Quick and easy marshmallow frosting recipe made with 4 simple ingredients: Butter, sugar, marshmallow fluff, vanilla. It's rich, smooth, creamy, fluffy!
I made this recipe a few years ago when my kiddo asked for a frosting with marshmallows. Using actual marshmallows was a pain. So, I used fluff and it worked really well and he loved it! It can be used on cupcakes, cakes and brownies as a topping or filling. 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.

How to make easy marshmallow frosting recipe from scratch with marshmallow fluff?
- Mix together butter and vanilla extract.
- Mix in powdered sugar.
- Mix in marshmallow fluff until creamy.
- Chill and pipe on cake/ cupcakes.
Tips and techniques
- Use unsalted butter because salted butter makes the frosting very salty.
- All ingredients should be at room temperature because they will blend together smoothly.
- Vanilla extract can be replaced with any other extract of your choice.
- 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 frosting 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.
- Marshmallow fluff can be replaced with marshmallow cream to make marshmallow cream frosting/marshmallow frosting without eggs.
- For vegan marshmallow frosting, use vegan fluff or cream.
What cupcakes to pair this icing?
- White Wedding Cupcakes
- Vegan Chocolate Cupcakes

I usually freeze my frosted cupcakes until needed....can this be frozen or when it thaws will the frosting texture change?
Abeer Rizvi
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...
Abeer Rizvi
Oh that's so good to hear about the salted butter!
Janette Shaffer

Abeer Rizvi
It's real butter.

I love marshmallow fluff frosting, but can you add like instant chocolate pudding mix to make it a chocolate fluff frosting?
Abeer Rizvi
I don't know how this recipe would need to be modified to use a pudding mix. Sorry.
Rae
Can this frosting be tinted?
Abeer Rizvi
Yes, preferably with gel food coloring.
