The BEST Marshmallow Buttercream

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.

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!

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!

  • Debra says:

    Can you pipe flowers with this recipe like a regular buttercream ?

  • Elaine says:

    I hate almond extract. Is it absolutely necessary?

    • Elizabeth Keeney says:

      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!

  • Tricia says:

    Does the 1/2 tsp of almond extract over power the frosting??

  • Rachele says:

    The butter/almond extract/powered sugar is pure powder, is this right or should there be a dash of milk?

  • Florence Mazzocchi says:

  • Elizabeth Wells says:

    This is one of my favorites

  • Nikki A says:

    Can I make this with vanilla extract? My mom is allergic to almonds.

  • Mary Reinhardt says:

    This looks amazing, have to try it.

  • Karyn says:

    I just made this exactly as written. Unfortunately, it was so stretchy? I thought it would turn out luxuriously creamy but trying to ice my three layer strawberry cake turned into a task. Not pretty. WARNING this is Not easy to ice with. Also, it is very, very sweet.

    • Amanda Rettke says:

      Very sorry you had that experience, but I cannot for the life of me figure out how it was stretchy? For future frosting making, you can always add more liquid should it be too stiff. But stretchy is not an expected response from the list of ingredients I have provided.

  • A FRUSTRATED Christine says:

    Can I use vanilla extract in place of almond extract? I thought I had some but apparently do not… or is it better to just skip ?

    • Amanda Rettke says:

      You can use vanilla instead of almond – but it will taste different. Not bad, just different. 🙂

  • Diane M Cammer says:

    Sounds great.
    Going to try it.
