If you’ve never had this old-fashioned 7-minute frosting, I’d like to apologize. I am so sorry that you’ve missed out all these years, seeing as it’s been around since the early 1900s. This is a fluffy, glossy, and light-tasting icing reminiscent of meringue… only better and spreadable. It’s commonly found atop coconut cakes or other holiday cake treasures but goes just as easily with a simple pound cake or chocolate cake too.

There are many reasons to love this recipe, but most importantly it’s quick to make, easy to spread, and doesn’t include a double boiler like so many others. Unlike most 7-minute frosting recipes, this one is also not dependent on the weather or you crossing your pinky toes and perfectly reciting the magic word with five extra-large marshmallows in your mouth. No siree, this one comes out perfect every time. So if you’re a beginner baker looking for a foolproof frosting recipe, you’re in the right place.

Whenever I make this 7-minute frosting, there are tiny sugar crystals mixed amid the fluffy velvet cream. It’s just perfection. So don’t think you did anything wrong. Just dip your spoon in again and pop it in your mouth.  Close your eyes, and enjoy the smoothness of this marshmallow fluff-like icing as it melts in your mouth.

I’d recommend watching our quick video tutorial before you start your recipe so that you can get a nice visual!

How to Make 7 Minute Frosting

Place sugar in saucepan.

 Place all ingredients into a thick-bottomed sauce pot, starting with the sugar.

You just want to use a good stainless steel pot for this, definitely not one with a nonstick coating because we are going to beat it for several minutes and all that mess would flake off and get in your icing – so don’t do that!

Add salt to saucepan.

Add salt.

Add cream of tartar to saucepan.

Then the cream of tartar.

Add egg whites to saucepan.

And the egg whites.

Tip for separating egg whites and yolks

When separating your eggs for this recipe, it is a good idea to do so in a separate bowl rather than the pot you are going to combine all ingredients in. The reason for this is that you need only the egg whites and if you get any of the egg yolk mixed in, your icing won’t turn out. By separating them beforehand, you can throw out anything that gets a yolk in it (or dig out the egg yolk if you can without combining it with the white) rather than having to throw out your entire pot of ingredients.

Add water to saucepan.

Finally, add the water. We don’t add the vanilla extract until the end.

Place over medium-low heat and beat for 5 to 7 minutes.

Place this mixture over medium-low heat (in between low and medium, so about a four on my stove) and turn that electric mixer on.

Beat this constantly for about 5 to 7 minutes, or until sugar dissolves and stiff peaks form. I use this mixer for mine. 

Continue beating until stiff peaks form.

A word of caution

Now listen, right about now you’re going to be thinking “Okay, this is crazy. This is never going to form stiff peaks. I’m sure this is as good as it will get. I might as well give up and just ice the cake.”

Note about following this recipe: The pattern on the internet these days seems to be taking a recipe, making fifty thousand substitutions and alterations to it, and then getting your tinsel in a tizzy when it doesn’t turn out exactly like the original recipe said it would. I’m not saying you would ever do that, mind you, but I do want to issue a word of caution that this is one of those recipes which really must be followed to the letter. If you go rogue, you get rogue results. Maybe those will be good, maybe those will be bad, but they won’t be on me either way.

Stiff peaks in icing.

 Look! We have stiffness! You can see how the frosting reaches and maintains the trail left by the beaters rather than sliding back into a glop. This is what we want.

Add in vanilla extract.

Now add in your vanilla extract.

Mix in the vanilla extract.

 Fold in the vanilla extract. Maintain that perfect trail left from the beaters and keep from having any of the icing sliding back down to smooth. Remove this from the heat and have a little taste of it – pure marshmallow heaven.

Storage

This icing is very stable and keeps well for up to a week on an icebox cake stored in the refrigerator. Enjoy!

Recipe Notes

  • There’s no substitute for cream of tartar for this recipe.
  • If you want to jazz up your frosting, here are some fun additions:
    • Use brown sugar instead of white sugar.
    • Fold about 3 ounces of melted chocolate chips into the finished frosting. You want both products to be at the same temperature.
    • Use a different extract flavor rather than vanilla, like peppermint or almond extract.
  • You can also torch the frosting like you would meringue.
  • You’ll need two recipes of this icing to ice a layer cake. Fortunately, this recipe doubles beautifully, so there’s no need to make two separate batches, just double it and make it all at once.

    Recipe FAQs

    What’s the difference between this frosting and Swiss meringue?

    The main difference between these frostings is that Swiss meringue buttercream frosting is cooked but mixed off the heat. Meanwhile, this frosting is mixed as it cooks on the stovetop.

    1. LOVE this recipe! It was so easy! I was asked to make a coconut cake for my boss, and I used a different recipe. The frosting didn’t thicken up right and slid right off the cake! It was such a horrible mess! Your version was so much easier and turned out perfectly! Thank you for sharing it!

    2. I made your recipe for the 7-minute frosting and it turned out exactly how one would like it. I frosted an angel food cake and put sprinkles on it and it was “as pretty as a picture”. Hopefully others had the same kind of results as I did. Thank you!!!!

    3. My boyfriend has been recalling memories of this icing from his younger years…….I have tried 2 double boiler recipes and it didn’t turn out. This recipe is perfection and came out beautifully the first try and is much easier than the others. LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!! Highly recommend it!!

    4. I made a three layer coconut cake for Easter and the 7 minute icing called for cooking your sugar, egg whites, water and corn syrup in a double boiler or glass bowl over simmering water and beat with electric mixer for 7 minutes. I had icing everywhere because I did not have a double boiler so I attempted the other method. The bowl slipped from side to side on top of the boiler, my icing poured out on the stove, the bowl was not big enough, so icing slung out everywhere. I am certainly trying this method, so I can just put all my ingredients in a boiler on top of the stove and cook and beat for 7 minutes and not have to have the double boiler or the glass bowl method? Have never heard of this and have never used the cream of tarter. Can you tell me how much cream of tarter to use with 4 egg whites, 1 1/2 sugar and 4 T. corn starch ? Am anxious to get a response from you, because I really want to MASTER this icing. Thank you so very very much.

      1. Hey Mary! That does sound like quite a mess, I’ve been there myself with recipes in the past so I can sympathize! Yup, you can just do this one right in the pot. I’m not a fan of double boilers myself :). Sounds like you want to add the cream of tartar and use this method on another recipe. I’m afraid without seeing the entire recipe and trying it out myself I can’t offer advice there. Also, they are likely trying to use the corn starch as a substitute for cream of tartar. If you can, I suggest just trying this recipe of Grandmamas as it has been very successful for us.

    5. Ok I made a different coconut cake (recipe and frosting) and it was a hit!! But decided to try yours for today my question is the other called for cream cheese, cool whip frosting..and required no refrigeration. (Which I thought was odd)
      I noticed you said good for 2 days at room temp or refrigeration for longer.. is that due to frosting?

      1. I honestly can’t imagine a cake calling for cream cheese and cool whip not requiring refrigeration. My best guess is that they simply overlooked including that in the instructions. As a Home Economics major, that is the only reasonable reason I can imagine as the cool whip, especially, is not safe at room temp for very long and the cream cheese not much longer. I tend to go more with food safety due to my background.

    6. Thank you for this recipe! I usually use a double boiler, but this was much easier. The only problem I had was I used my heavy bottom stainless saucepan and started ti ice my cake directly from the pan. I noticed lumps forming and discovered the heat held in the stainless had continued to cook the frosting and it was like a marshmallow at the bottom of the pan! Thankfully it wasn’t grainy and I used it ice a coconut cake so I just covered it with coconut…LOL! Lesson learned, remove it from the pan!!
