✨ Introduction:

Light, fluffy, and bursting with citrus flavor, Lemon Mousse Cake is the perfect blend of elegance and indulgence.

Originating as a fusion between classic French mousse and the airy sponge cake found in European patisseries, this dessert showcases how versatile lemons can be—tart, sweet, refreshing, and luxurious all at once.

📜 A Brief History:

The use of lemons in desserts dates back centuries. The French popularized lemon curd and mousse in the 18th century, while Italian liqueurs like Limoncello added a boozy citrus zing to cakes and pastries.

It’s been beloved by home bakers and professional pastry chefs alike.

  • Zest of 2 lemons 🍋
  • 1/2 cup fresh lemon juice 🍋
  • 4 tbsp unsalted butter, cut into cubes 🧈

For the Lemon Mousse:

  • 1 cup heavy whipping cream 🥛

  • 1 tsp vanilla extract 🍦
  • 1/2 cup prepared lemon curd (from above) 🍋

🧁 Formation (Assembly) Steps:

Step 1: Make the Sponge Cake

  1. Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans.
  2. In a large bowl, beat the eggs and sugar using an electric mixer on high speed for about 8–10 minutes, until thick, pale, and tripled in volume.
  3. Gently fold in the sifted flour in batches to avoid deflating the batter.
  4. Add melted butter and vanilla extract, fold carefully.
  5. Divide batter evenly between pans. Bake for 20–25 minutes or until golden and a toothpick inserted comes out clean.
  6. Cool in pans for 10 minutes, then remove and cool completely on wire racks.
  7. (Optional) Brush each sponge with Limoncello for added flavor.

Step 2: Prepare the Lemon Curd

  1. In a heatproof bowl, whisk together yolks, sugar, lemon zest, and juice.
  2. Place the bowl over a saucepan of simmering water (double boiler method). Cook while stirring constantly for 7–10 minutes until thickened.
  3. Remove from heat and stir in butter until smooth.
  4. Let cool, then refrigerate until ready to use.

Step 3: Whip the Lemon Mousse

  1. In a chilled mixing bowl, beat the heavy cream, powdered sugar, and vanilla until soft peaks form.
  2. Gently fold in the lemon curd to create a light, creamy mousse. Refrigerate for at least 30 minutes before using.

Step 4: Assemble the Cake

  1. Place one sponge layer on a cake stand. Spread a layer of lemon mousse evenly.
  2. Add the second sponge on top. Cover the top and sides with remaining mousse.
  3. Chill the entire cake for at least 4 hours or overnight for best results.

Step 5: Decorate

  • Pipe whipped cream around the edges.
  • Garnish with lemon zest, curls of white chocolate, and fresh mint.
  • Serve chilled for a refreshing bite!
