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.

Your costumes are so cute!
I love the fondant too. I’m going to be trying fondant for the first time next weekend. You make it look so simple!
I MUST try this! I’ve been avoiding fondant cause of all the terrible things I’ve heard about the taste. Problem solved – thanks! You guys are so creative with the costumes too.
That is so awesome. An annual pirate party? Sounds like a blast. I love your shirts too. If my kids weren’t already set on their Halloween costumes, I’d suggest being a treasure map instead. That is so creative!!!
Oops – forgot to mention the cupcakes. : )
Very cool. I’ve never made fondant because I’m afraid it tastes bad. Is it good?
It is good! It tastes like marshmallow but sweeter.
Delicious! If that was your first time making fondant I would give yourself a big pat on the back:) It looks awesome! I need some mad cupcake skills like yours!
After my current box of fondant has run out I am so making some marshmallow fondant – and now that I know you can use the KitchenAid even better!
Wow, you did an amazing job! Thank you for the fondant tutorial, I’ve never made fondant before… you make it look so easy!
