How to Make Lemon Mousse Cake
Creating a stunning Lemon Mousse Cake involves meticulous steps that ensure a flavorful outcome. Let’s break down the process step-by-step.
Step 1: Prepare the Sponge Cake
Preheat your oven to 325 degrees F (163 degrees C). Line the bottom of a 10-inch springform pan with parchment paper but do NOT grease the sides. This is crucial because greasing will interfere with the cake’s rise.
In a bowl of an electric mixer fitted with a whisk attachment, combine the sugar, eggs, and vanilla extract. Beat on medium-high speed for about 10 minutes until the mixture is foamy and pale. This aerating process is essential for a light sponge.
Reduce the mixer speed to medium-low. With the mixer running, gradually sprinkle in rounded tablespoons of the sifted flour. Once the flour is fully incorporated, stop the mixer to prevent overmixing, which can deflate the batter.
Remove 1 to 2 cups of the sponge cake batter and mix it with the melted butter. Carefully add this mixture back into the main batter, gently folding it in with a rubber spatula to maintain the airiness.
Pour the final batter into the prepared springform pan and bake for approximately 45 minutes. Start checking for doneness at the 40-minute mark; the cake is ready when it springs back when lightly pressed. Allow it to cool completely in the pan for at least a couple of hours before gently loosening it from the sides with a sharp knife.
Step 2: Make the Lemon Curd
While the cake cools, it’s time to prepare the lemon curd. In a small saucepan, combine the egg yolks, sugar, lemon juice, and zest. Cook this mixture over medium-low heat for about 10 minutes, stirring constantly until it thickens enough to coat the back of a wooden spoon.
Remove the saucepan from heat and stir in the butter, a few pieces at a time, until completely smooth. It is essential to allow the curd to cool in the fridge once prepared, as it will develop deeper flavors as it chills.
Step 3: Prepare the Lemon Mousse
Once the lemon curd has chilled, it’s time to whip the cream for the mousse. In a separate bowl, whip 2 cups of whipping cream, icing sugar, and vanilla extract until firm peaks form. This whipped cream will be folded into the lemon curd to create a light and fluffy mousse.
Using a rubber spatula, gently fold half of the chilled lemon curd into the whipped cream until thoroughly combined. Reserve the other half of the lemon curd for topping the cake later.
Step 4: Assemble the Cake
With the sponge cake cooled and the mousse ready, it’s time to assemble. If desired, sprinkle the cooled sponge cake with Limoncello liqueur for added flavor. Pour the prepared lemon mousse over the sponge cake in the springform pan. Cover with plastic wrap and refrigerate for several hours or overnight to allow the mousse to set properly.
When the mousse has set, carefully run a small sharp knife around the edge of the mousse to loosen it from the pan. Slide the cake from the bottom of the pan onto a serving plate, and spread the reserved lemon curd evenly over the top.
To finish, pipe vanilla whipped cream around the edge or dollop it using rounded spoonfuls. For a touch of elegance, you can garnish the cake with candied lemon peel.

How to Store Lemon Mousse Cake
Storing your Lemon Mousse Cake properly will ensure that it stays fresh and flavorful for as long as possible.
Proper Storage Methods
To store the Lemon Mousse Cake, cover it with plastic wrap or place it in an airtight container. It can be kept in the refrigerator for up to 3 days. If you’ve made the cake ahead of time, it’s best stored unassembled; keep the sponge, mousse, and curd separate until you are ready to serve.
Tips for Reheating or Freezing
This dessert is best served chilled and does not require reheating. If you have leftover cake that you want to freeze, slice it into individual pieces wrapped tightly in plastic wrap followed by aluminum foil. They can be stored in the freezer for up to a month. Thaw in the refrigerator overnight before serving.
Tips to Make Lemon Mousse Cake
To ensure your Lemon Mousse Cake turns out perfectly, consider these helpful tips and avoid common pitfalls.
Common Mistakes to Avoid
- Overmixing the cake batter can lead to a dense sponge; always mix gently after adding the flour.
- Be cautious not to bake the sponge cake too long, as a dry cake will affect the overall texture of the dessert.
- Ensure the lemon curd cools thoroughly; if it’s too warm when you fold it into the whipped cream, it could cause the cream to deflate.
Helpful Tips for Better Results
- Use fresh lemons for the best flavor – bottled lemon juice can lack the vibrant taste of fresh juice.
- Allow the cake to cool completely before assembling the mousse to prevent melting.
- If you want a smoother texture in your lemon curd, strain the mixture before chilling.
Variation of Lemon Mousse Cake
There are several ways to adapt this delightful dessert to cater to various tastes and dietary preferences.
Suggested Variations or Twists on the Recipe
- Berry-Lemon Mousse Cake: Add a layer of fresh berries or berry puree between the mousse and sponge layers for a burst of flavor.

Adjustments for Dietary Preferences
To make this cake gluten-free, you can substitute traditional flour for almond meal or a gluten-free flour blend. For vegan options, use flax eggs for the cake and coconut cream for the mousse, ensuring all other ingredients are plant-based.
FAQs
