Step-by-step instructions
- In a heatproof bowl, combine the egg whites, granulated sugar, cream of tartar, and a pinch of salt.
- Set the bowl over a pot of simmering water. Make sure the bowl doesn’t touch the water to avoid scrambling the eggs.
- Whisk the mixture constantly until the sugar dissolves and it feels warm to the touch, about 3-4 minutes.
- Remove the bowl from heat and carefully transfer the mixture to a stand mixer fitted with the whisk attachment.
- Beat on high speed until stiff, glossy peaks form and the frosting cools to room temperature, about 6-8 minutes.
- Add the vanilla extract and beat briefly to incorporate.
- Use the marshmallow frosting immediately to top your cakes, cupcakes, or desserts.
Best ways to enjoy it
The beauty of marshmallow frosting lies in its versatility. Use it to frost your favorite layer cake, pipe onto cupcakes, or even serve it as a delightful dip for cookies and fruits. Consider pairing it with chocolate cake for a classic combo or spreading it on brownies for an extra layer of decadence.
If you’re feeling adventurous, try layering marshmallow frosting between graham crackers for a quick s’mores treat!
Keeping leftovers fresh
If you happen to have any leftover marshmallow frosting—which is unlikely, trust me—store it in an airtight container in the refrigerator. It should stay fresh for up to three days. Just remember to bring it back to room temperature and whisk it again before use.
Freezing isn’t recommended, as the texture can change once thawed, but if you must, keep it in a freezer-safe container and use it within a month.
Helpful cooking tips
- Use fresh, room-temperature egg whites for the best results; they whip up better.

Creative twists
Feel free to personalize your marshmallow frosting! You can add a dash of cocoa powder for a chocolate version or incorporate different extracts to match your cake’s flavor. For a fun party treat, consider folding in mini chocolate chips or colorful sprinkles for added texture and visual appeal.
