    What Is Swiss Meringue Buttercream?

    Most people know traditional American buttercream as the very sweet frosting you make by combining confectioners' sugar and butter.

    Unlike an American buttercream, the base of a Swiss meringue buttercream recipe does not use powdered sugar.

    To make it, heat egg whites and granulated sugar over a double boiler using the Swiss meringue technique—this dissolves the sugar and makes the egg whites food-safe. Then whip the mixture into a fluffy meringue and gradually mix in softened butter. It's one of the most perfect frostings imaginable.

    Simply put, it's a mouthwatering buttercream frosting that is silky smooth and not too sweet. It pipes and spreads like a dream, and can be colored with food coloring.

    Italian vs Swiss Meringue Buttercream

    Like its Swiss cousin, Italian meringue buttercream combines sweetened meringue and butter. However, you prepare the base of an Italian meringue using a slightly different cooking method.

    For Italian meringue, cook sugar and water together to a specific temperature stage on a candy thermometer. Then drizzle the hot syrup into whipping egg whites to form a fluffy meringue. Once whipped, gradually mix in softened butter to create a creamy, not-too-sweet buttercream.

    The finished frosting will be stiffer and slightly more stable than Swiss meringue buttercream.

    You can enjoy both Swiss and Italian meringues (without the butter) straight from the bowl or bake them slowly to make crisp meringue desserts.

    Ingredients for Swiss meringue buttercream including egg whites, sugar, butter, and vanilla.

    Ingredients

    Check out these ingredient tips as you gather everything you'll need. See recipe card for quantities.

    • Egg whites: The Swiss meringue frosting starts with — you guessed it! — egg whites. Use the whites from large eggs (not medium or extra large) for the base of the buttercream.
    • Granulated sugar: The second half of the meringue! You'll need granulated sugar for sweetness. It also has a stabilizing effect on the egg whites.
    • Unsalted butter: Mix pure, sweet, unsalted butter into the meringue to create a melt-in-your-mouth texture with a balanced flavor—not too sweet or salty. Let the butter come close to room temperature before adding it to the frosting.
    • Vanilla extract: For added flavor, I always mix pure vanilla extract into my Swiss meringue buttercream frosting. You could also flavor it with almond, lemon, or any other flavoring you enjoy.

    How to make Swiss meringue buttercream

    Below is an overview of how to make a Swiss meringue buttercream recipe. See the recipe card below for the full instructions.

    1. Prepare ingredients: Soften butter, then bring a saucepan of water to a boil over medium-high heat; reduce to a simmer. Combine 5 large egg whites and 1¼ cups sugar in a heatproof bowl.
    2. Place bowl over saucepan: Set the bowl over the pan of simmering water and whisk constantly.
    3. Whisk: Whisk continuously until the sugar dissolves and no crystals remain, about 5 minutes. Remove from heat.
    4. Whip to stiff peaks: Use a mixer fitted with a whisk attachment to whip the sugar mixture on high until it is cool and has formed stiff peaks, 10 to 12 minutes.
    5. Beat in butter: Reduce speed to medium-high and begin beating in 4 sticks (2 cups) softened butter, a little at a time.
    6. Add flavoring: The buttercream will look a little curdled after adding the butter. Turn mixer to low, add 1 teaspoon vanilla extract, and resume mixing.
    7. Continue mixing until creamy: Mix slowly to release air bubbles and fully incorporate the butter, 3 to 5 minutes. It should look smooth and creamy. Use immediately or refrigerate.

    Tara's expert tips

    Want to make the perfect Swiss meringue buttercream recipe? Take a peek at these expert tips to avoid common mistakes.

