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.

    I wonder if this is similar to a recipe I have that contains Cream Cheese mixed with Marshamellow Fluff. I haven’t made it in a long time but it was great as a fruit dip at parties.

    1. Lil' Luna says:

      Ooooh, that sounds delicious to me!! I will have to give that a try next time I make Fruit Dip. ๐Ÿ™‚

  2. Shonie Castaneda says:

    Can you bake a cake ahead of time, ice it with the Easy Marshmallow Frosting, then freeze it? If so, if you color the icing(to decorate), will it bleed after taking it out of the freezer?

    1. Lil' Luna says:

      You know what… Unfortunately, I couldn’t tell ya. I have never tried it. If you do end up trying it, let me know how it goes so I can know for the future. Good luck!

      1. Trina says:

        Does this cake need to be refrigerated at with the icing

  3. Mimi says:

    Has anyone tried this with less butter! A cup seems like a lot. Looks delicious, though!

    1. Angela says:

      4 stars
      Duh it only calls for a 1/2 cup of room temp butter unsalted butter sticks are best for baking recipes and frostings

  4. Anna says:

    Hi there! I Thanks for the recipe, it was very easy to make. I just made it but I’m not sure if it came out right. It looks good, but it tastes like only butter and it’s kind of disgusting. Would I be ok to add more fluff or would it not change the flavor?

    1. Megan says:

      Mine tasted like just butter and the consistency is very buttery. I tried adding more powdered sugar and some milk. It helped a little but I didn’t think it tasted like marshmallow at all. I loved how it spread though, it was very easy to decorate with.

      1. Lil' Luna says:

        So sorry you had a problem with this. Next time I would add more marshmallow fluff to see if that helps. ๐Ÿ™‚

    2. Angela says:

      Recipe called only for half of a cup of room temp butter! Try unsalted baking butter sticks less rich

  5. Blair says:

    Mine came out really REALLY thick and sticky and it was really hard to spread. What happened?

  6. Kayla says:

    Mine came out really wet. No way this could stand up on a cupcake. I even added a second container of fluff. It was still very wet and runny. Not happy!

    1. Jordi says:

      Mine did the same thing… Maybe I used creme instead of fluff? If there is a difference… Mine was more like a glaze but still yummy

      1. Miranda says:

        You can add more powdered sugar to the recipe ๐Ÿ™‚ thats what I did, just two tablespoons.

    Marshmellow Fluff has egg in it!
