!
Going to endeavor to make this for my husband’s birthday next weekend. I haven’t made a cake in ages, but I like challenges!!! Hopefully it will go well as his parents are coming into town for his birthday (yikes!) I hope it has a nice lemon flavor because he loves lemon. Wish me luck!!!

I hope he enjoys it. The cake definitely has a lemon flavor. If you wanted to go super lemony, you could use lemon curd instead of raspberry curd for the filling!
Cake looks beautiful. However, each cake was an only an inch thick so was confused how to possibly cut it in half to make four layers. So after everything was cleaned up, I had to make a second round of this. The puree was tasty and plenty of it. The Frosting was delicious and plenty also. The cake itself tasted good with hint of lemon, but did not rise much at all and it had a very rubbery texture and very dense. I agree the batter was thin when I poured in pans, but it was not fluffy and light by any means after it was baked. I appreciated making it, but not a fav for me.
I know this is an old post, but I had to comment after making it for the first time yesterday. This is a lovely cake! The only downside, for me, was that the lemon flavor was lighter than I thought it would be. I ended up topping it with some toasted almonds and fresh raspberries, and serving it with homemade coconut ice cream.
*Note: My layers came out quite thin. They were both only a little over an inch thick, and the batter itself was a slightly thick/fluffy consistency. That being said, I was able to torte them without difficulty and the finished cake came out to a little over 3 inches.
