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.

Hm…domes…good for cupcakes, sorta annoying for layer cakes. 🙂
I wonder if you bumped up the baking temperature a bit, if the cupcakes would have a more dramatic rise? Obviously you’d need to reduce the baking time…but you knew that. 😉
It doesn’t look like any of the white cakes I’ve made in cupcake form have had a nicely domed top, but Dorie’s Perfect Party Cake was the most rounded. It’s a great tasting cake too.
Go-tos are ALWAYS good to find. I’m going to have to try these because I am still on the lookout for a go-to white cake. They look awesome!
These look awesome! I understand your desire for that perfect dome, though.
I’m happy to have one for chocolate cake, but I wish I had more go-tos! I think part of my problem is that I rarely repeat things. I just keep trekking down that endless “to bake” list of mine… Haha
Oh my word! You sound like me talking about “go to” recipes. That is my quest in life…well, in baking anyway. AND white cake is one that I have NOT found a “go to” recipe for and believe me, I have been searching for years. Literally. I also came across Bridgette’s blog where she did the white cake comparisons and I forget which one I chose to make, but I did not care for the results at all. Sigh. I was disappointed because I was certain that I would no longer have to search. I’m still at it. I also agree with you on the dome part. I definitely want my cupcakes to have a dome on them and if they don’t, I consider them a failure – no matter how good they taste. I’m kind of obsessed with the whole doming aspect.
Well, it looks like you have possibly found your “go to” white cake recipe. I guess I will keep searching. Your look amazing. Seriously – I feel like reaching through my computer screen and eating that cupcake that you have cut in half. Yummy!
Good post! Thanks for sharing.
These are beautiful! I also like domed cupcakes, but it never works out that way.
This recipe is my go-to for white cake, too!! I’m so happy to see someone else post about it.
I love the crumb on those!
You might try starting your cupcakes at about 25 degrees more than usual, then when they just start to doom, reduce the temp back down. This has worked for me when I have had a flat top type batter.
I have always had a similar problem so I thought i would do some searching and came upon this comment…

Here is the recipe for the buttercream
Hello. I found your site off pinterest in a continuing search for the perfect white cake. I have possibly a very strange question, and i’m hoping you can help guide me here. I’m doing a birthday cake for my husband and my daughter, and I’m making it a flag inside (red and white layers w/ a blue center circle). my husband loves red velvet, so i’m hoping to do that for the red layers, but i’m having a hard time figuring out the perfect mix of flavors to do the white layers? would this recipe mix well w/ red velvet?

I think this recipe would go great with red velvet. I love the idea of a flag cake, although I’ve never made one myself.
My first cake made from scratch and this recipe made it a success. Super happy with the results. Thank you!

So glad you enjoyed the recipe! Great job in taking on the challenge of making a cake from scratch.
Hi! I found this recipe whilst searching for one to make a purple ombre layer cake for my best friend’s birthday. However, I am from the UK and whilst having US measuring cups, I don’t really know what cake flour is? I’m sorry if this sounds ridiculous but we don’t have it over here! Can I use Plain Flour instead as the recipe includes a raising agent? And is it the cake flour that gives the cake its white colour? Please help! Kindest regards, Naomi x

The white color of the cake comes from the fact that there are no egg yolks in the recipe. I have never substituted anything for cake flour, but here is what Joy the Baker has to say about it: http://joythebaker.com/2013/12/baking-101-the-best-cake-flour-substitute/
Hi, I’m baking a bday cake for my sis and I’m attempting to make the purple ombré cake too. Will be using the white cake recipe. Just wondering
1. Can I still use the same 24 cupcakes quantity to make 3 layers of 6″ round cakes?
2. Would the cake be still moist if I bake the cake 1 day ahead?
Thank u so much!
