Ingredients

• 200 grams Granulated sugar
• 60 milliliters Water
• 4 large Egg yolks
• 250 grams Unsalted butter (softened, cut into cubes)
• 1 teaspoon Vanilla extract
• 1 pinch Salt

Directions

Step 1

In a medium saucepan, combine the granulated sugar and water over medium heat. Stir gently until the sugar dissolves completely, then bring the mixture to a boil without stirring further.

Step 2

Using a candy thermometer, monitor the temperature of the sugar syrup. Once it reaches 115°C (240°F), remove it from the heat immediately.

Step 3

While the sugar syrup is cooking, place the egg yolks in the bowl of a stand mixer fitted with the whisk attachment. Beat on medium-high speed until they thicken and turn pale, about 3-4 minutes.

Step 4

With the mixer running on medium speed, slowly pour the hot sugar syrup into the whipped egg yolks in a thin, steady stream. Be careful to pour the syrup down the side of the bowl to avoid splattering.

Step 5

Once all the sugar syrup has been added, increase the mixer speed to high and continue beating until the mixture cools to room temperature. This can take around 8-10 minutes.

Step 6

Reduce the mixer speed to medium and begin adding the softened butter, a few cubes at a time, waiting until each addition is incorporated before adding more.

Step 7

Once all the butter has been added, increase the speed to high and beat until the mixture becomes silky and smooth. If the buttercream looks curdled at any point, keep mixing, as it will come together with enough beating.

Step 8

Finally, add the vanilla extract and pinch of salt, mixing until just combined.

Step 9

The mousseline buttercream is ready to use immediately as frosting, or it can be stored. To store, place in an airtight container in the refrigerator for up to 5 days. Bring to room temperature and rewhip before using.
