Swiss Meringue Buttercream Frosting

I wanted to try a new frosting. One that I had heard was challenging and delicious. I’ve seen many bloggers make Swiss Meringue so I figured I’d give it a try.

I tried twice and almost cried!

This frosting was finicky.

I used a recipe from “The Joy of Cooking” and it took me nearly an hour! Seriously! After 45 minutes I just couldn’t walk away from it to go pick up my daughter from school. I had to get through this frosting. I thought I had, so I put it into the fridge as I ran out the door. When I got back home I let it sit out for an hour and then went to re-beat it… and it totally separated… 🙁  The egg whites turned to liquid and I had a gross butter lump that would not smooth out. I was so bummed.

I was also out 4 egg whites and 3 sticks of butter. All of it went down the drain.

So I then googled it to search for some help from some blog friends and I came across this post from Sweetapolita. So I remade my Swiss Meringue Buttercream and watched my frosting turn into a curdled mess! I was beyond bummed – I was devastated. I was out of butter and had 8 egg yolks in the freezer.  But, she said to just keep beating and beating and I did! For like 20 minutes and it still didn’t turn into frosting.

So I searched some more and found Cath’s Cookery Creations. So I followed her advice to melt some of it and beat in the melted goo. And you know what?? It totally worked!

Happy! Happy! Joy! Joy!

Prep Time 5 minutes
Cook Time 20 minutes
Total Time 25 minutes


  • 4 egg whites
  • 3/4 cup sugar
  • 2 tablespoons water
  • 1/4 teaspoon cream of tartar
  • 1 teaspoon strawberry extract
  • 3 sticks butter
  • pink food gel


    1. Combine egg, sugar, water, and cream of tartar into your mixing bowl (from your stand up mixer). Place the mixing bowl into a wide saucepan of simmering water. The water should come up as high as the ingredients inside the bowl. Attach a candy thermometer to the mixing bowl and beat with a hand held beater until the mixture reaches 160 deg F. Remove the mixing bowl from the water, add in the extract, and return the mixing bowl to the stand up mixer.
    2. Whip with the whisk attachment until the meringue is no longer hot and the mixing bowl is at room temperature.
    3. Change out the whisk for the paddle attachment and slowly add in one tablespoon of butter at a time. The meringue will deflate and hopefully the butter will cream.
    4. If the frosting turns into a curdled mess, melt a cup of the “frosting” in the microwave and then beat back in. Add in one drop of food coloring (if desired) until color is achieved. Remember that the colors darken over time.
    5. The frosting should be smooth and fluffy.
