Step 2: Prepare the Butter

Begin by creaming the softened butter in a mixing bowl. Use a stand mixer or a hand mixer on medium speed until the butter is light and fluffy, which usually takes about 3 to 5 minutes. This step is crucial as it incorporates air into the butter, contributing to the final texture of the frosting.

Step 3: Make the Sugar Syrup

In a small saucepan, combine the granulated sugar and 1/4 cup of water over medium heat. Stir until the sugar dissolves and the mixture comes to a simmer. Allow it to boil without stirring until the syrup reaches 240°F (soft ball stage) on a candy thermometer. Once it reaches this temperature, remove it from the heat.

Step 4: Incorporate the Egg Yolks

While the sugar syrup cooks, beat the egg yolks in a clean bowl until they become pale and thick, about 2 to 3 minutes. With the mixer running on medium, slowly pour the hot sugar syrup into the egg yolks in a thin stream. Be careful to avoid pouring it directly onto the beaters to prevent splatter. Continue to mix until the mixture cools to room temperature and forms a thick, glossy meringue.

Step 5: Combine Everything Together

Once the meringue has cooled, gradually add the creamy butter to the meringue. Mix on low speed until well combined, then add the vanilla extract and a pinch of salt. Beat on medium speed until the frosting is smooth and fluffy, which should take about 2 to 5 minutes. If it seems too stiff, you can add a teaspoon of milk to reach your desired consistency.

Step 6: Frost Your Treats

Now that your French buttercream frosting is ready, you can use it to frost cakes, cupcakes, or any other desserts you desire. Enjoy the rich flavor and smooth texture that this homemade frosting provides!
