7-minute marshmallow frosting

Remember those birthday cupcakes I mentioned in my last post? Well, I’m going to start by sharing my recipe for the best marshmallow frosting ever. Even better? It only takes seven minutes to make (no joke). Think of this as a cupcake cliffhanger.

Six years ago when creating that ring ding cake for Mikey, I made a seven-minute icing to use as the filling. What I loved most about the recipe is that it was no-cook. Most seven-minute icing recipes call for making a simple syrup of water and sugar, then drizzling it into the egg whites while beating them. I don’t like extra, unnecessary steps, and this is one case when it’s really wasteful from a time perspective. Cleaning dishes is also one of my least favorite chores, so if I can save time and have one less pot to wash, then it’s a double win.

The stakes were pretty low here. There wouldn’t too much in the way of wasted ingredients or time if it didn’t work, so I gave it a go.

Looking at the photo below, you can see it works like a charm. Billowy, cloud-like, yet firm peaks of meringue-like icing. I told you, the best marshmallow frosting!

Forgive me while I sidetrack a moment here. Have any of you ever wondered what the difference is between icing and frosting? Yeah, me too. According to Williams-Sonoma, icing is usually thinner, glossier, and meant to act as a glaze. Frosting is thicker, fluffier, with more texture for coating cakes. By this definition, seven minute icing should be frosting, not icing, right?

Okay, so back to this recipe. While frosting the cupcakes (chocolate buttermilk recipe coming soon!!!), I got lost in the swirls and peaks while frosting them. The texture was so much like marshmallows, and I wondered…since this was a meringue-like frosting after all, could I run them under the broiler for a toasted marshmallow effect?

The answer is YES. So, that leads to my next question, why do we call it seven-minute icing when really it’s marshmallow frosting? I mean, doesn’t the sound of marshmallow frosting just make your knees all weak? And marshmallow frosting that only takes seven minutes to make; well that’s a win-win.

Now, if you decide to toast the top of the your frosting, keep a close eye on the broiler. They’ll easily go from beautiful to burnt if you don’t watch them like a hawk. To do this for a cake, I’d suggest using a torch so you can get the sides nicely toasted, too.

Before toasting, the frosting is silky smooth. After toasting, it firms up slightly, and really takes on more of a soft, spongy marshmallow consistency. The girls went crazy for these cupcakes, and were incredibly generous with their “wow, you’re a genius, mommy” compliments. They are two hard-to-please customers, and on a day that was filled with many mixed emotions, their squeals of delight were exactly what my heart and soul needed to feel nourished.

    Jennie, you’re a genius! Alton Brown would be proud of your scientific approach and I will definitely give this a try. My sister’s birthday coincides with the Easter season and her birthday cake growing up was often Angel Food, with Pink 7 Minute Frosting and marshmallow peeps around the base. Good memories.

    Dottie, that is the ultimate compliment; I think Alton Brown is the bees knees! And that cake, it sounds so fun. I might have to try it out for my girls one day.

    Hmm… my mom’s birthday is this weekend and now you’re giving me ideas…

    This sounds/looks delicious. And that video pairing absolutely made my day! I’m thinking your kids are right about you being a genius… 🙂

    Marshmallow frosting is my absolute favourite for whoppie pies but as you stated, the work involved in making a traditional 7 minute frosting makes it a bit of a project. Can’t wait to try this – maybe tomorrow!

    I’ve so been craving whoopie pies, too. Long story, but that’s kind of how I ended up baking cupcakes. We brought home whoopee pies from a local restaurant, and they were awful, so we needed a quick stand in for papa’s birthday.
