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!


The BEST Marshmallow Buttercream
Ingredients
- 1 cup (2 sticks or 226g) butter, softened
- 4 cups confectioners’ sugar
- ½ teaspoon almond extract
- 1 jar (13 ounces) marshmallow creme or fluff
Instructions
- Cream butter in a mixing bowl with an electric mixer on medium until butter is light and fluffy. (Can also use a stand mixer with paddle attachment.) About 2 minutes.
- Add in almond extract.
- Gradually beat in confectioners' sugar, about a ½ cup at a time. Once all is added, mix on high for 2-3 minutes.
- Once fully combined, gently fold the marshmallow creme into the frosting by hand. Can be used immediately or refrigerated until ready to use.

Can you use vanilla instead of almond extract??
Can you pipe flowers with this recipe like a regular buttercream ?
I hate almond extract. Is it absolutely necessary?
Hi, Elaine! I work with iambaker and am happy to help with questions. You can leave out the almond extract, but it will change the flavor. Have a great day!
Does the 1/2 tsp of almond extract over power the frosting??
The butter/almond extract/powered sugar is pure powder, is this right or should there be a dash of milk?
Can’t wait to try this yummy icing!! When I do, I’ll for sure share my thoughts! Thanks! Florence, G.P. TD.
Can I make my own marshmallow fluff?
Can I I use put a green color with this frosting
Yes, of course.
This is one of my favorites
Can I make this with vanilla extract? My mom is allergic to almonds.
