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 perfect—I just added a little vanilla. 🙂

It only required a small handful of ingredients, and the finished product was so tasty. It’s a really nice texture too—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. 😉

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.

    I can’t wait to try this! A couple of times in the post, you mention not wanting egg whites in your frosting, so I’m surprised you used store-bought marshmallow fluff. I’m egg-intolerant, and every store-bought brand I’ve checked contains egg whites (which is a total bummer!). If you need to avoid egg because of an allergy or intolerance, then you may want to skip the store-bought stuff and make your own vegan fluff. I found a great recipe for Vegan Marshmallow Fluff over at Chocolate Covered Katie that I’m going to pair with this recipe to make an egg-free marshmallow frosting (to go with my gluten-free chocolate cake, naturally :P).

      Hope you enjoy the frosting! Thanks for sharing the tips!

  2. Victoria says:

    Can this frosting be frozen? Thanks!

    1. Lil'Luna Team says:

      I haven’t tried freezing this frosting. It can be made ahead of time and stored in the fridge just fine. But I’m not sure how it would turn out after being thawed from frozen??

  3. Sandra S. says:

    Oh my gosh! This recipe is to die for! You must try it! Very sweet tho,! Yum!

    1. Lil'Luna Team says:

      Thank you! So glad you loved the frosting!

    This icing is so easy and so delicious!

  5. Bethany says:

    Would a dairy free butter work, such as plant butter? Thanks!

    1. Lil'Luna Team says:

      I’m not totally sure, I haven’t tried that before! You’ll have to let us know how it turns out if you use a dairy free butter. 🙂

  6. Anna says:

    Good job and thank you!! 🙂

    1. Lil'Luna Team says:

      Thank YOU for giving it a try!!

  7. Jennifer says:

    Can I use regular mini marshmallows and melt the marshmallows?

    1. Lil'Luna Team says:

      I would recommend using the actual marshmallow fluff. Or perhaps finding a copycat recipe of marshmallow fluff to substitute. Because melted marshmallows are a different texture than the marshmallow fluff in the tub, it might cause the frosting to be a lot runnier/not the right texture for frosting.

    This was super fast and easy, my family loved it. Thank you!

    1. LilLunaTeam says:

      You’re welcome! I’m glad you found it was fast and easy too. One of my favorite frostings!

      1. Kaylee says:

        Hi. Could you add cocoa powder to it so turn it brown ? Or would it change the taste/texture?

      2. Lil'Luna Team says:

        Cocoa powder would definitely turn it brown but would also absolutely alter the flavor. You’d have a chocolate marshmallow rather than a classic marshmallow flavor. You could add food coloring to get the color you want while keeping true to the flavor.

    Made this frosting this past weekend to go on peanut butter cupcakes to mimic a New England snack called a fluffernutter. It was easy to make and it’s a tasty frosting, just wished it tasted a little more marshmallowy (not sure that’s a word). I’d make it again.

    1. Lil'Luna Team says:

      Thanks for your feedback. I have heard of fluffernutters before! What a fun idea to add this frosting to recreate that.
