2. Ingredients for the Delicious Lemon Blueberry Mousse Cake
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup freshly squeezed lemon juice
- Zest of 1 lemon
- 1 cup fresh blueberries
- 2 cups heavy cream
- 1/2 cup powdered sugar
- 1 tablespoon unflavored gelatin
- 3 tablespoons water
- Additional blueberries and lemon zest for garnish
3. How to Make the Ultimate Lemon Blueberry Mousse Cake
Step 1: Prepare the Cake Layer
Preheat your oven to 350°F (175°C). In a bowl, whisk together the all-purpose flour, baking powder, and salt. In a separate large bowl, cream the softened butter and granulated sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract, lemon zest, and lemon juice. Gradually add the dry ingredients to the wet mixture until just combined. Fold in half of the fresh blueberries gently. Pour the batter into a greased 9-inch cake pan and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely before assembly.
Step 2: Make the Blueberry Lemon Mousse
In a small bowl, sprinkle the unflavored gelatin over 3 tablespoons of water and let it bloom for 5 minutes. Heat the gelatin gently until fully dissolved. In a blender, purée the remaining blueberries until smooth. In a mixing bowl, whip the heavy cream and powdered sugar until soft peaks form. Gently fold in the blueberry purée and dissolved gelatin until well incorporated. Chill the mousse mixture for about 30 minutes to thicken slightly.
Step 3: Assemble the Lemon Blueberry Mousse Cake
Once the cake layer is cooled, spread an even layer of the blueberry lemon mousse over it. Refrigerate the cake for at least 2 hours to allow the mousse to set. Before serving, decorate the top with fresh blueberries and a sprinkle of lemon zest for an extra burst of flavor and visual appeal.
4. Tips for Perfect Lemon Blueberry Mousse Cake
- Use fresh blueberries for vibrant color and better flavor.
- Chill the mousse until it is just thick enough to spread smoothly.
- Ensure the cake is completely cooled before assembling to prevent melting of the mousse.
- Garnish with additional lemon zest and blueberries for presentation.