    • Check for sugar crystals: When making the meringue, it's important for the sugar to fully dissolve into the egg whites. You can test the mixture for remaining sugar crystals by rubbing a small amount between your fingers--it should feel smooth without any grittiness. Keep heating and whisking the meringue until it feels right before proceeding with the rest of the recipe.
    • Whip to stiff peaks: When whipping the meringue, it will go through a series of phases. You're looking for a phase called stiff/firm peaks where the mixture has thickened sufficiently to hold its shape. You can test the meringue by lifting the whisk out of the mixture. Look into the bowl where the whisk was and watch for how the meringue reacts. As it thickens, the mixture should pull upward toward the whisk. The tops of these peaks may curl over (soft peaks) or stick upward (firm peaks). Keep whipping until the you get stiff peaks that point upward.
    • Use softened butter: Swiss buttercream should be smooth and creamy. Using softened butter will make the mixing process painless and helps to prevent lumps. To soften butter, allow it to sit on the counter for approximately 30 minutes. You'll know it is ready to use when you can press the outside wrapping gently with your thumb and leave a slight indent.
    • Keep whipping: As you whip the buttercream, it goes through several stages. You’ll notice it looks lumpy and curdled during the mixing process—but don’t worry, that’s totally normal! Just keep whipping on medium or low speed. The gentle mixing brings everything together into a smooth, creamy frosting.
    • Room temperature is best: Although refrigeration is best for storage, Swiss meringue buttercream is easiest to use and tastiest to eat at room temperature. Let it sit for a bit and allow desserts to come to room temperature before serving.

    How to color buttercream frosting

    To get those gorgeous, deep shades, it's important to follow a couple of food coloring guidelines.

    • Food coloring: Add food coloring once you’ve fully combined the buttercream—mixing it in at the end helps the color set evenly.
    • Don't use traditional liquid food coloring: Mixing liquid food coloring into your frosting will likely ruin it. To get nice shades, you'll have to add so much liquid food coloring that the buttercream will get runny.
    • Use gel paste food coloring: Gel coloring is my favorite; it's super intense and doesn’t add excess liquid to the frosting. You’ll notice that with intense colors like red and black, or deep colors like blue and dark green, you’ll still need to add a lot of gel coloring. Thankfully, the gel won't ruin the consistency of the frosting.
    • Plan ahead: You can expect the color of your frosting to almost double in intensity after sitting at room temperature for about 24 hours. I recommend making and coloring your frosting a day in advance of your baking project so that the coloring has time to set and deepen.

    Tara's coloring tips

    Swiss meringue buttercream doesn't color the same as American buttercream. Here are a few things I've learned over the years.

    • Color an intense base color first: I color about ¼ cup of buttercream in a small bowl, using gel coloring. It acts as a concentrate, so I make it very intense. Then I can add a little at a time to a bigger portion of buttercream knowing I won't ruin the whole batch with the wrong color!
    • Dark colors need heat: As mentioned above, dark colors are harder to achieve with this buttercream. I melt, yes melt! a few tablespoons of buttercream in a bowl and add the rich colors. The melted base is even more concentrated than the base color described above. You can stir the melted buttercream into non-melted buttercream to intensify the color.

    Recipes using Swiss meringue buttercream

    I would make what seemed like vats of this when I worked at Martha Stewart magazine! I used it on cupcakes, holiday and spring cakes, and all the cute decorated kids' cupcakes in the Kids magazine. Here are a few ideas for how you can use this recipe at home:

    • Swirl: It's really lovely swirled in bright colors on top of delicious cupcakes like these Vanilla Birthday Cupcakes.
    • Pipe: It's also amazing for piping beautiful designs like the flowers on my Spring Flower Cupcakes! If you are new to piping buttercream, you'll want to get a standard set of piping tips, and disposable piping bags for easy cleanup!
    • Color: You'll notice that Swiss meringue buttercream tints easily with highly-concentrated gel paste food coloring, allowing you to make gorgeous shades of colored frosting that really shine. Check out my Party Rainbow Cake to see what I mean!

    Equipment

    You won't need a lot of fancy kitchen tools to make a bakery-style Swiss meringue buttercream recipe. Here's what I'd recommend having on hand:

    • Saucepan for simmering
    • Mixer with metal bowl
    • Ateco piping tip set
    • Gel paste food coloring set

    Storing and freezing instructions

    Keep your buttercream nice and fresh with proper storage!

    • Room temperature: Cover freshly made buttercream and keep it at room temperature for up to 24 hours, or refrigerate it right away.
    • Refrigerate: After 24 hours, transfer your buttercream to the fridge—it will stay fresh, covered, for up to two weeks.
    • Re-whip: After sitting at room temperature or in the refrigerator, air bubbles will begin to form. To restore the buttercream to it's satiny texture, you'll want to re-whip it on low speed until smooth again.
    • Freeze: Place Swiss meringue buttercream in a freezer-safe container and store it in the freezer for up to 3 months.Thaw refrigerated buttercream at room temperature before using. Then gently whip it at low speed to get it smooth and ready to use.
    • Quick-thaw: When I’m in a hurry, I don’t always have time to wait for frozen buttercream to thaw on the counter. To quick-thaw the frosting, zap it in the microwave for a few seconds at a time, until it's soft enough to put in a mixer, but don't melt it! Then re-whip as directed above with the mixer on low speed until all the cold lumps have thawed and smooth out.

