Tips

  • Whip over your double broiler until it’s 160°F or until you don’t feel granules.
  • If you’re using egg whites from a carton, note that one egg white from a large egg generally equals about 2 tablespoons.*Note that we have not tested packaged egg whites in this recipe.
  • Allow cake, cupcakes, cookies or brownies to cool completely before icing.
  • Use a storage bag with the corner clipped off or icing bag to pipe, though this frosting will not be set up enough to pipe like a traditional buttercream.

Serving Suggestions

  • Toast marshmallow on the broil setting of your stove for 30 seconds or use your kitchen torch to toast it up like a dreamy s’mores dessert!
  • Take your time while it’s on the stove top to ensure it’s fully mixed and heated through.

Frequently Asked Questions

Is Marshmallow Fluff the same as Italian meringue?

The ingredients are very similar – so much so that the recipes could be used interchangeably.

What is a substitute for marshmallow creme?

This marshmallow icing is the perfect substitute, and so much more delicious.

Would this marshmallow frosting stand up to decorating?

We’ve never tested this frosting to see if it will stand up to decorating. While our images show this frosting piped onto the cupcakes, it won’t hold its shape as well as a buttercream for piping. The light and airy nature of this frosting might not hold up to heavier adornments on a cake.

Why aren’t the peaks forming in my marshmallow icing?

It’s possible that you haven’t beat it for long enough! Continue beating until it gets glossy and stiff.

Can I add food coloring to this marshmallow frosting?

While we haven’t tested it, I don’t see why not!

Can this icing go between cake layers when frosting a cake?

You can absolutely ice a cake with it as a topping, but it is not suitable to hold cake layers. Enjoy!

How to Store

  • At Room Temperature – you can store this marshmallow frosting out on the counter for up to two hours while serving.
  • Refrigerate – Because this icing has egg whites, you’ll want to refrigerate in an airtight container. It can be stored in the fridge for up to 48 hours. Note that the texture will change though, and a bit of a crust can form on the exterior of the frosting, while the interior remains soft.

Dietary Considerations

  • Gluten Free
  • Dairy Free
  • Nut Free

It's very important to be sure the bottom of the bowl holding the egg white mixture doesn't touch the boiling water.

Why is my buttercream not fluffy? ›

If it's too stiff and sticks straight up, I suggest adding in more heavy cream (1 Tbsp at a time). If it's too thin and doesn't form a little peak at all, try adding a bit more powdered sugar (1/4 cup at a time). You can also chill it in the fridge for 10-minute intervals.
