When I was creating my S’mores Cake Recipe, I thought it would be amazing to pipe some pretty marshmallow fluff on top and toast it. The problem was, the jar of Kraft Marshmallow Creme I started with in recipe testing was not pipeable and quickly lost its shape, melting into pools of goo all over the cake. It was a happy accident though, because instead I concocted a homemade version that is pipeable, holds its shape perfectly, and looks amazing when toasted! And this homemade Marshmallow Meringue is so tasty, you’ll forget all about that store bought stuff.

You can totally frost an entire cake with this Marshmallow Meringue, but my favorite way to use it is for piping pretty accents and toasting them with my kitchen torch. The toasted portions of my S’mores Cake Recipe, S’mores Cupcake Recipe, and Banana Nutella Cake all feature this recipe. You don’t have to stop at accents though – this Marshmallow Meringue is super light and fluffy, making it perfect as a filling or frosting for cakes and cupcakes. Feel free to get creative!

There are only four ingredients in this recipe, but they’re all super important. When whipped, the egg whites give structure, the sugar helps bind it all together and sweeten it, the vanilla is responsible for making it taste like marshmallowy goodness, and the cream of tartar helps it hold its shape. Don’t skip the cream of tartar! I know it might be tempting, but it’s truly a must.

This Marshmallow Meringue can be made ahead, but if you want the best consistency for piping and frosting, I recommend using it immediately. That means if you want to use it with any piping tips or frost a cake with pretty peaks, you’ll want to whip it up as a last step in your decorating process vs. a make-ahead recipe. You can store the Marshmallow Meringue for up to two days in the refrigerator if you’re planning on using it as a filling, it just won’t be as spreadable and easy to work with for frosting and piping.

My favorite part about using Marshmallow Meringue is breaking out my kitchen torch and toasting it. It’s exhilarating! If you’re in need of a good butane kitchen torch, here is the one I use. I’ve tried using other things to toast (matches, a lighter, etc), but nothing holds a candle to a trusty kitchen torch. So if you want to toast this meringue, you’ll need one. Something that does not work for toasting this Marshmallow Meringue? The oven. It’ll melt your meringue into soup, so don’t even think about it.

Print Recipe Pin Recipe

Cook Time:10 minutes mins

Servings: 4 Cups

Ingredients

  • 4 large egg whites
  • 1 Cup (200g) granulated white sugar
  • 1/2 tsp cream of tartar
  • 1 tsp pure vanilla extract

Instructions

  • Fill a medium saucepan with an inch or two of water and bring it to a simmer over medium heat. Whisk together the egg whites, granulated sugar, and cream of tartar in a heatproof bowl, then place it on top of the simmering saucepan. Make sure that the bottom of the bowl does not touch the water. Alternatively, you can use a double boiler for this part.

  • Whisk the egg white mixture continuously until the sugar and cream of tartar are dissolved, about 4 minutes. It will thin out and be very frothy on top.

  • Remove the mixture from the heat and add it to a stand mixer fitted with the whisk attachment (you can use a hand mixer for this part as well). Add the vanilla, then beat on high speed for about 5 minutes. You’ll know it’s ready when it looks glossy with stiff peaks. To test it, dip your whisk attachment into the meringue and make sure the peak holds.

  • Use the Marshmallow Meringue immediately on cakes, cupcakes, or any dessert. You can frost with it, pipe with it, use it as a filling, or whatever you’d like before toasting with a kitchen torch (it tastes great untoasted too though).

Notes

Make Ahead Tips

  1. If you’re planning on using this Marshmallow Meringue as a frosting or piping with it, I do not recommend making it ahead. Instead, whip it up right before you’re planning on frosting or piping. If you’re using it as a filling, you can store it in an airtight container in the refrigerator for up to two days.
  2. After topping your baked goods with Marshmallow Meringue, you can store them at room temperature for up to 6 hours, after which I recommend storing them in the refrigerator. Do not freeze.
