Marshmallow Frosting Recipe

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 fluffy marshmallow frosting 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!

Use this marshmallow frosting for cupcakes, cakes and brownies as a topping or filling.

Keep in mind that this is not a toasted marshmallow frosting and you cannot use a torch on it because it will melt into a mess.

Tips for marshmallow frosting recipe from scratch:

  • 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 (1/4 cup at a time) to thicken it up.
  • If the frosting is too thick, add a little milk (1 tsp 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.
