Directions

Instructions Checklist
  • Place whites and sugar in a heatproof mixer bowl set over a pot of simmering water. Whisk until sugar dissolves and mixture registers 160 degrees on a candy thermometer.

    Advertisement
  • Remove from heat, and attach bowl to a mixer. Whisk on medium speed for 5 minutes. Increase speed to medium-high, and whisk until stiff, glossy peaks form, about 6 minutes. Reduce speed to medium, and add butter, 1 piece at a time, whisking well after each addition.

  • Switch to a paddle attachment. With mixer on low, add strawberry puree, and beat until smooth, 3 to 5 minutes. Use immediately, or cover, and refrigerate.

Cook's Notes

Refrigerate for up to 3 days. Bring to room temperature, and beat on low speed until smooth before using.

This recipe does not work. There is no confectioners sugar so it does turn into frosting. What you are left with is a strawberry soup!

Don't waste your time making this frosting, unless you want to fail because I couldn't agree more with MS106564. I can't tell you how much time and money I wasted making this frosting and I'm an experienced baker. After dumping three batches of 'soup', I went onto YouTube and watched someone make this frosting. That was two years ago and it has never failed to come out perfectly.

Great recipe...if you want to make $20.00 strawberry soup. I splurged on high quality butter and strawberries only to watch the frosting break soon as I added the purée. Too expensive to not work out.

I haven’t tried out this recipe yet but i do have a question; how many cupcakes does this frost (piping, usual swirl)

Worked out terrifically into a light, fluffy, and firm buttercream frosting. It was actually my first time making a frosting like this and I was quite impressed with both myself and the rescipe. I had a mild freak out once I was done adding the butter as it was starting to separate. So, I quickly popped it in the fridge to cool down a bit as I prepared the purée, took it out a couple minutes later and followed a couple tips from other websites to continue wishing at a higher speed. And like magic it all came together and I continued to add the purée. For all those saying it was too runny, have patience and look up some tips on saving it before throwing it away.

This is a classic Swiss buttercream recipe. Those who it did not work for, did not follow instructions. Do not let their reviews stop you from trying this. The result was light, yet rich. Way better than a powdered sugar-based frosting. I did hold back a bit on the strawberry puree and used 1.25 cups. I was able to pipe it into a loose, thick swirl, though I could've let it cool and harden in the fridge a bit (but I impatient). I would make this again.

Does anyone know if this recipe is suitable for piping rosettes onto a layer cake? I experimented this week with another strawberry buttercream, and the fruit made it unstable. They wouldn't hold their shape.

I'm BEYOND DISAPPOINTED! I purchased your book and this recipe if just a disaster. After adding the puree my buttercream curdled and just became a nasty thick soup. After reading the reviews I noticed I wasn't the only one, and this really makes me mad! Now I have to search your recipes ONLINE from your book just to see if they're worth trying out. I also kept beating the buttercream for about 20 mins more and it was still a disappointment, second time throwing it out. Waste of time and money :(

This is the BEST frosting. A stand mixer works best, the butter should be cool, not warm and add it in 2-3 tablespoon blobs. Mix for several minutes after adding all the butter. Keep the strawberry puree cold and be sure to switch to the paddle when adding it. And it is true that after adding the strawberry puree it looks like a mess, but don't give up. Let the mixer run and it will come together beautifully.

Someone who had great success with this, please tell me what is meant by 1 1/2 cups strawberries pureed? a) is that 1 1/2 cups of strawberries or 1 1/2 cups of puree? b) how do you puree it?

Mine also broke, however having made buttercream before I know that you just need to continue beating it & it will come back together. I turned up the speed & beat for a few minutes, it came back together & turned out delicious. Also I made it with puréed & strained blueberries.

This buttercream is perfect, resilient, and tasty IF you follow these few tips. 1. fresh berries only, when they are frozen the extra h2o will break it, look up phase separation. 2. use a spatula to mix in the puree beating it could over whip everything you worked to create, nice and easy. it will look horrifyingly irreversibly thin and chunky, keep going just nice and easy, itll smooth out. do ahead: to revive it, put the entire batch in to a low double boil to bring back to rm temp & see #2.

VERY DISAPPOINTED !!!!!!!!!!! I followed the recipe exactly as listed, once I added the puree the whole thing fell apart. All that work with disappointment. I really think that this recipe needs to be redone so this problem doesn't happened to future makers.

I didn't use a thermometer with the egg whites & sugar, I just sort of eyeballed it and made sure the sugar was dissolved. The recipe was beautiful up until adding the puree, like everyone else. I used frozen whole strawberries since they weren't in season & my puree was a bit runny, so I added only 1 cup. It thinned the frosting out a bit & I beat for 10 minutes - still a bit thin. I put in a sealed container over night & it thickened right up & although not still quite as thick as I'd like.

This is delicious frosting!! I added 1.5 cups of pureed strawberries (actually I added even more than that), not 1.5 cups of strawberries that were pureed. It did start to separate but all I needed to do was turn up the speed on the mixer and pour the puree in slowly and it all came together. The puree was cold too, and it worked fine. You just need to add the puree very slowly or else it will separate just like a salad dressing.

