Ingredients You’ll Need
Gathering your ingredients is a breeze, and each one plays a vital role in creating the luscious texture and sweet flavor this Marshmallow Frosting Recipe is known for.
- 4 large egg whites (room temperature): Using room temperature whites helps achieve maximum volume and stability in the frosting.
- 1 cup granulated sugar: This is the sweet base that will dissolve completely, giving the frosting its characteristic shine and smooth feel.
- 1/4 teaspoon cream of tartar: Helps stabilize the egg whites and keep those fluffy peaks intact.
- 1 teaspoon pure vanilla extract: Adds warmth and depth to the flavor.
- Pinch of salt: Balances the sweetness and enhances the overall taste.
- Optional 1/2 teaspoon almond extract: For a subtle nutty twist that complements the sweetness beautifully.
- Optional 1/4 teaspoon lemon juice: Adds a fresh brightness that cuts through the richness.
How to Make Marshmallow Frosting Recipe
Step 1: Set Up a Double Boiler
Fill a saucepan with about 2 inches of water and bring it to a gentle simmer. This creates the perfect gentle heat needed for slowly dissolving the sugar without scrambling the egg whites.
Step 2: Whisk Ingredients Over Heat
In a heatproof bowl, combine the egg whites, granulated sugar, cream of tartar, and a pinch of salt. Place the bowl over the simmering water, making sure it doesn’t touch the water. Whisk constantly for 4 to 5 minutes until the sugar is fully dissolved and the mixture reaches 160°F (71°C). You’ll know it’s ready when it feels silky smooth between your fingers without any graininess.
Step 3: Beat Until Glossy Peaks Form
Transfer the warm mixture to a stand mixer or use a hand mixer. Beat on high speed for 6 to 8 minutes, until stiff, glossy peaks appear and the bowl feels cool to the touch. This stage gives the frosting its classic fluffy, marshmallow-like texture.
Step 4: Add Flavors
Mix in the vanilla extract along with any optional flavorings like almond extract or lemon juice. Continue beating for another 30 seconds so everything blends perfectly and your frosting has that lovely fragrant aroma.
Step 5: Frost Immediately or Refrigerate
Once ready, use the frosting immediately by piping or spreading onto your cupcakes or cake. If you need to store it, place it in the refrigerator for up to 2 hours. Just whisk again briefly before using to bring back that creamy fluffiness.
How to Serve Marshmallow Frosting Recipe
Garnishes
This Marshmallow Frosting Recipe pairs wonderfully with a variety of garnishes to dress up your desserts. Sprinkle with toasted coconut flakes, a dusting of cocoa powder, or colorful sprinkles for a fun and festive look.
Side Dishes
Serve cupcakes or cakes topped with this frosting alongside fresh berries or a warm fruit compote. The natural tartness of the fruit beautifully balances the sweet, airy marshmallow topping.
Creative Ways to Present
Think beyond just spreading or piping—try swirling the frosting with a spatula to create soft peaks or torch the top lightly for a caramelized marshmallow effect. You can also add edible glitter or shape it into little marshmallow-style mounds for extra charm.
Make Ahead and Storage
Storing Leftovers
Should you have any leftover Marshmallow Frosting Recipe, store it in an airtight container in the refrigerator. It will keep well for up to 2 days. When ready to use, simply whisk it again to restore the light, fluffy texture.
Freezing
Freezing marshmallow frosting is generally not recommended because the delicate texture doesn’t always survive thawing well—it can become watery or separate. Fresh is best for this recipe to maintain that pillowy softness.
Reheating
If your frosting feels stiff after refrigeration, gently reheat it over a double boiler to soften before whisking back to fluffy perfection. Avoid microwaving to prevent cooking the egg whites unevenly.
FAQs
Is this Marshmallow Frosting Recipe safe to eat raw?
Yes! Since you heat the egg white mixture to 160°F while whisking over simmering water, this method effectively cooks the egg whites and makes the frosting safe to enjoy.
Can I use a hand mixer instead of a stand mixer?
Absolutely. A hand mixer works perfectly fine; it might take a little more time to reach stiff peaks compared to a stand mixer, but the results will be just as delightful.
How long will the frosting hold up on cupcakes?
This frosting holds its shape beautifully at room temperature for several hours, making it perfect for parties and events. If it’s particularly warm, refrigeration is advised to keep it stable.
Can I add food coloring to this Marshmallow Frosting Recipe?
Yes, gel or paste food coloring works best here. Add a small amount after beating the frosting to the glossy peak stage and fold gently to achieve vivid, streak-free color.
What should I do if the frosting looks grainy or won’t form peaks?
This usually means the sugar hasn’t fully dissolved or the mixture wasn’t heated enough. Return the bowl to the simmering water and whisk until smooth, then try beating again. Patience is key for that perfect texture!
