The Best marshmallow buttercream icing recipe
I am so excited to share with you my favorite marshmallow buttercream icing recipe that has become a staple in our household. I first discovered this recipe on a popular food blog, and I was immediately drawn to its simplicity and the unique flavor it adds to any dessert.
The combination of fluffy marshmallows and rich buttercream is absolute perfection, and my kids can’t get enough of it. Whether we’re celebrating a birthday or just need a sweet treat after dinner, this icing is always a hit with my family.
Plus, it’s surprisingly easy to make from scratch, requiring just a few ingredients and some basic kitchen equipment. In fact, I’ve found that this icing works beautifully for all sorts of desserts, from cakes and cupcakes to cookies and even fruit-topped treats like brownies or blondies.
And the best part? It’s incredibly versatile – you can adjust the amount of marshmallows to your taste, and even add in some flavorings like extracts or oils for extra depth of flavor.
I love that this recipe allows me to experiment with different flavors and textures while still delivering that classic marshmallow buttercream taste we all know and love. One of the things I appreciate most about this icing is how well it holds up at room temperature – it doesn’t melt or become too sticky, even on warm days when we’re enjoying it outdoors.
And when we do store it in the fridge (which is usually only when we have leftovers), it remains smooth and creamy without any loss of texture or flavor.

❓ Frequently Asked Questions About Marshmallow Buttercream Icing
Q: What kind of marshmallows should I use for this recipe?
A: For the best results, use large marshmallows – they’ll give you the fluffiest texture possible. You can also use mini marshmallows if you want a slightly different consistency, but be aware they may not mix as smoothly into the buttercream.
Q: Can I make this icing ahead of time?
A: Yes! This icing is perfect for making ahead – simply prepare it as directed, then refrigerate until ready to use. When you’re ready to assemble your dessert, just take the icing out of the fridge about 30 minutes before serving to let it soften slightly.
Q: How long will this icing keep in the fridge?
A: If stored properly in an airtight container in the refrigerator at 40°F (4°C) or below, this icing will keep for up to 3 days without significant degradation in quality or texture.
Q: Can I freeze this icing?
A: Absolutely! To freeze, simply scoop the prepared icing into an airtight container or freezer bag and store at 0°F (-18°C) or below for up to 2 months. When you’re ready to use it again, simply thaw overnight in the fridge before whipping as directed.
Q: Is there a substitute for butter in this recipe?
A: While traditional unsalted butter works beautifully in this recipe, you can also use a dairy-free alternative like vegan butter if needed. Keep in mind that these substitutes may affect the flavor slightly – if you prefer a more neutral-tasting butter substitute, consider using coconut oil instead.
