- 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.

Love love this recipe! My grandmother made this same recipe long time ago and it’s a family favorite! Question- can this frosting be made a day ahead and stored in fridge? And then frosted next day?
I’m so glad you love it — that’s such a sweet memory! ❤️ This frosting is best made and used the same day. Because it’s an egg-white–based frosting, it doesn’t hold up well in the fridge and can lose volume or weep. For best results, I recommend making it right before frosting the cake.
I love this recipe!!
Sincerely,
Peace LoveJoy
Could cococa powder be added to this recipe? If yes, when should I add it?
You can add cocoa powder, but it does change the texture a bit. If you try it, I’d suggest sifting 1–2 tablespoons of cocoa powder and beating it in after the frosting has reached stiff peaks, right before the vanilla. Just know it may be slightly less fluffy. For the smoothest chocolate flavor, melted (and cooled) chocolate tends to work better than cocoa powder.
I just tried this recipe and doubled it as suggested for a layer cake. I do not recommend this at all. One recipe is plenty to cover the two layers with some to spare. Too much frosting and not enough cake is a waste of ingredients and time preparing. It’s good, just too much.
Thanks for giving it a go! Frosting is one of those “to each their own” things, but I’m glad it hit the spot flavor-wise.
I Love boil frosting so I add an extra egg white and 1/2 cup sugar…
I just finished mine,,,making coconut cake. Used my 10″ cast iron skillet and stainless steel stewer. This double boiler idea works great.
Don’t answer my question “does the water need to be hot”? I’ve answered it; it’s going to be cooked on the burner, of course it will get hot. My bad! Thanks!
No worries at all—happens to the best of us! Hope you enjoy the recipe.
