Detailed Recipe Steps

Now that we have everything prepared, let’s get started on crafting this delicious Lemon Mousse Cake.

Prepare the Cake:

Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan to prevent sticking.
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 3-5 minutes, and it’s essential for achieving a good texture.
Next, add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and lemon zest to infuse the batter with flavor.
In a separate bowl, whisk together the flour, baking powder, and salt. This will ensure that the leavening agent is evenly distributed throughout the cake.
Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined, being careful not to overmix as this can lead to a dense cake.
Pour the batter into the prepared cake pan and smooth the top with a spatula.
Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Prepare the Lemon Mousse:

In a medium bowl, beat the heavy cream, powdered sugar, and vanilla extract until soft peaks form. This step is crucial for achieving that airy mousse texture.
In another bowl, beat the egg whites with a pinch of salt until stiff peaks form. This will help incorporate air and lightness into the mousse.
Gently fold the lemon curd into the whipped cream until combined, being careful to maintain the volume of the whipped cream.
Finally, carefully fold in the beaten egg whites until no white streaks remain. This will ensure that your mousse is light and fluffy.

Assemble the Cake:

Once the cake has cooled completely, slice it in half horizontally to create two layers.
Place one layer of the cake on a serving plate and spread half of the lemon mousse over the first layer.
Top with the second layer of cake and spread the remaining mousse on top.
Chill the cake in the refrigerator for at least 2 hours to allow the mousse to set. This step is important for achieving the right consistency.

Serve:

Before serving, garnish with lemon slices and fresh mint leaves to add a pop of color and freshness.
Slice and enjoy your refreshing lemon mousse cake!
