  • In an electric mixer fitted with the whisk attachment, beat egg whites with an electric mixer on low until foamy. Add cream of tartar; beat on medium high until stiff but not dry.

  • With mixer running, pour syrup down side of bowl into egg whites in a steady stream, and beat on high speed until steam is no longer visible, about 3 minutes. Beat in butter a few pieces at a time. Add vanilla and beat until smooth. If it looks curdled at any point, keep beating to smooth out.

This is a really good recipe! You really need that candy thermometer, because the syrup needs to have the soft ball stage. If you have this, it's quite easy to get a wonderful creamy buttercream! The eggwhites don't have to be perfectly roomtemperatured, so the butter. But it's better if it's not frozen before you mix it in.

This is a perfect Italian buttercream base that serves as a jumping off point for a variety of frostings. Euro buttercreams do require correct technique. Common mistakes? Not heating the syrup to soft (or even firm) ball stage. Getting too much of the syrup on the edge of the bowl or beater. Egg whites that are too cold. Not having the butter at true room temperature.

I made this recipe today and it turned out well. I agree that a candy thermometer is key to the success of this recipe. When the temperature reached the soft-ball stage on the thermometer, I took the pot off the burner. When beating in the butter pieces, the buttercreme will be liquidy, but as you keep adding more butter, it will thicken up to a piping consistency. My stand mixer is currently broken, so I used my electric beaters instead. I took longer but worked like a charm.

I made this recipe. You should use confectioners sugar if you are gonna do it. So what you would do is whip your egg whites until they have a medium peak, add cream of tartar, then add a little bit of butter at a time and also add confectioners sugar until it tastes just right. I am always up for trying new recipes but I didnt like this one. I work in a bakery full time making cakes and decorating them. I have a hard time with online recipes though.

I stumbled across this recipe and took a chance, considering this is my first time ever making an Italian meringue buttercream. I started to panic once I added the butter, I wasn't sure if it was melting, but with some vigorous beating with my KitchenAid mixer, it soon became light and fluffy - it held its shape perfectly! I would also highly recommend a candy thermometer.

It was the first time I have made an Italian Buttercream (and I used a hand mixer!) and it turned out perfect. Luscious and divine! Here are my thoughts: 1. A candy thermometer is a must! 2. Yes, it turns soupy; just keep beating it (about 5 minutes). Put it in the fridge for 10 - 15 minutes and beat again – this helps the cooling process. 3. Have no fear – I’m fairly convinced soufflés and Meringue Frostings can sense fear. If it fails, go to the bakery, and try again another day.

THE perfect buttercream recipe. I have converted many American Buttercream lovers with this one. Pure buttery taste, smooth and not too sweet! Takes color, pipes and holds it shape very well. DO NOT panic when the recipe "breaks", it will come back together.

I've made this recipe a bunch of times. You have to get the sugar to the right temp, though, that's absolutely critical. If you don't have a thermometer don't use this recipe. period. I have gotten to the point where I can eyeball it (the water boils off, & once the bubbles get big, its close.. like 10 min), but your best bet would be to put the sugar & egg whites in a double boiler, stir until the sugar is dissolved & its really runny (~5min), then whip to stiff peaks. Then add the butter.

I don't why, but every Martha recipe I have ever tried is missing something and is a disaster , you have to figure it out and it could be very costly, but that's how she keeps her secret.. very disappointing....so it's not you it's her recipes...

Mine was also a failure and I used a candy thermometer. It's a runny mess. I tried heating it in a double boiler and beating it to salvage it - that didn't work. Any suggestions?

carrieknific, you really do need a thermometer for this icing, think of it as a required ingredient. "Soft-ball stage" is the temperature at which your syrup will form a soft-ball when a spoonful is dropped into a glass of cool water. It is also important to note that when making syrup after it has reached a boil you should not stir. If you aren't interested in making a syrup but still having a soft buttery frosting try making Martha's Swiss Meringue Buttercream instead. It's just as delicious.

Regarding Step 1, I had no idea what "soft-ball stage" meant, and I do not have a candy themometer. I cooked the sugar and the water for what I thought was appropriate -- I did not want the sugar to burn-- and low and behold, my frosting was a failure. Did I boil it too long? Not enough? Did I take too long, causing my stiffened egg whites to droop? It was all too watery. Luckily, I had time to refrigerate the frosting overnight, so I was manageable but not the pretty, light fluffy I wante

cupcakechick1964 if you keep beating the curdled mess will come back together into this amazing smooth silky Italian Buttercream. It doesn't always "break" but in my experience the best results is when it does!

I tried to make this and it was a complete failure! I followed the recipe but once the butter was added, it lost its volume and ended up a runny mess! Any Ideas as to what could have gone wrong?
