Instructions

Making the Cake:

1. Preheat your oven to 350˚F (175˚C). Butter a cake pan or springform pan, and line the bottom with parchment paper.
2. Beat 3 large eggs with 1/2 cup sugar using a whisk attachment at high speed for about 6 minutes (7 minutes for cold eggs).
3. Sprinkle 1/2 cup flour on top of the egg mixture and gently fold it in with a spatula until incorporated. Avoid overmixing, as this can affect the rise.
4. Pour the batter into the prepared pan and bake for 23 minutes. Once done, allow the cake to cool to room temperature (you can speed this up by placing it in the freezer for 10 minutes).

Making the Raspberry Mousse:

1. In a small saucepan, combine 1 1/4 cups raspberries and 1/4 cup sugar. Cook over medium heat until it thickens to a raspberry sauce. Strain the mixture through a fine mesh sieve to remove the seeds, pressing with a spoon to extract as much juice as possible.
2. Return the juice to the saucepan and stir in 1 tablespoon lemon juice and 1/2 tablespoon unflavored gelatin. Heat just enough to dissolve the gelatin, then remove from heat and let cool to room temperature. Be sure it doesn’t cool too long, as the gelatin will start to set.
3. Whip 1 cup heavy whipping cream to soft peaks, then add 1 1/2 tablespoons powdered sugar and continue to beat until stiff peaks form. Refrigerate the whipped cream until needed.
4. Once the raspberry sauce has cooled to room temperature, gently fold it into the whipped cream in small portions (about 1/4 of the sauce at a time). Spread the mousse over the cooled cake and refrigerate for 2-3 hours, or overnight to set.

Decorating the Cake:

1. When the mousse is firm enough to decorate, whip 1 cup heavy cream with 1 1/2 tablespoons powdered sugar until stiff peaks form.
2. Pipe the whipped cream around the perimeter of the cake, then decorate with fresh raspberries and tiny basil leaves for a touch of elegance.

Why You’ll Love This Recipe

• Fresh and Light: The raspberry mousse adds a refreshing and fruity touch to the light sponge cake.
• Elegant Presentation: This cake is as visually stunning as it is delicious, perfect for special occasions.
• Easy to Make Ahead: You can prepare the mousse cake in advance, making it a great option for stress-free entertaining.

Tips

• Room Temperature Ingredients: Ensure your eggs and cream are at room temperature for the best results in texture and whipping.
• Don’t Rush the Cooling Process: Let the cake cool completely before adding the mousse, and make sure the raspberry sauce is room temperature before mixing it with the whipped cream to prevent it from setting prematurely.
• Gelatin Care: Be cautious with the gelatin, as it begins to set quickly once cooled. If it sets too much, it may not mix smoothly with the whipped cream.

Variations and Substitutions

• Other Fruits: Try using strawberries, blueberries, or mixed berries for a different flavor profile.
• Gluten-Free: Use a gluten-free flour blend to make the cake gluten-free.
• Non-Dairy Options: Swap the heavy cream for coconut cream or a non-dairy alternative to make it dairy-free.

FAQs

Can I use frozen raspberries instead of fresh?
Yes, frozen raspberries work well in this recipe. Just make sure to thaw and drain them before using.

Can I make this cake a day in advance?
Yes, this cake actually tastes better when prepared the day before, as the mousse has time to set and the flavors meld together.

What if my mousse doesn’t firm up?
Ensure that the raspberry sauce has cooled to room temperature before mixing it with the whipped cream. If the gelatin hasn’t dissolved fully, it may cause the mousse to stay too soft.

• Pair with Tea or Coffee: This raspberry mousse cake is an excellent treat for afternoon tea or after dinner.
• Add a Dusting of Powdered Sugar: For a simple yet elegant finish, lightly dust the top with powdered sugar before serving.
