7 Minute Frosting Recipe

Delicious, light, and perfect for all sorts of cakes!

I've started quite the collection of frostings on this site. And with each one I add, the recipes just get better and better. Take this 7 minute frosting for example.

It has to be my most favorite. It's basically marshmallows in frosting form. I used it to top banana pudding cupcakes because it resembles the meringue topping on the classic banana pudding dessert.

It's made with egg whites, granulated sugar, corn syrup, and vanilla. There's no butter or loads of powdered sugar in this recipe. While I love buttercream frosting, sometimes it can be too rich and too sweet.

Today's marshmallow frosting solves all those problems!

You need a stainless steel or any heatproof bowl. Put all the ingredients in, except for the vanilla, and whisk it continuously as it heats over a saucepan of simmering water.

I find an electric hand mixer to work best for this.

Once the frosting thickens, remove it from the heat. It takes about 5 minutes for it to thicken. Add the vanilla and continue to beat it until it's thick but spreadable.

This usually takes around 2 minutes. A total time of 7 minutes!

This recipe shiny and feels silky on the tongue. It's not overly sweet and has hints of vanilla. This makes it perfect for filling and icing ultra sweet, flavorful cakes.

It isn't good for piping because it's soft. So you'll need to use an offset spatula to spread it onto the cake instead of piping it.

However, it does hold well when using a large round top to pipe dollops of frosting on cupcakes. But it won't hold intricate designs.

I bet this frosting would amazing on this s'mores cake!

Tips for frosting success:

  • Make sure the egg whites are at room temperature.
  • Use an electric hand mixer so your arm doesn't tire out from whisking.
  • Once it has cooled to room temperature, use it immediately.

My grandmother made a frosting that she called 7-minute icing. It had no corn syrup and no powdered sugar. No milk. No dreaded sugar grains. And, it hardened on the outside. Was a perfect balance for a Devil’s Food cake as well as white cake. So is this the same recipe? If not, what is it and where do I find it? I guess I should have listened closer. 😁Thanks

@Betsy Rall, Yes, seven min frosting should have a slight thin crust after its been on the cake a while. Sooo good. This recipe is perfect.

I'm not sure if this is the same recipe since I don't know your grandmother's recipe but it sounds similar. Mine contains corn syrup and doesn't turn hard on the outside. It's more like marshmallow frosting.

Hi, is this frosting that will have crust after a few hours?

@Jen Sobjack, traditional properly made Seven Min frosting should form a slight crust after its been on the cake a while. This is one of the best parts about 7 min icing and it lets you know its been done right. Yummy!

No. That would be a buttercream frosting. This is more like meringue.

Hi Jen!

I would love to try whip this frost to cover my Grandma's chocolate Birthday cake this coming weekend. I want to avoid stuffing my grandma with the overly sweet buttercream frostings! Before I do, I've got a few questions to ask.

1. After frosting & placing it in the fridge, how long will the frost last after you remove it from the fridge? will it be able to be out (in an air-conditioned indoor area) for 2-3 hours before we cut it?

2. Does this frost on the cake hardens or remains soft to touch after removing from fridge?

3. Would you recommend this 7 minute frost or swiss meringue buttercream frost for the cake?

sorry for asking too many questions! Im excited to try but I worry too much (almost about anything and everything)! thank you & stay safe!

Hi Diyanna! I'm happy to answer your questions. The frosting will be okay for a couple of hours after removing from the fridge but it may start to sweat. This could be undesirable. The frosting doesn't crust over so it's not going to be hard per se. It's more like a super-soft marshmallow texture once it's been refrigerated. So expect it to be firm but not hard. I would honestly choose the Swiss meringue buttercream since you're not planning to serve the cake immediately after frosting it. Save the 7-minute frosting for a cake that you plan to serve immediately once frosted.

Hi. Can I use this frosting recipe to cover a whole cake (eg. for birthdays or wedding cakes)?

Jen Sobjack

Yes, this frosting is meant for cakes and cupcakes. Once frosted, serve within 12 hours or refrigerate the frosted cakes for up to 2 days.

So if I use this to frost a 2 layer cake long before it starts breaking down?

Once you frost the cake it must be served within 12 hours or refrigerate it for up to 2 days.
