Marshmallow Buttercream is a remarkably light and fluffy frosting that is easy to make using only four simple ingredients. With its perfect level of sweetness, it is ideal for topping cakes and cupcakes, as well as filling sandwich cookies. For a classic buttercream recipe, try my American Buttercream Frosting.
Ingredients & Substitutions
Butter: Unsalted butter tends to be fresher and has a more consistent flavor when compared to salted butter, which can have varying amounts of salt depending on the brand.
Sugar: Confectioners’ sugar, also known as powdered sugar or icing sugar, is used in buttercream because it dissolves quickly and easily. Thus, it results in a creamy frosting like this one!
Almond Extract: Almond extract is a concentrate made from the bitter almond oil. A little bit goes a long way when it comes to adding a sweet, nutty flavor to recipes. If you don’t have any on hand, you can substitute vanilla extract. If you have a nut allergy you can also use Imitation Almond Extract which is typically not made with almonds. Be sure to check the ingredients.
Marshmallow Creme: Marshmallow creme, or marshmallow fluff, is a sweet and gooey spreadable concoction that tastes like marshmallows. Since this is a marshmallow buttercream, we can’t leave this out!
How to Use Marshmallow Buttercream
Marshmallow Buttercream is a delicious and versatile frosting that can be used to frost cakes, cupcakes, and other baked goods, as well as for filling sandwich cookies. Here are a few of my favorite ways to use it:
- Neapolitan Spritz Cookies

- Perfect White Cake
- Peanut Butter Cookies
- Chocolate Chip Cookies
- Salted Caramel Brownie Marshmallow Hi-Hats

How to Store Marshmallow Buttercream
Store marshmallow buttercream in an airtight container in the refrigerator. It will last up to a week. When ready to enjoy, first, let the frosting come to room temperature before mixing it up to get it light and fluffy again. For longer storage, freeze for up to 2 months. Let it thaw in the refrigerator overnight before using.

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.
