From Start to Finish: Swiss Meringue Buttercream Recipe

Step 1: Prepare the Meringue
Start by bringing a pot of water to a simmer. In a heatproof bowl, combine the 7 large egg whites and 2 cups of granulated sugar. Place the bowl over the simmering water, ensuring the bottom of the bowl does not touch the water. Whisk continuously until the sugar has dissolved and the mixture is warm to the touch, about 3-5 minutes.
Step 2: Whip the Meringue
Transfer the bowl to your stand mixer fitted with the whisk attachment. Beat the mixture on medium speed until soft peaks form. Gradually increase to high speed and continue whipping until stiff peaks form and the meringue is glossy and smooth, about 10 minutes. The bowl should feel cool to the touch when done.
Step 3: Add the Butter
Reduce the mixer speed to low and add the 1 1/2 cups of softened unsalted butter, one tablespoon at a time. Once all the butter is incorporated, increase the speed to medium and continue mixing until the buttercream is smooth and creamy.
Step 4: Flavor It Up
Add the 2 tsp of vanilla extract and 1/4 tsp of fine sea salt to the buttercream. Mix until fully combined. Taste and adjust the flavor if necessary.
Step 5: Use or Store
Your Swiss Meringue Buttercream is now ready to be used! You can pipe it onto cupcakes, spread it on cakes, or store it in an airtight container in the fridge for up to a week. When ready to use, re-whip the buttercream to restore its texture.
Holiday-Friendly Variations

- Chocolate Swiss Meringue Buttercream: Melt 4 oz. of semisweet chocolate and fold it into your buttercream for a rich chocolate flavor.
- Mint Swiss Meringue Buttercream: Add 1 tsp of peppermint extract for a refreshing minty twist.
- Fruit-Flavored Swiss Meringue Buttercream: Use pureed fruit or fruit extracts to flavor your buttercream.
- Spiced Pumpkin Swiss Meringue Buttercream: Mix in 1/2 cup of pumpkin puree and 1 tsp of pumpkin pie spice for a seasonal treat.
What I Learned Testing
Making Swiss Meringue Buttercream was an enlightening experience. I discovered that the key to a perfect meringue is patience—whipping the egg whites slowly allows them to incorporate air effectively. I also learned that temperature is crucial; the butter should be softened but not melted, as melted butter can lead to a greasy texture. Lastly, don’t skip the step of cooling the meringue before adding the butter; this prevents the butter from melting and ensures a fluffy consistency.
Save It for Later
If you’re not using your Swiss Meringue Buttercream right away, store it in an airtight container in the refrigerator for up to one week. When you’re ready to use it, simply take it out, let it come to room temperature, and re-whip it until it’s fluffy again. This makes it perfect for prepping ahead for parties or special occasions!
Handy Q&A
Can I use egg whites from a carton instead of fresh eggs?
Yes, you can use pasteurized egg whites from a carton. Just make sure to use the equivalent amount as stated in the recipe (7 oz). However, fresh egg whites often yield a better meringue texture.
Why is my Swiss Meringue Buttercream grainy?
If your buttercream is grainy, it could be due to the sugar not dissolving completely in the egg whites. Ensure you whisk the mixture until the sugar is fully dissolved and the meringue is smooth before adding the butter.
How do I color my Swiss Meringue Buttercream?
You can use gel food coloring to tint your buttercream. Start with a small amount and add more until you reach your desired shade. Gel colors work best because they don’t alter the texture of the frosting.
Can I freeze Swiss Meringue Buttercream?
Absolutely! Swiss Meringue Buttercream can be frozen for up to three months. Just thaw it in the refrigerator when you’re ready to use it, then re-whip to restore the texture.
