Ingredients You’ll Need
This Marshmallow Frosting Recipe calls for a handful of simple, pantry-friendly ingredients that come together to create a fluffy, stable frosting. Each one plays a vital role: from sweetness to stability and flavor—the magic is in the mix!
- Granulated sugar: Provides the perfect balance of sweetness and helps create the syrup base essential for structure.
- Light corn syrup: Adds body and prevents crystallization, keeping your frosting smooth and glossy.
- Egg whites: These are the heart of the frosting, whipped into voluminous peaks that give it lightness.
- Cream of tartar: Helps stabilize the egg whites for a firmer, longer-lasting frosting.
- Table salt: A pinch to enhance all the other flavors and balance the sweetness.
- Vanilla extract: Infuses the frosting with a warm, comforting aroma and depth of flavor.
How to Make Marshmallow Frosting Recipe
Step 1: Prepare Your Double Boiler and Mixing Tools
First, set up a double boiler by filling a saucepan with 1 to 2 inches of water and bringing it to a gentle simmer. Place a clean, dry, grease-free bowl—ideally a stainless steel mixing bowl—on top, making sure it doesn’t touch the water. This setup gently heats the ingredients without scrambling the eggs.
Step 2: Combine Your Ingredients
In your chosen bowl, whisk together the granulated sugar, light corn syrup, egg whites, cream of tartar, and salt until everything is nicely blended. This mixture forms the base that will become your luscious marshmallow frosting.
Step 3: Heat and Dissolve the Sugar Mixture
Place the bowl over the simmering water, and whisk constantly. This is crucial because you want the sugar to completely dissolve and the mixture to reach 160°F (70°C). This ensures the eggs are safe to eat and that your frosting will have that flawless, silky texture without any grit.
Step 4: Whip to Fluffy Perfection
Remove the bowl from heat and attach it to your stand mixer fitted with a whisk attachment. Start mixing on low and gradually increase to high speed. Beat for 5 to 10 minutes, until the frosting is thick, billowy, and glossy with stiff peaks that hold their shape beautifully.
Step 5: Add the Flavor
Once your frosting is whipped to perfection, stir in the vanilla extract for an inviting scent and that classic marshmallow flavor. Your Marshmallow Frosting Recipe is now ready to use—or store carefully until your dessert is ready for decorating.
How to Serve Marshmallow Frosting Recipe
Garnishes
To make your marshmallow frosting even more tempting, try adding a toasted sprinkle of chopped nuts, rainbow sprinkles, or a drizzle of melted chocolate on top. For a special touch, a quick pass with a culinary torch can give it a lightly caramelized exterior that’s as gorgeous as it is delicious.
Side Dishes
Marshmallow frosting pairs beautifully with freshly baked goods like classic chocolate or vanilla cupcakes, rich brownies, and even simple slices of pound cake. It also complements seasonal fruits like ripe strawberries or grilled peaches when served alongside for a balanced bite of sweet and fresh.
Creative Ways to Present
Try piping this frosting into whimsical shapes, from soft swirls to rosettes, for an eye-catching finish. You can even use it as a filling for layer cakes or sandwich it between two cookies for delectable homemade s’mores-inspired treats. The fluffy texture lends itself to endless decorating ideas!
Make Ahead and Storage
Storing Leftovers
If you have leftover marshmallow frosting, no worries! Store it tightly covered at room temperature. It might need a quick re-whip with your mixer before using, especially if it’s been sitting for several hours to bring back that soft, pillowy texture.
Freezing
This frosting doesn’t freeze particularly well because its light and airy texture can deflate or become watery once thawed. It’s best to enjoy it fresh or stored at room temperature for short periods.
Reheating
Since this frosting is best enjoyed at room temperature, simply giving it a few gentle beats with your mixer can revive the fluffiness if it settles. Avoid direct heat to reheat, as this can melt the delicate structure of the marshmallow frosting and change its texture.
