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.

    My daughter’s 4th birthday is tomorrow. She requested a candy cane marshmallow cake so I’m going to try this!

      Hope she likes it! Tell her Happy birthday! Thank you!

    I’ve been making this for many, many years. It is my 9 grandchildren’s favorite frosting. I got the recipe from one of the “women’s” magazines many years ago. They also had chocolate version we did not care for. All ingredients are exactly the same, your difference is the order of incorporating the ingredients.

    1. Kristyn Merkley says:

      Glad they like it!! Thank you for letting me know 🙂

    I haven’t tried this yet, but I plan to. I was wondering if you thought it would work with extracts other than vanilla (such as lemon or almond). Have you tried that?

    1. Kristyn Merkley says:

      I personally have not tried, but if you do, I’d love to know what you think!

    Super delicious! Used as filling and frosting for chocolate cupcakes. I added some extra sugar and it piped ok, but the piping doesn’t fully hold it’s form. I’ve found the same with any other fluff based recipe I’ve used though.

    1. Kristyn Merkley says:

      Thank you for sharing that! Glad you tried it!

    Simple and wonderful!

      Glad you think so 🙂 Thank you!

    Ok, I made a triple recipe. The texture was AWESOME and the flavor was on point… but it was so sugary. Is there any way I can cut back on the sweetness? It was also very sticky and hard to stir, but that’s my fault for making so much.

    1. Kristyn Merkley says:

      I’m not really sure what I would cut back on, unless there were sugar-free options.

    Used this for a swiss miss hot cocoa mix I picked up. It is perfect! Delicious and super easy. Will make again for other cakes, too.

    1. Kristyn Merkley says:

      Good to know! I will have to try! Thank you so much!!

    Found a recipe for gingerbread oatmeal cream pies and would like to use this for the filling. Do you think it would be stable enough? Have read some comments about I being a bit runny. Any suggestions besides additional powdered sugar? I love the idea of a marshmallow cream filling for these cookies so hope it works out!!

    I made this frosting to go atop pumpkin cupcakes and found it to be too sweet and I wasn’t a fan of the texture. It did pipe and hold it’s shape well. While it worked for my need, I probably wouldn’t make it again.

    1. Kristyn Merkley says:

      Thanks for trying it 🙂
