Ingredients You’ll Need

Each component plays an essential role, whether it’s adding stability, sweetness, or a burst of pure flavor. With just a handful of pantry staples, you’re all set for a frosting adventure that feels both luxurious and approachable.
- 4 large egg whites (room temperature): These provide the airy structure that gives the frosting its signature fluffiness.
- 1 cup granulated sugar: Sweetens the frosting and creates the glossy finish when dissolved properly.
- 1/4 teaspoon cream of tartar: Stabilizes the egg whites, helping them hold those beautiful stiff peaks.
- 1 teaspoon pure vanilla extract: Adds warmth and depth, elevating the simple sweetness with a rich aroma.
- Pinch of salt: Balances sweetness and enhances overall flavor complexity.
- Optional: 1/2 teaspoon almond extract: For a subtle nutty twist that pairs beautifully with many cupcake flavors.
- Optional: 1/4 teaspoon lemon juice: Brightens the frosting with a gentle zing and freshens the finish.
How to Make Marshmallow Frosting for Cupcakes Recipe
Step 1: Prepare the Double Boiler
Start by filling a saucepan with about 2 inches of water and bring it to a gentle simmer. You’ll use this to create a double boiler effect that heats the egg whites and sugar mixture gently and evenly. This slow heating is what dissolves the sugar completely, ensuring a smooth, glossy frosting free of graininess.
Step 2: Combine Ingredients and Whisk
In a heatproof bowl, whisk together the room-temperature egg whites, granulated sugar, cream of tartar, and a pinch of salt. Set the bowl over the simmering water, making sure it doesn’t touch the water below. Whisk constantly for about 4 to 5 minutes until the sugar has fully dissolved and the mixture reaches approximately 160°F (71°C). You can test this by rubbing a small amount between your fingers to confirm that it feels smooth and not gritty.
Step 3: Whip to Perfect Peaks
Transfer the hot mixture to your stand mixer bowl or a mixing bowl if using a hand mixer. Beat on high speed for 6 to 8 minutes until the frosting becomes thick, glossily shiny, and forms stiff peaks. You’ll know the frosting is ready when the bowl feels cool to the touch and the texture is light yet sturdy. This whipping step is key to achieving that cloudlike consistency.
Step 4: Flavor It Up
Add your pure vanilla extract along with any optional almond extract or lemon juice if desired. Beat the frosting for just another 30 seconds to evenly incorporate the flavors without deflating those beautiful peaks. This finishing touch gives the frosting its charming aroma and nuanced taste that pairs perfectly with any cupcake.
Step 5: Frost or Store
Use your Marshmallow Frosting for Cupcakes Recipe immediately by piping or spreading it onto cooled cupcakes. If you need to hold off, place the frosting in the refrigerator for up to 2 hours—but remember to whisk it again briefly before decorating to bring back that fluffy texture.
How to Serve Marshmallow Frosting for Cupcakes Recipe
Garnishes
Once your cupcakes are dressed with this luxurious marshmallow frosting, think about adding a garnish that complements without overshadowing. Toasted coconut flakes add a delightful crunch and a subtle toasty flavor. Fresh berries like raspberries or blueberries burst with juiciness next to the airy icing. Or sprinkle a little finely chopped nuts or edible glitter for a festive, sparkling finish that’s sure to impress.
Side Dishes
This marshmallow frosting pairs beautifully with a variety of cupcake flavors and simple sides. A warm cup of tea or hot cocoa is excellent alongside for a cozy treat. Fresh fruit salads with bright citrus or tropical fruits balance the sweetness wonderfully. Even a light scoop of tangy sorbet can refresh your palate when enjoying these fluffy delights.
Creative Ways to Present
Don’t be afraid to play around with presentation! Pipe the marshmallow frosting using a large star or round tip for elegant swirls or classic dollops. You can also torch the frosting slightly with a kitchen torch to create that signature toasted marshmallow effect, adding a bit of drama and smoky flavor. For special occasions, consider layering it between cupcake halves or turning cupcakes into mini ice cream sandwiches with frosting as the “glue.”
Make Ahead and Storage
Storing Leftovers
If you have leftover frosting, it’s best stored in an airtight container in the refrigerator for up to 2 days. Keep in mind, due to its fluffy and slightly delicate nature, it may lose some airiness over time and require a quick re-whip prior to use.
Freezing
Freezing marshmallow frosting is not highly recommended because the texture can change once thawed. However, if you need to, freeze in a tightly sealed container for up to one month. Thaw it overnight in the fridge and then whip it gently to revive some of the original fluffy texture before use.
Reheating
To gently bring your stored frosting back to spreading consistency, remove it from the fridge and let it come to room temperature. Then use a hand mixer on low speed to re-whip it. Avoid overheating to prevent the frosting from breaking down or becoming liquidy.
FAQs
Can I make Marshmallow Frosting for Cupcakes Recipe without raw eggs?
Since this recipe uses egg whites cooked over simmering water, the heat ensures the eggs are safe to consume. For those concerned about raw egg whites, this method actually cooks them gently. However, if you prefer to avoid eggs altogether, other frosting recipes like marshmallow fluff-based or buttercream might be better choices.
How long does marshmallow frosting stay fresh on cupcakes?
Once applied, marshmallow frosting is best enjoyed within a day at room temperature. If left out longer, it might start to weep or lose its structure. Refrigerating the cupcakes can extend freshness by a day or two, but allow them to come to room temperature before serving.
Can I add food coloring to this frosting?
Absolutely! Adding food coloring to the frosting after it has been whipped in Step 4 is the easiest way to achieve vibrant colors. Use gel or paste food coloring to avoid thinning the texture and beat it in gently until uniformly blended.
What if my frosting isn’t forming stiff peaks?
This usually means the sugar hasn’t fully dissolved or the mixture isn’t cool enough. Make sure to whisk the mixture over simmering water long enough until warm and smooth, and that your mixer is powerful enough. Also, room temperature egg whites whip better than cold.
Is it possible to make this frosting ahead of time?
Yes, but keep in mind that marshmallow frosting is best made fresh. If you need to prepare it ahead, refrigerate it for up to 2 hours and whisk again before using to restore fluffiness. Beyond that, the texture can degrade.

