“A good génoise mousseline is all about balance,” explains renowned pastry chef, Jean Dubois. “The delicate crumb of the génoise paired with the richness of the buttercream creates a harmony of flavors and textures that is simply divine.”

Ingredients for a Heavenly Génoise Mousseline

For the Génoise Cake:

• 6 large eggs, at room temperature
• 1 cup (120g) granulated sugar
• 1 teaspoon pure vanilla extract
• 1 cup (125g) cake flour, sifted
• 1/4 cup (30g) unsalted butter, melted and cooled

For the Buttercream Filling:

• 1 cup (2 sticks) unsalted butter, softened
• 3 cups (360g) powdered sugar, sifted
• 1/4 cup (60ml) heavy cream
• 1 teaspoon pure vanilla extract

Baking the Perfect Génoise Mousseline: A Step-by-Step Guide

Making the Génoise Cake:

1. Prepare the Pans: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line the bottoms with parchment paper for easy removal later.
2. Whip the Eggs: In the bowl of a stand mixer fitted with the whisk attachment, beat the eggs and sugar on high speed until the mixture is pale yellow and has tripled in volume. This should take about 5-7 minutes. You’ll know it’s ready when the batter falls from the whisk in thick ribbons.
3. Add Vanilla and Dry Ingredients: Gently fold in the vanilla extract. Gradually add the sifted cake flour in two batches, gently folding it into the egg mixture with a rubber spatula. Be careful not to overmix, as this can deflate the batter.
4. Incorporate the Butter: Drizzle the melted and cooled butter down the side of the bowl. Gently fold the butter into the batter until just combined.
5. Bake: Divide the batter evenly between the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
6. Cool Completely: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

Preparing the Buttercream Filling:

1. Beat the Butter: In a large bowl, beat the softened butter with an electric mixer until light and fluffy.
2. Add Sugar Gradually: Gradually add the powdered sugar, one cup at a time, beating well after each addition.
3. Incorporate Cream and Vanilla: Pour in the heavy cream and vanilla extract. Beat on high speed until the buttercream is smooth and creamy.

Assembling the Génoise Mousseline:

1. Level the Cakes: If necessary, use a serrated knife to carefully level the tops of the cooled cakes so they are even.
2. Fill and Frost: Place one cake layer on a serving plate. Spread half of the buttercream evenly over the cake. Top with the second cake layer. Frost the entire cake with the remaining buttercream.
3. Decorate: You can leave the cake as is or get creative with decorations. Use a piping bag to create elegant swirls, or decorate with fresh fruit, chocolate shavings, or chopped nuts.

Tips for Génoise Mousseline Success:

• Room Temperature Ingredients: Using room-temperature eggs is crucial for achieving maximum volume when whipping.
• Don’t Overmix: Overmixing the batter can result in a dense, chewy cake. Fold the ingredients gently until just combined.
• Cooling is Key: Allow the cakes to cool completely before frosting to prevent the buttercream from melting.

FAQs about Génoise Mousseline:

Q: Can I make génoise mousseline ahead of time?

A: Absolutely! You can bake the cake layers up to two days in advance. Wrap them tightly in plastic wrap and store them at room temperature. The buttercream can also be made ahead of time and stored in the refrigerator for up to three days.

Q: My génoise cake sank in the middle. What went wrong?

A: This is usually a sign that the cake was underbaked. Make sure to insert a toothpick into the center of the cake – it should come out clean when the cake is done. You can also try increasing the oven temperature slightly.

Q: Can I use a different type of frosting for génoise mousseline?

A: While traditional génoise mousseline calls for buttercream, you can get creative with your fillings. Whipped cream, fruit preserves, or even a chocolate ganache would all pair well with the delicate flavor of the cake.
