As most of you know, I like simple, easy recipes. When researching this Marshmallow Fluff Frosting I found that a lot recipes had unnecessary ingredients. Such as egg whites, cream of tartar and granulated sugar.

You also had to simmer water in a double boiler which is another step that is unnecessary. I love that this recipe only requires 4 ingredients and it is a simple process to make.

Marshmallow Fluff Frosting is a great frosting to make ahead. It stores perfectly in the refrigerator. Since there are no egg whites, you can make this frosting several days ahead of time.

You can also go ahead and top your cupcakes and store them in the refrigerator until you are ready to serve.

Can I add in Mix-ins?

Yes, you can. This frosting is good but adding in some mix-ins would take this frosting to a whole new level.

  • Add in some toasted coconut. We love coconut and it would be great on top of a German Chocolate Cupcake.
  • Chocolate Chips is a great addition to the frosting.
  • Chop up with strawberries or other fresh fruit and mix into the frosting.
  • I have even mixed in some peanut butter powder to the frosting when I make chocolate cupcakes.

Since this frosting is so easy to make. Invite your family and friends over for a holiday party. Have a frosting bar with different toppings. This way everyone can make their own.

How much frosting does this recipe make?

This recipes makes enough to frost 12 cupcakes. Using a piping bag it should cover all 12 of your cupcakes. If you are spreading the frosting on with knife on your cupcakes, then it will probably cover more.

Covering a 9×13 you will need to double to recipe. You will also need to double it if you are a frosting two 8×8 round cakes.

Tips for the best Marshmallow Frosting:

  • We like to use piping bags and decorative bags and then toss when finish. Using piping bags makes easy to frost the cupcakes and easy cleanup.
  • Use a stand mixer to beat the powdered sugar and butter. It makes is so much easier than doing it by hand. I do recommend mixing in the marshmallow fluff and vanilla by hand.
  • Remember if you frosting is to thin add more powdered sugar slowly. But if it is to thick you can thin it out with milk.
  • Do not substitute melted marshmallows for marshmallow fluff. It will change the texture and the frosting will not set.
  • Always make sure the butter is fully softened. This helps it to mix well with the powdered sugar.
  • If you are using milk, make sure you are adding in a little at time.
  • We do not recommend freezing this frosting. It works best if you use it after making it or storing in the refrigerator for a few days.

How to thicken the frosting?

If you find that your frosting ends up being to thin, add in some powdered sugar. We start with about a tablespoon of powdered sugar at a time. Then stir in the additional powdered sugar if needed.

You might need to add a little each time to get the consistency that you want.