- 4 large egg whites (room temperature)
- 1 cup granulated sugar
- 1/4 teaspoon cream of tartar
- Pinch of salt
- 1 teaspoon pure vanilla extract
- Optional: 1/2 teaspoon almond extract
- Optional: 1/4 teaspoon lemon juice
Instructions
- Prepare Double Boiler: Fill a saucepan with 2 inches of water and bring it to a simmer. This will be used to gently heat the frosting mixture without direct heat.
- Combine Ingredients Over Simmering Water: In a heatproof bowl, combine the egg whites, granulated sugar, cream of tartar, and a pinch of salt. Place this bowl over the simmering water, ensuring the bottom does not touch the water. Whisk constantly for 4 to 5 minutes until the sugar dissolves completely and the mixture reaches 160°F (71°C). Test by rubbing a bit between your fingers to ensure it’s smooth without any sugar granules.
- Whip the Mixture: Transfer the warm mixture to a stand mixer bowl or use a hand mixer. Beat on high speed for 6 to 8 minutes until the frosting forms stiff, glossy peaks and the bowl feels cool to the touch.

Notes
- Ensure egg whites are at room temperature for better volume when whipping.
- The sugar must be fully dissolved to avoid a grainy texture in the frosting.
- Temperature control is crucial to prevent cooking the egg whites while dissolving the sugar.
- Use the frosting immediately for best results; refrigeration can stiffen it, so whisk again to revive.
- Optional extracts like almond or lemon can customize the flavor to your preference.
