What Is the Difference Between Swiss Meringue Buttercream and Buttercream?

In its simplest form, buttercream is a mixture of butter and sugar that’s been beaten together into a fluffy whipped frosting.

This is what people generally think of when they imagine iced cakes or filled pastries. It may also be referred to as American buttercream.

Swiss meringue buttercream is the type of frosting that’s most often found in professional kitchens. Sometimes simply known as Swiss buttercream, it involves a double boiler, eggs, and is a bit more difficult to make than its American counterpart. But still, something that you can make at home.

It’s all about heating egg whites and sugar in a double boiler to make a smooth meringue and then it’s beaten with butter.

What Is the Difference Between Italian and Swiss Meringue Buttercream?

Italian buttercream is yet another variety of this frosting. It’s very stable and the difference comes down to the method of making the frosting as well as the temperature of the sugar mixture.

For Swiss the egg whites and sugar are heated and whisked to about 160 degrees together, then whipped to perfection in an electric mixer. The butter is then added to the thicker egg whites.

Does Swiss Meringue Buttercream Harden?

While Swiss meringue buttercream will eventually harden, it can be left at room temperature for about 8 hours. When spread on a cake, it will take over two days to lose its texture.

However, if you want your frosting to harden, that’s totally alright! Simply place it in the fridge in an airtight container for a couple of days. This will make it a bit denser than it would be if you ate it straight from the mixer.

What Does Swiss Meringue Buttercream Taste Like?

American buttercream is by far the sweetest type of buttercream. Since this is what you’re likely most familiar with, think of Swiss buttercream as less sweet, creamier, and lighter in texture. The flavor and texture are still full and luxurious. It’s like a light whipped cream but with a buttercream frosting flavor.

Is Swiss Buttercream Good for Piping?

Like all buttercream varieties, Swiss buttercream is great for piping. You can create accents, patterns, designs, and words by naturally dyeing your frosting and piping it over another color.

Can You Overbeat Swiss Meringue Buttercream?

Swiss meringue buttercream can be overbeaten. Once the frosting is silky and smooth, stop mixing so you can keep the soft, luxirous texture. If you’re going to use it for piping you can beat it until it’s a little more firm.

Ingredients

  • 1 cup grandulated sugar
  • 4 large egg whites
  • 1 1/2 cups unsalted butter, room temperature
  • 1 tsp vanilla extract

Instructions

  • Fit the bowl over a pan of simmering water.
  • Add the sugar and the egg whites into a heatproof mixing bowl.
  • Whisk constantly until the mixture is hot, sugar is dissolved and the egg whites are a little frothy. About 5 minutes. It should look like shiny marshmallow cream. This step is very important and you can use a thermometer to check the temperature. It should get to 160 degrees.
  • With the whisk attachment, transfer the egg mixture to a mixing bowl and beat on medium speed until cooled and thicker for about 5 minutes.
  • Add in one stick of room temperature butter at a time, beating until smooth.
  • On low speed, add in the extract.
  • If the buttercream curdles or separates, just keep beating on high until it comes back together. You should end up with a shiny, smooth, and absolutely delicious buttercream frosting!

Notes

To change the flavor add in different extracts! 
Use a candy thermometer to check the temperature of the egg and sugar mixture.