FAQs
Can I use pasteurized egg whites for this frosting?
Absolutely! Pasteurized egg whites are a safe and convenient choice, especially if you want to avoid any raw egg concerns. Just be sure they are at room temperature before starting to help with whipping up those stiff peaks.
How long does marshmallow frosting last once made?
When stored properly at room temperature in an airtight container, this frosting stays fresh for up to 24 hours. Beyond that, it may start losing its fluffy structure and require re-whipping for best texture.
Can I flavor the frosting other than vanilla?
Definitely! While vanilla is classic, you can experiment by adding almond extract, peppermint extract, or even a splash of citrus zest for a custom twist. Just add these after whipping, like the vanilla extract.
Is there a way to make this frosting vegan?
Traditional marshmallow frosting relies heavily on egg whites, so it’s challenging to achieve the same texture vegan-wise. However, aquafaba—chickpea brine—can sometimes act as a substitute; just be aware the technique and outcome may vary.
Can I use this frosting for piping decorations?
Yes! This frosting whips to stiff peaks that hold their shape beautifully, making it excellent for piping decorations such as borders, rosettes, or other intricate designs on cakes and cupcakes.
Final Thoughts
Making your own Marshmallow Frosting Recipe is such a rewarding experience, and once you’ve tasted the light, fluffy sweetness, you’ll never want to go back to store-bought frosting. It’s a versatile, show-stopping addition to so many desserts, and with just a handful of simple ingredients, you can transform your baking into something truly memorable.

Marshmallow Frosting Recipe
This Marshmallow Frosting recipe delivers a light, fluffy, and glossy frosting perfect for cakes and cupcakes. Made by whisking egg whites with sugar and corn syrup over a double boiler, then whipping to stiff peaks with a touch of vanilla, it provides a smooth, sweet, and stable frosting that can be toasted for added flavor and texture.
- Total Time: 35 minutes
- Yield: 8 servings
Ingredients
Marshmallow Frosting Ingredients
- ¾ cup granulated sugar
- ⅔ cup light corn syrup
- 4 large egg whites (room temperature preferred)
- ½ teaspoon cream of tartar
- ⅛ teaspoon table salt
- 1 ½ teaspoons vanilla extract
Instructions
- Prepare Double Boiler: Set up a double boiler using a stainless steel mixing bowl and a medium saucepan filled with 1-2 inches of water. The bowl should sit above the water without touching it. Ensure the bowl is clean, dry, and grease-free to prevent the egg whites from deflating.
- Combine Ingredients: In the mixing bowl, whisk together sugar, light corn syrup, egg whites, cream of tartar, and salt until thoroughly combined.
- Heat Mixture: Place the bowl over the simmering water on medium-low heat. Continuously whisk the mixture to dissolve the sugar and cook the egg whites until the temperature reaches at least 160°F (70°C). The mixture should feel smooth and not gritty when rubbed between fingers, indicating complete sugar dissolution.
- Whip to Stiff Peaks: Remove the bowl from the heat and attach it to a stand mixer fitted with a whisk attachment. Gradually increase the mixer speed to high and whip for 5-10 minutes until the frosting forms thick, billowy, glossy stiff peaks.
- Add Vanilla Extract: Fold in the vanilla extract and mix until fully incorporated for enhanced flavor.
- Use or Store: Use the marshmallow frosting immediately for best results. Alternatively, cover it tightly and store at room temperature. If stored for several hours, re-whip before use. For a decorative touch, toast the frosting with a culinary torch after piping onto baked goods.
Notes
- Room temperature egg whites whip better and create more volume.
- Ensure no grease or moisture is in the bowl or on utensils to help the egg whites whip properly.
- The sugar must fully dissolve to avoid gritty frosting.
- Leftover egg yolks can be used in other recipes to avoid waste.
- The frosting can be toasted with a culinary torch for a toasted marshmallow flavor.
- Store at room temperature and re-whip if it sits for more than a few hours before using.