Yummy! I would actually prefer it to be a tiny bit sweeter, but love that it is not sickening sweet. If you are having trouble with separation at the end, keep beating and add a few more tablespoons of softened butter. It should come back together.

PERFECTION!! Adding Strawberries: Cut strawberries into halves THEN measure out 1.5cups. Also make sure your berries are dry before you puree, you do not want extra water in the recipe. Do not add puree all at once…small doses… I actually ONLY used 80% of the puree in my buttercream and it tasted great. Making Swiss Meringue is time consuming… it takes about 5-7 mins to cook on stove top and about 10 mins to come to stiff peak .. Hope this helps!

I just made this and it turned out great. I followed the recipe but I didn't use a candy thermometer, I just let the sugar dissolve and whipped it really well. I used my mixer and mixed exactly as long as it said to. One thing I was confused about was the strawberries. I wasn't sure if it called for 1 1/2 cups of strawberries and then puree them, or 1 1/2 cups of strawberry puree. I added the puree very slowly and used about 3/4 cup of puree. I was afraid it would be runny if I used more.

@ChristinaStallard Thanks for the tip! I have made this recipe countless times because of the taste (not sweet as the usual buttercream) and I have only had the perfect consistency ONCE out of all those times!!! I don't understand how the butter can still be too cold... maybe because the eggwhites came from being hot? My prob starts after adding the puree, it doesn't mix into the buttercream smoothly and stays liquid. So if I gently heat it all up over simmering water it'll come together then?

I needed a Valentines Day cupcake frosting, this pink strawberry topping looked adorable! I used my kitchen aid blender and a good digital thermometer to keep with with instructions. I usually prefer a whipped cream frosting but this frosting is pretty and has natural ingredients. I left my cupcakes out of fridge in a container overnight,and put frosting in fridge since it has butter and eggs. Had to microwave to soften frosting for fast spreading next day.

This recipe can be tricky when the puree is added because it can cause the frosting to separate. Make sure the puree and the butter are at room temperature. If your frosting does separate and becomes greasy and lumpy, place it over a pot of simmer water and beat until it regains the proper texture. Swiss meringue buttercream tends to separate if the butter is too cold when added to the mixture. You might consider using less butter as well. Mine worked after some trial and error. Good luck!

Yeah, the same separation happened to me. Beautiful buttercream then added the puree and it went to a disgusting, though still tasty, mess. I've been mixing it on low with a paddle for the last half hour and it's barely starting to mix... too much work for me. Hopefully it'll eventually take otherwise I'm hooped and have nothing to frost my cupcakes with.

Can someone help me figure out what I'm doing wrong? I tried this recipe twice, and both times it was a complete flop. First time I didn't use a candy thermometer, second time I did. First time, just before I added the strawberry puree, the frosting 'split', and the second time it happened when I added the strawberry puree. It ended up being a blobby mess. Ahhh!!! What a waste. What did I do wrong?!?

This icing was amazing. I made it with the Sprinkles Strawberry Cupcakes recipe: http://www.marthastewart.com/258957/sprinkles-strawberry-cupcakes. They were a huge hit! I was worried that the icing wouldn't turn out because my digital thermometer stopped working during the first step. Then when I added the strawberries it looked like strawberry soup. I turned away from the mixer to look for powdered sugar to add to stiffen it up, and when I looked back it had firmed up into perfect icing!

SMBC, will you EVER be fully tamed? It seems that the Swiss Meringue buttercream base of this frosting only works for me about 60 percent of the time. Today, the failure was at the egg white stage; no matter how long I whipped, they just would not fluff. *hangs head in shame*

i got it! for the frosting, after you add in the puree you're gonna see some "phase separation", which seem like the butter is separating into small chunks away from the liquid. just keep beating the mixture for at least 5 minutes and everything will come back together into normal frosting look.

Chagen, you either added your butter before the egg whites and sugar had cooled down completely, your butter wasn't soft enough (it should be squishy) or you added the butter too fast and it didn't have enough time to combine with the egg white mix so the entire thing broke or "chunked up." Wait until the bottom of your mixing bowl is cool before you add the butter and add it slowly only a few pieces at a time checking to make sure that the butter and egg mix combines before adding more butter.

would using confectioners type sugar be better? There is a good recipe for buttercream frosting on the bag and I am going to try it. I think it's the moisture content of the strawberries that ruin the frosting so how about just a buttercream with a drop of red food color? The cupcake will carry the fresh strawberry taste adequately I feel.

my frosting separated too, but I didn't wait for it to fully come to room temp, so that probably has something to do with it. Best just to use all at once, I think.

Yes I had a problem with the strawberries, I had to throw away my entire batch, because I didnt drain the strawberries after I pureed them...so upsetting. When brought back to room temp the buttercream looked very unappetizing.

Buttercream was rather flavorless except for strawberry touch. Rather greasy texture but pairs well with yellow cupcakes. After pureeing the strawberries, I put them in a colander over a measuring cup and let the excess water drain out. Had read previous reviews that adding strawberries made it watery. This seemed to do the trick.
