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’ve been anxious to try rhubarb but after many trips to the grocery store missed the season. (it sold out-FAST!) Did you use fresh or frozen rhubarb? I just saw the frozen kind and have been thinking about giving it a try.

Ingrid – I made this when I was home in the Midwest back in June. It seems easier to find out there than in the East Coast where I live. We use fresh and I’ve never used frozen although my dad does freeze his for the rhubarb rolls I made a few weeks ago too. I should have grabbed a ton and froze it myself…
I made these for a 4th of July party. we ran out of fresh and had to use frozen rhubarb, which tasted fine, we couldnt tell the difference (but we also had the fresh mixed in). Although I would suggest cutting the frozen pieces up a bit more- they came out of the bag huge! ~Jen’s older-younger sister
thanks little sis! Were they store bought or did Dad freeze them from fresh?
No kidding – those look like the best dessert ever!! I’m starring and making for sure!
Ya know what- I’ve never made anything with rhubarb! But those sure look yummy so I might have to try it 🙂
These look delicious!
I love rhubarb, what a great new way to use it;)
I really need to try rhubarb. I am afraid I won’t like it, but this looks like a great recipe!
Thank for the info Jen! I just may go ahead and give frozen a try otherwise its wait a year.
