I adore the texture of this frosting. It is truly one of the lightest and fluffiest buttercreams I have ever made! Four easy ingredients and a little mixing and you are ready for this dreamy, creamy Marshmallow Buttercream! For a classic buttercream recipe, try my American Buttercream Frosting.

Marshmallow Buttercream

This is one heckuva sweet frosting! Butter, sugar, almond extract, and marshmallow cream are all you need to make it… and those ingredients combined are absolutely sweet! Don’t be afraid by all that butter in there. I know I was before I tried it! But with the addition of the almond extract, it truly is delicious. Why almond extract? It truly is my secret ingredient in making frostings BETTER and absolutely lives up to its reputation in this recipe.

Uses for Marshmallow Buttercream

This buttercream lends itself so well to all varieties of sandwich cookies. Here is my Neapolitan Spritz Cookies, however, it would also be amazing with Peanut Butter Cookies or Chocolate Chip Cookies! I used half of the recipe for my Salted Caramel Brownie Marshmallow Hi-Hats, too.

And of course, its the perfect frosting for Cake. This recipe works beautifully for one 2-layer cake, like this Perfect White Cake. It is also the perfect complement to my Ginger Sandwich Cookies!
