Want to Jazz Up Your Frosting? Try These Ideas
- 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 instead of vanilla, such as peppermint or almond.
- You can also torch the frosting like you would with this coffee pie with meringue.
How to Make 7 Minute Frosting
1. Add Ingredients to a Pot
Start by adding your sugar to a thick-bottomed sauce pot.
Pro tip: You’ll 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!
Next, add the salt, then the cream of tartar and the egg whites.
Pro tip: When separating your eggs, do it in a separate bowl first. The icing won’t turn out if even a little bit of yolk gets mixed in with the whites. This way, if a yolk breaks, you won’t have to waste all your ingredients.
Finally, add the water. We don’t add the vanilla extract until the end.
2. Heat & Beat
Place this mixture over medium-low heat (about a 4 on my stove) and then turn the electric mixer on.
Beat this constantly for about 5 to 7 minutes, or until sugar dissolves and stiff peaks form.
A word of caution
Right now, you might 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.”
Don’t! This is one of those recipes that must be followed to the letter. If you go rogue, you get rogue results. Maybe they’ll be good, maybe they’ll be bad, but they won’t be on me. Stick with it, I promise it’ll work.
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.
3. Fold in the Vanilla
Now add in your vanilla extract and fold it in. Maintain that perfect trail left by the beaters and keep any icing from sliding back down to smooth. Remove this from the heat and have a little taste of it – pure marshmallow heaven.
Ice your cake with this 7-minute frosting, and you’re good to go.
Oh my goodness, how light and fluffy does that look?

Does this frosting need to be refrigerated?
No, you don’t need to refrigerate this frosting! I’ve found that a cake frosted with this recipe will be perfectly fine covered on the counter for up to two days. After that, the frosting will start to melt into the cake. I suggest making and frosting the cake the day you are going to serve it for the best results.
7-Minute Frosting FAQs
The main difference between these frostings is that Swiss meringue buttercream is cooked, then mixed off the heat. Meanwhile, this frosting is mixed as it cooks on the stovetop.
If you just toss that granulated sugar into your egg whites, it won’t dissolve properly. You’ll end up with a gritty frosting, and nobody wants that! By taking a minute to make a simple syrup first, you ensure that sugar melts down nice and smooth, giving you that silky, fluffy frosting we’re aiming for. It’s a small step that makes a world of difference.
It’s normal for this 7-minute frosting to have tiny sugar crystals mixed amid the fluffy velvet cream. This is part of the frosting’s texture, so don’t worry, you haven’t done anything wrong! The crystals add to its unique, fluffy, velvet-cream consistency. Just close your eyes and enjoy the smoothness of this marshmallow fluff-like icing as it melts in your mouth.

Did no one else think this was too salty? 😮
I believed you used the wrong measuring spoon. Instead of the teaspoon (tsp)…I believe you used the tablespoon (tbs). Hope you’ll give this recipe another chance
I tried it without a double boiler and even though I had the burner on 4, eventually the sugar started to stick and made brownish flecks in the icing. Very unappetizing.
I just made this but mixed it in a glass bowl placed on a pot of boiled water on simmer rather than directly in a pot. Added lemon extract instead of vanilla. Worked great. Yum! Was also able to pipe it onto some lemon cupcakes.
Great idea Brenda and am so glad you loved it!! Thank you for the comment and the rating 🙂
Happy Holidays to you and yours
My mom used the corn syrup recipe but she also beat in about 5 or 6 marshmellows
I followed the recipe with exact measurements to a T and ended up A) beating for 10 minutes but only getting soft peaks and B) being able to taste the cream of tartar… I’ve never made 7 minute frosting before but I use italian meringue quite a bit and it always turns out without that slight sour taste, though I do use less in that recipe. I definitely understand its importance but has anyone tried maybe halving the c/t and using corn syrup as well as shown in other recipes?
Can this be made into lemon frosting with lemon juice or extract? My father in law talked about a chocolate cake his mom used to make with fluffy lemon frosting. I so want to try it for him! They are from the south so any advice would be appreciated- I cannot find a recipe for this!!!
Hi Julie thanks for the question. I haven’t made it into lemon frosting but I don’t see why it couldn’t be!
I would add in a couple tablespoons of lemon juice
and maybe a tsp or so of lemon zest. That is where I would start. I haven’t made it with lemon though so please let me know how it turns out. Anyone else made with lemon, please chime in!
I believe you can use ANY good extract. I used McCormick Coconut. Same amount needed in the recipe EXCEPT I used the coconut flavoring instead of the vanilla.My 96 year old Uncle wanted a coconut cake like his Mama made for him on his birthdays. Once I iced the cake I sprinkled coconut all over. It truly IS my Grandmother’s cake.
Easy enough. I selected it because I didn’t have a double boiler most recipes recommend. The problem was the sugar browned on the bottom ( I used medium as suggested) so the whole batch was cream colored with brown flecks in it. A problem that would not have happened with a double boiler.
Not very appetizing… Wouldn’t use it again.
Thanks for letting us know how it turned out. Every stove is different unfortunately so medium heat on one may be hotter or less so than another. Hope it tasted good!
