Lemon Blueberry Mousse Cake Ingredients
• A delightful combination of flavors awaits!
For the Crust
- Cooking Spray – Greasing the pan is essential, and you can use non-stick spray instead of butter for convenience.
- Nilla Wafers (30, crushed) – This cookie forms the base crust; feel free to swap for graham crackers or any similar cookie.
- Butter (5 Tbsp, melted) – Binds the crust together; coconut oil works as a great dairy-free alternative.
For the Mousse
- Blueberries (1 1/2 cups, plus garnish) – The star of the dessert; frozen blueberries can be used if fresh aren’t available.
- Lemon Juice (2 Tbsp + 1 Tbsp) – Adds brightness and acidity; lime juice can serve as an interesting substitute.
- Lemon Zest (2 tsp) – Enhances that vibrant lemon flavor; fresh zest is best, but it can be omitted in a pinch.
- Unflavored Gelatin (2 tsp) – Provides the mousse’s structure; agar-agar is a fantastic vegetarian alternative.
- White Chocolate Chips (2 1/2 cups) – Adds a rich sweetness to the mousse, but you could try dark chocolate for a deeper taste.
- Heavy Cream (3 cups, divided) – Creates that lush, airy texture; opt for coconut cream if you’re going dairy-free.
- Powdered Sugar (1/2 cup) – Sweetens the mousse; consider reducing the amount or substituting with a sugar alternative.
- Granulated Sugar (1/4 cup) – Sweetens the blueberry sauce; maple syrup can be a delicious alternative here.

How to Make Lemon Blueberry Mousse Cake
Grease the pan: Start by lightly coating a springform pan with cooking spray to ensure your mousse cake releases easily later.
Prepare the crust: In a mixing bowl, combine the crushed Nilla wafers and melted butter. Press this mixture firmly into the bottom of the prepared pan to form an even crust, then chill it in the refrigerator for 15 minutes.
Make blueberry sauce: In a saucepan, simmer 1 1/2 cups of blueberries with 2 tablespoons of lemon juice and 1/4 cup of granulated sugar over medium heat. Cook until the blueberries break down and the mixture reduces, about 5-7 minutes. Strain to remove solids and cool the sauce to room temperature.
Bloom the gelatin: Sprinkle 2 teaspoons of unflavored gelatin over your cooled blueberry sauce and let it sit for 5 minutes. Then, gently heat until dissolved, mixing in the melted 2 1/2 cups of white chocolate until smooth and combined.
Whip the cream: In a large bowl, use an electric mixer to whip 3 cups of heavy cream with 1/2 cup of powdered sugar until soft peaks form. Be careful not to over-whip!
Combine the mixtures: Gently fold the whipped cream into the cooled blueberry mixture until fully combined, creating a fluffy mousse.
Assemble the cake: Spoon the luscious mousse over the chilled crust, spreading it evenly. Refrigerate for at least 4 hours or until fully set.
Garnish and serve: Before serving, top the cake with additional blueberries for a touch of elegance. Enjoy this delightful treat!
Optional: Add a sprig of fresh mint for a lovely garnish.

Lemon Blueberry Mousse Cake Recipe FAQs
What is the best way to select ripe blueberries?
Absolutely! When choosing blueberries, look for ones that are plump, firm, and covered in a powdery bloom. Avoid any with dark spots or wrinkles, as these are signs they’re past their prime. If you’re buying frozen blueberries, opt for those that are not clumped together, which indicates they’ve been properly frozen.
How do I store leftovers of Lemon Blueberry Mousse Cake?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. This ensures the mousse maintains its creamy texture and flavors. If you prefer to make it ahead of time, consider preparing it a day in advance. Just be sure to garnish before serving for the best presentation!
Can I freeze Lemon Blueberry Mousse Cake?
Certainly! If you want to freeze leftovers, wrap the mousse cake tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can last in the freezer for up to 1 month. When you’re ready to enjoy it again, let it thaw in the refrigerator overnight before serving. This method preserves the delightful flavor and texture!
What should I do if the mousse doesn’t set properly?
If your mousse doesn’t set as expected, the most common issue could be with the gelatin. Make sure it dissolves fully in warm liquid; if it hasn’t, it won’t provide the necessary structure. If you encounter this, you can reheat the mousse gently, dissolve more gelatin in a small amount of water, and mix it in. Chill it again until set.
Are there any dietary considerations for this recipe?
Very! If you’re serving this mousse cake to guests with allergies or dietary restrictions, substitutes are easily available. You can use coconut cream instead of heavy cream for a dairy-free option, and swap white chocolate for dark chocolate if someone has a sensitivity to dairy. Always check ingredient labels to ensure they meet specific dietary requirements.
