Seven minute frosting is a light and fluffy Swiss meringue frosting made from cooked egg whites and sugar that tastes like marshmallow cream!
This recipe is the seven minute frosting that I grew up on. This frosting was the frosting that my mom used on our coconut cakes at Easter and Christmas.
This version is really easy to make! It's also delicious. It reminds me of an airier marshmallow cream.
I've included step-by-step photos, plenty of tips, and lots of other information to help you make perfect light and fluffy seven minute frosting!
What is seven minute frosting?
Seven minute frosting (or boiled frosting or white frosting) is basically a Swiss meringue frosting. It's a frosting made from cooked egg whites and sugar.
The frosting is whipped as it cooks and has a light and airy texture that's similar to a fluffier marshmallow crème.
How to make
Add the egg whites, sugar, corn syrup, water, salt, and cream of tartar to the top of a double boiler. Place top pot over rapidly boiling water.
Beat the egg mixture with a hand mixer on low for 30 seconds.
Increase the speed to medium-high, and continue mixing until the egg mixture stands in peaks (see the picture just below).
Remove from heat. Mix in vanilla extract.
Use immediately to frost your cake or cupcakes.
What should peaks look like?
The peaks should stand straight up when you lift the beaters out of the frosting. The peaks shouldn't droop or curl over.
Tips
Egg whites: I use cold, from the fridge egg whites. It's really important that you don't get any yolk in the egg white when separating, though, because the frosting won't whip up right with yolk in it.
Corn syrup: Unfortunately, I don't have a good substitute for the corn syrup in the recipe.
Double boiler: If you don't have a double boiler, check out my section just below for tips on faking a double boiler.
Salt: A couple pinches of salt help to add balance to the frosting.
Cream of tartar: The cream of tartar helps to stabilize the frosting.
How to fake a double boiler
There are a couple of ways to make a makeshift double boiler.
Pot-on-pot
You can stack two pots together. The lower pot will hold the boiling water, and the upper pot will hold the frosting ingredients.
If you stack the pots, it's important that you don't use a pot with a nonstick coating that will come off while you're mixing the frosting.
Bowl-on-pot
You can also use a heat-safe metal or glass bowl placed over a pot of boiling water (pictured in the step-by-step how-to section above). I think this method is a little easier because it gives you more room to mix the frosting while it cooks.
>>Top tip: It's important that you don't let the bottom of the bowl or pot touch the boiling water.
Serving suggestions
Seven minute frosting pairs beautifully with coconut cake. It's also good with yellow cake, white cake, or chocolate cake.
Storage
I recommend storing any leftover frosting or frosted cake covered loosely in the fridge. This frosting doesn't hold up as well as a buttercream, and it's best eaten in the first 2-3 days after it is made.
