No hassle, just quick & easy!

For the most recent cupcakes I made, I decided I wanted to use Marshmallow Frosting. I did a few google searches but found only ones that involved egg whites and decided I needed a quick and Easy Marshmallow Frosting.

I had remembered I saw one on Pinterest one day. It was from Just a Pinch. I usually modify all recipes, but this one was already nearly perfectโ€”I just added a little vanilla. ๐Ÿ™‚

It only required a small handful of ingredients, and the finished product was so tasty. It’s a really nice texture tooโ€”not too thin and “whipped”, but not too dense like some buttercream frostings. I’ve used it on multiple flavors of cupcakes already!!

Just 4 ingredients!

This recipe is so easy because it only uses 4 ingredients (and egg whites is NOT one of them!!):

  • butter (make sure it’s at room temperature)
  • marshmallow fluff
  • powdered sugar
  • vanilla extract (extract, not flavoring)

If you’re having a hard time finding the marshmallow fluff, check in the baking isle of your grocery store. The label might also say “jet puffed marshmallow creme”. This works the same! If you still don’t have any luck, Amazon is always on option. ๐Ÿ˜‰

When you’re mixing the ingredients together, make sure the powdered sugar and butter are completely creamed together before adding anything else. There should be no visible clumps of powdered sugar.

Use a rubber spatula to scrape any stray clumps from the side of the bowl, and to mix in the fluff by hand (rather than using a beater/electric hand mixer).

Tips, tricks, and troubleshooting

How much this frosting will cover depends on how you use it. If you’re piping it on, or being really decorative, this recipe makes enough frosting to cover 12 cupcakes. If you are spreading it on with a knife, it will cover several more.

You can use it to frost a cake, however you might need to double the recipe for a 9×13 cake, or for a double layer 8 inch round cake.

I’ve had several readers ask if you can use a kitchen torch to brown this frosting (kind of like a toasted marshmallow). Although I have never tried, one reader said it does work if you use really high heat up close. If you’re too far away, the frosting will melt before it browns.

Make ahead and store? Because this recipe is more of a buttercream type frosting, and doesn’t have egg whites in it, you can easily make it in advance and store in the fridge for several days before using. As long as it is kept cool, it will stay in good condition.

You can even frost your cupcakes a day or two in advance, and keep in the fridge until you’re ready to serve.

If your frosting is too runny, you might need to add a bit more powdered sugar to stiffen it up. I wouldn’t add more than a couple tablespoons at a time, and then mix well to see how it affects the consistency.

Areas that are warm or humid might affect the consistency of your frosting as well. Put it in the fridge for a while to see if that does the trick.

    If you use 1 cup butter and 2 cups powdered sugar it turns out great. Its just the regular marshmallow creme 7 oz.
    No eggs

    1. Lil'Luna Team says:

      Thank you for sharing that ๐Ÿ™‚

  5. Mer says:

    I feel that I followed the recipe perfectly however my marshmallow fluff frosting is not stiff enough to pipe and I fear that spreading it will be a mess.

    1. Kristyn Merkley says:

      You could add more powdered sugar to thicken it a little. Hope that helps!

  6. Patricia Smith says:

    Did you use salted or no salt butter?

    1. Kristyn Merkley says:

      I like to use unsalted butter when I bake ๐Ÿ™‚

  7. Towles Kintz says:

    Hi – Can I make this frosting a day in advance, or should i only serve it on the day-of? Thanks!

    1. Kristyn Merkley says:

      I would do the frosting the day of, but that’s me. It should be ok, if you made it ahead.

    Just wanted to fill answers for lots of comment questions! I made this with marshmallow creme instead of fluff (creme is all that’s available in Arizona), and it turned out great. I tried torching it, and this does brown nicely before melting.

    To make the frosting, make sure the butter and powdered sugar are completely creamed together, not just mixed. This took a long time with my hand mixer but eventually turned beautiful.

    For toasting the marshmallow make sure you use really really high heat. I used a butane torch for bruleing sugar and if it is held too far away the frosting will melt before it browns. Get really high heat right on the frosting.

    1. Cameron says:

      Forgot to mention that I put the frosting in a bag and let it sit in a cooler about an hour before using it (not on purpose, I just didn’t have time). The frosting held up for a whole day at winter room temperature, then After leaving cupcakes in the fridge for a few days it is still looking good.

    2. Kristyn Merkley says:

      Thank you so much for sharing that, Cameron! Hope that helps someone ๐Ÿ™‚

    1. Kristyn Merkley says:

  10. Anne Monsees says:

    Can i frist cupcakes the day before serving?

    1. Kristyn Merkley says:

      You could. I have not, so I am not totally sure how the frosting will hold up, though.
