Swiss meringue buttercream frosting is a luxurious and silky-smooth topping that adds a touch of elegance to any cake or dessert. Unlike traditional American buttercream, which is made with powdered sugar and butter, Swiss meringue buttercream is created by combining egg whites and granulated sugar before incorporating softened unsalted butter.

1. How to Make Swiss Meringue Buttercream

To make Swiss meringue buttercream, start by whisking together fresh egg whites and granulated sugar in a heatproof bowl. Place the bowl over a pot of simmering water, making sure the bottom doesn’t touch the water. Continuously whisk the mixture until it reaches 160°F (71°C) to ensure that any potential bacteria in the raw eggs are safely pasteurized.

2. Achieving the Right Consistency

Once heated, transfer the mixture to a stand mixer fitted with a whisk attachment or use an electric hand mixer. Beat on medium-high speed until stiff peaks form and the bowl feels cool to touch. This process creates an airy meringue base for your frosting.

Add room temperature unsalted butter gradually, one tablespoon at a time while beating on medium speed until fully incorporated into the meringue mixture. It’s important that both your meringue and butter are at similar temperatures; otherwise, you might end up with curdled frosting.

3. Flavor Variations

Swiss meringue buttercream provides an excellent canvas for incorporating various flavors into your frosting creations. You can add vanilla extract for classic vanilla flavor or experiment with other extracts like almond or lemon for unique twists.

If you’re feeling adventurous, try incorporating melted chocolate, fruit purees, or espresso powder to infuse your buttercream with rich and decadent flavors. The possibilities are endless, allowing you to customize the frosting to complement your cake or dessert.

4. Tips for Working with Swiss Meringue Buttercream

When working with Swiss meringue buttercream, it’s essential to keep a few tips in mind:

  1. Room Temperature: Ensure that both the egg whites and butter are at room temperature before starting. This helps achieve a smooth and stable frosting.
  2. Sifting: Sift your powdered sugar before adding it to the meringue mixture to prevent lumps in the final product.
  3. Frosting Consistency: If your buttercream is too soft, refrigerate it for a short time until it firms up slightly before using. If it’s too stiff, place the bowl over warm water briefly and re-whip until desired consistency is reached.
  4. Storage: Swiss meringue buttercream can be stored in an airtight container in the refrigerator for up to a week or frozen for several months. Bring it back to room temperature and re-whip before using again.

Become familiar with these basics of Swiss meringue buttercream frosting, and you’ll be well on your way to creating delectable cakes adorned with velvety-smooth toppings that will impress family and friends alike!

Swiss meringue buttercream frosting is a velvety and luxurious icing that is perfect for cakes, cupcakes, and other delicious treats. To create this delectable frosting, it’s important to understand the key ingredients that make it so unique and delightful.

Egg Whites

The foundation of Swiss meringue buttercream is made from egg whites. They provide structure, stability, and a light texture to the frosting. It’s crucial to use fresh eggs at room temperature for the best results.


Sugar plays a significant role in both the flavor and texture of Swiss meringue buttercream frosting. It sweetens the mixture while also stabilizing the egg whites as they are whipped into a glossy meringue.


Butter is what gives Swiss meringue buttercream its rich and creamy consistency. It should be unsalted and softened to room temperature before being added gradually to the whipped egg white mixture.


A pinch of salt helps balance out the sweetness of the sugar in Swiss meringue buttercream frosting. It enhances all of its flavors without overpowering them.

Vanilla Extract or Flavorings

To add depth and complexity to your Swiss meringue buttercream, you can incorporate vanilla extract or other flavorings like almond or lemon extract. These extracts infuse their distinct aromas into the frosting, making it even more enticing.

Cream of Tartar (optional)

In some recipes, cream of tartar may be included when whipping up your egg whites for added stability during whisking. It’s not always necessary, but it can be useful if you’re experiencing difficulty achieving stiff peaks.

Food Coloring (optional)

If you want to add a pop of color to your Swiss meringue buttercream frosting, food coloring can be incorporated. However, make sure to use gel or powder-based colors instead of liquid ones to prevent altering the consistency of the frosting.

Understanding the essential ingredients for Swiss meringue buttercream frosting is crucial for achieving the perfect texture and flavor. By using fresh egg whites, sugar, butter, salt, vanilla extract or other flavorings, and optional ingredients like cream of tartar and food coloring, you’ll be able to create a delectable and visually appealing frosting that will elevate any baked creation.
