    I made this recipe a few years ago when my kiddo was obsessed with marshmallows. Using actual marshmallows was a pain and that's why I used fluff and it worked really well and he loved it. Keep in mind that this is not a toasted frosting, which means you cannot use a torch on it because it will melt into a sticky mess. If you like white icings, be sure to also make this yummy Almond Buttercream Frosting.

    Key ingredients

    • Butter- This should be unsalted and at room temperature.
    • Vanilla extract- You can use other flavors of extracts too.
    • Powdered sugar- Sift it if you have time to remove any lumps.
    • Marshmallow fluff- Don't use a homemade version. You have to use the jar from stores.

    How to make easy marshmallow frosting recipe with marshmallow fluff?

    1. Mix together butter and vanilla extract.
    2. Mix in powdered sugar.
    3. Mix in marshmallow fluff until creamy.
    4. Chill and pipe on cake/ cupcakes.

    Variations and tips

    • Use unsalted butter because salted butter makes the frosting very salty.
    • All ingredients should be at room temperature because they will blend together smoothly.
    • If the frosting is too thin, add more powdered sugar (¼ cup at a time) to thicken it up.
    • If the frosting is too thick, add a little milk (1 teaspoon at a time) to thin it out.
    • This icing is sweet and thus, it’s best paired with cake and cupcakes that are not too sweet.
    • The consistency of this frosting is different and not suitable for many decorating techniques, especially the intricate ones.
    • Don't replace marshmallow fluff with actual marshmallows because the result was not the same and it  took longer to melt the marshmallows and then use them.
    • Chilling the frosting before piping makes it easier to handle and the frosting swirls hold their shape better.
    • For vegan version, use vegan fluff or cream.
    • Marshmallow fluff can be replaced with marshmallow cream. Many places use those terms interchangeably.
    • Vanilla extract can be replaced with any other extract of your choice.
    • Use gel colors to tint the icing to any shade you like.

    What cupcakes to pair with this icing?

    • Cupcakes- Pipe on top of White Wedding Cupcakes, Chocolate Cherry Cupcakes, Orange Cupcakes, Vanilla Cupcakes and Coffee Cupcakes (Mocha Cupcakes).
    • Cakes- Pair with Chocolate Pound Cake and Chocolate Cake Roll (Cake Mix).
    • Brownies and bars- Top it off on these Nutella Brownies and these Brookies (With Brownie Mix).
    • Cookies- Tastes delicious on this Chocolate Thumbprint Cookies

        I never freeze frosted cupcakes. I freeze the cupcakes and frosting separately in sealed freezer bags because I feel like frozen frosted cupcakes have an unusual texture. If you try it out, let me know how it goes.

      I did not have unsalted butter so I used salted butter and there was absolutely no salty taste. I used this frosting on a yellow cake and it was delicious. Had Bonnie Bell Raspberry Fudge Brownie ice cream with it. OH YUMMY...5 stars

        I don't know how this recipe would need to be modified to use a pudding mix. Sorry.
