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.

They look soooo good! Thanks for the tip about the sweetness factor…I love having a little bite of something completely decadent!

I’m not sure it is possible to be “too sweet” but these look very good!
These looks so good! Can’t wait to try!
I’m not crazy about marshmallows, but these brownies look amazing!!
“nice and thick”… wow, you aren’t kidding. that was a bold move switching the pan though. glad it worked out in the end.
MMMMMMM those sound awesome!!
oh my word! those look delicious!

These look AMAZING! I feel like I need to go to the gym just looking at them. 🙂
These look delicious! I love anything with marshmallows!
I wish I could reach through the computer and grab these! They look awesome!!
I make something similar but cheat and use a boxed brownie mix. The frosting I use doesn’t have marshmallows in it which helps with the sweet factor.
That’s a great idea baking these in a smaller pan. I would prefer the brownie part a bit thicker.

Um…I guess I didn’t let my icing cool enough and it melted the marshmallow completely…it looked like Mt. Vesuvius erupted on my counter ha ha! I wish I could post a picture! They still tasted yummy though =)
I made these, but the chocolate topping turned out not great, not dissolved and gritty. – I think you mean “icing sugar” don’t you, when you say sugar for the frosting?

I used granulated sugar for the frosting. When it is cooking on the stove, it should completely dissolve the sugar.
