Swiss Meringue Buttercream

Swiss Meringue Buttercream is a light, silky, and incredibly smooth frosting made from egg whites, sugar, and butter. Unlike American buttercream, which is made simply by creaming butter and powdered sugar, Swiss Meringue Buttercream involves heating the egg whites and sugar together before whipping them into a soft, glossy meringue and then adding butter. This results in a frosting that is less sweet, more stable, and luxuriously airy. It spreads beautifully, pipes like a dream, and holds its shape without feeling heavy or greasy.

Because of its refined texture and mild sweetness, this buttercream is a favorite for wedding cakes, cupcakes, celebration pastries, and any dessert that needs a smooth and professional finish. While it may seem a bit more involved than other frostings, the results are absolutely worth it. Once you learn the method, it becomes surprisingly easy and repeatable.

Ingredients for Swiss Meringue Buttercream

Here’s everything you’ll need to make this Swiss Meringue Buttercream

• 5 large egg whites
• 1 ½ cups granulated sugar
• 2 cups (4 sticks) unsalted butter, room temperature and cut into small cubes
• 2 teaspoons pure vanilla extract or flavoring of your choice
• Pinch of salt

How to Make Swiss Meringue Buttercream

Step One

First, prepare your double boiler: Fill a medium saucepan with 1-2 inches of water and bring it to a simmer. Place a heatproof mixing bowl over the saucepan, ensuring the bottom of the bowl doesn’t touch the water. This will gently heat the egg whites without cooking them.

Step Two

Now: Heat the egg whites and sugar. Add the egg whites and granulated sugar to the bowl. Whisk continuously until the sugar is completely dissolved and the mixture is warm to the touch about 160°F if using a thermometer. You shouldn’t see or feel any sugar granules when you rub the mixture between your fingers. This step also makes the mixture safe to eat.

Step Three

To whip the meringue: Transfer the warm egg white mixture to a stand mixer fitted with the whisk attachment. Begin whipping on medium high speed until the mixture is thick, glossy, and forms stiff peaks. This may take 8 to 10 minutes. The bowl should be cool to the touch before proceeding.

Step Four

Then, add the butter. Turn on the mixer to the paddle attachment. Add the butter in small cubes at a time while the mixer is running on medium speed. The mixture may appear lumpy or slightly separated at times; continue mixing until you achieve a smooth, creamy buttercream consistency.

Step Five

Finally, add the flavoring and finishing touch. Stir in the vanilla extract and a pinch of salt. Beat for another minute until the mixture is smooth, silky, and spreadable. Your Swiss buttercream is now ready.

Tips for Making the Best Swiss Meringue Buttercream

Ensure the mixing bowl is completely clean and free of grease. Any oil can prevent the meringue from whipping.

If the buttercream becomes too soupy, refrigerate it for 10 minutes, then beat again.

If the buttercream looks lumpy or broken, keep mixing it almost always comes together.

Always let the meringue cool before adding butter. Warm meringue melts butter.

Serving Suggestion

I like to serve it with many drinks, including hot and cold ones. For example, sometimes I serve it with tea, coffee, or hot cocoa, and sometimes with fresh fruit juice or a mojito.