    FAQ

    What are the disadvantages of Swiss meringue buttercream?

    There really aren't a lot of downsides to using Swiss buttercream! It doesn’t work well for frosting cookies you plan to stack. Swiss meringue buttercream will not form a hard outer crust and will stick to other cookies if stacked one on top of the other.

    What frosting do professional bakers use?

    Professional bakers use all kinds of frosting recipes depending on the desserts they are making.
    For example, they might use a royal icing for designing flooded sugar cookies or an American buttercream for stackable cookies, bars, and brownies.
    Cream cheese frosting is a go-to for desserts like red velvet and carrot cake, and icing makes an excellent topping for Bundt cakes and coffee cakes.
    Bakers often use Swiss meringue and Italian meringue buttercream for cake decorating and piping intricate details.

    Will a Swiss meringue buttercream recipe harden in the fridge?

    Yes, it will firm up in the fridge, but it doesn't form a hard crust on the outside the way that American Buttercream does. For the best taste and texture, serve baked goods topped with Swiss meringue buttercream at room temperature so that the frosting is soft and creamy.

    Is Swiss meringue buttercream food-safe?

    The egg whites and sugar mixture is food-safe and free from harmful bacteria at 160ºF. You can check the mixture with a thermometer to be sure. When I do the touch test—rubbing the mixture between my fingers to check for sugar crystals—I usually find that the sugar has dissolved right as the temperature hits around 160ºF.

    Ingredients
      

    • 5 large egg whites
    • 1¼ cups granulated sugar
    • 4 sticks (2 cups) unsalted butter (softened)
    • 1 teaspoon vanilla extract (or other flavoring extract)

    Instructions
     

    • Place a saucepan of water on the stove over high heat and bring to a boil. Reduce heat and let water simmer.
    • Whisk together 5 large egg whites and 1¼ cups sugar in a heatproof electric mixer bowl. Place the bowl over the pan of simmering water and whisk until sugar dissolves completely, about 5 minutes.
      Test for doneness by rubbing the mixture between your fingers--you shouldn't feel any sugar crystals.
    • Remove mixer bowl from heat and transfer to the mixer stand fitted with the whisk attachment. Beat on high speed until mixture cools and stiff peaks form, 10 to 12 minutes.
    • Reduce speed to medium-high and begin adding unsalted, softened butter a little at a time until just incorporated.
    • Turn mixer down to low speed, add vanilla extract, and continue mixing until smooth. Buttercream may curdle but will smooth out as you continue to beat it.
    • Use immediately, or cover and refrigerate for up to 2 weeks. Can also be frozen in a freezer-safe container for up to 3 months. Before using, bring to room temperature and beat on low until smooth.

    Notes

    Nutritional analysis is per 1 cup of buttercream. 
    See post for more detailed tips.
    Storing tips:
    • Room temp: Keep covered for up to 24 hours.
    • Refrigerate: Store in the fridge for up to 2 weeks.
    • Re-whip: Bring to room temp and mix on low to smooth out air bubbles.
     
    Coloring tips: 
    • Add color last: Always mix food coloring in after the buttercream is fully made for even color.
    • Avoid liquid food coloring: It can make your frosting runny.
    • Use gel paste: It gives intense color without changing the texture—even for tricky shades like red or black.
    • Plan ahead: Colors deepen over time. Let frosting sit for 24 hours for the best results.

        Hi Becci! I mention gel paste food coloring (like Americolor) in the post. It's my favorite. It's intense and doesn't add liquid to a frosting. I add food coloring once my frosting is finished being made. You'll notice with colors like red, or black, deep colors like blue or dark green, that you'll need a massive amount of coloring. Do plan ahead! The colors intensify quite a bit in the frosting if left at room temperature for a day. The rainbow colors you see in the images were left overnight, then re-stirred and placed in the piping bags. The color almost doubles in intensity.

        Hi Michelle,
        I haven't ever used monk fruit sugar in this recipe but my familiarity with it would suggest it's not a good substitute.
        I think you need the chemical makeup of sugar to create the meringue. That being said, you could try a 1/2 or 1/4 of a batch to test it.
        That way you can see if you like the flavor as well.
