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. 
Unfortunately I didn’t enjoy these. It had all my favourite flavours, so I thought they would be delicious but I had a feeling whilst making they were going to be too sweet, and they were.
Also the base definitely needs increasing as half the mix barely covers the bottom of the tin and with two wet elements it needs to be sturdier. Whilst the side pieces all stayed together the middle ones were just a gooey mess.
But still didn’t detract from the biggest issue – far too sweet. (And I have plenty a sweet tooth!)
Lovely blog though! (Sorry, hate leaving negative feedback! I just wouldn’t want someone else to have the same issues. Also, tinned pumpkin is quite pricey in the UK so wouldn’t want others to waste money on a recipe that doesn’t work)

Sorry to hear this recipe didn’t work out for you… Thanks for the feedback.
I’m going to try these. I think Brits don’t generally eat things as sweet as we do and I read the recipe and it doesn’t seem as if it has too much sugar, but I am going to double the crust recipe because it does seem as if it is a bit scant, plus I’m going to make a double batch. Tell me, do these have to be stored in the fridge? I see the note to put in fridge to set. Are they too soft at room temp? If so, do you think not adding the milk to the dulce de leche would take care of that? I’m bringing them to an event and there will be no refrigeration available.
