French Buttercream, or French Meringue Buttercream, is a go-to frosting in traditional French pastry. It's commonly used for classic treats like Christmas Yule logs and fancy desserts like entremets.

Unlike Swiss buttercream or Italian Buttercream, which is made with egg whites, French buttercream is made by whipping egg yolks and then pouring in hot sugar syrup and butter, giving it a richer taste and deeper color.

As a French pastry blogger, I must confess that this frosting isn't as popular in France as anywhere else in the world of cakes. However, its smooth and creamy texture makes it a choice of frosting for cake decoration and other pastries.

Ingredient you need

You need these ingredients to make French buttercream:

• Egg Yolks: Only egg yolks that can be replaced with whole eggs for a whiter cream.
• Sugar Syrup: A cooked sugar syrup made from powdered sugar and water.
• Butter: Unsalted butter softened to room temperature but not too soft.
• Vanilla and Salt: Pure vanilla extract or a vanilla bean and a pinch of salt.

>> Don't waste your egg whites: use them to make these egg white chocolate chip cookies, French meringue cookies or this Swiss meringue buttercream, marshmallow frosting.

How to make French Buttercream Frosting Recipe 

Here are some quick visual instructions. Don't forget that full instructions with exact ingredients can be found in the main recipe card below!

Step 1: Place the egg yolks in the mixing bowl of a stand mixer fitted with the whisk attachment and beat on medium speed until you get a frothy yolk mixture.

Step 2: Cook the sugar and water in a small saucepan over medium heat to make a sugar syrup. Monitor the temperature with a candy thermometer, which should read 115°C (239°F) (soft ball stage).

Step 3: Reduce mixer speed and drizzle the hot syrup in the bottom of the bowl over the egg mixture. Continue mixing at high speed for around 10 minutes, until cool and stiff peaks.

Step 4: Lower the mixer speed again and add softened butter, vanilla and salt. Continue on high speed for at least 10 minutes until smooth.

Storage instructions

Fridge: This buttercream can be stored under plastic wrap or in an airtight container in the fridge for up to 1 week. It is stable at room temperature for a few hours.

After chilling, it will harden like other meringue buttercreams, so you'll need to let it return to room temperature and whisk it again with a hand mixer to restore its supple, smooth texture.

In the freezer: It can be frozen for up to 3 months, let the frozen buttercream defrost overnight in the fridge before bringing to room temperature and whipping again.

Recipe Questions & Troubleshooting

Can I use whole eggs instead of just egg yolks?

Most French buttercream recipes are traditionally made with egg yolks, but it's possible to make it using egg whites if desired.

Is French buttercream safe to eat since it contains raw egg yolks?

The sugar syrup, when added to the egg yolks in French buttercream, typically cooks and pasteurizes the yolks, making the buttercream stable and safe to eat. (you can also cook the eggs in a double boiler to 160°C before whipping them)

Why does my French buttercream look curdled or separated?

French buttercream can appear curdled or separated if the temperature of the butter and egg yolk mixture is imbalanced. Simply continue to mix the frosting until it becomes homogeneous and smooth.

Is French buttercream stable?

Yes, French buttercream is stable and holds its shape well for decorating cakes and pastries.

How do I fix French buttercream that's too runny or too stiff?

If it's too runny, chill it briefly, then re-whip; if it's too stiff, warm a small portion, incorporate it back, and re-whip.

Can I make French buttercream in advance?

Yes, you can make French buttercream in advance and store it in the refrigerator or freezer; re-whip it before using.
