If you’re looking for a dessert that feels luxurious, modern, and bakery-quality, this Passion Fruit White Chocolate Mousse Cake is the kind of showstopper that instantly elevates any table. It combines a buttery biscuit crust, a dense creamy white chocolate mousse filling, and a vibrant passion fruit glaze that delivers the perfect sweet-tart finish.
This is not a fluffy whipped mousse cake. The texture is intentionally smooth, sliceable, and elegant — similar to a high-end pâtisserie cheesecake. Each layer is balanced: the crust adds structure, the mousse provides richness, and the passion fruit topping cuts through the sweetness with bright tropical acidity.
The result is a dessert that looks refined, tastes fresh, and feels indulgent without being heavy.
Why This Passion Fruit White Chocolate Mousse Cake Is Special
This cake succeeds because of contrast and balance:
- Rich white chocolate meets sharp tropical fruit
- Creamy mousse meets firm biscuit crust
- Smooth filling meets glossy gel topping
- Sweetness balanced by acidity
Many mousse cheesecakes lean too sweet. The passion fruit prevents that. Its natural tartness keeps every bite refreshing and prevents palate fatigue.
It’s the kind of dessert that impresses guests but doesn’t overwhelm them.
Ingredients
Crust
- 200 g graham crackers or digestive biscuits
- 100 g melted butter
- 2 tbsp sugar
White Chocolate Mousse Filling
- 250 g white chocolate
- 300 g cream cheese (room temperature)
- 200 ml heavy cream (cold)
- 100 ml passion fruit pulp (strained or blended)
- ½ cup powdered sugar
- 1 tsp vanilla
- 2 tsp gelatin + 4 tbsp cold water
Passion Fruit Topping
- 150 ml passion fruit pulp (with seeds)
- 3 tbsp sugar
- 1 tsp gelatin + 2 tbsp water
Step-by-Step Method
Prepare the Crust
Crush the biscuits into fine crumbs. You want a sandy texture with no large chunks, so the base holds cleanly when sliced.
Mix the crumbs with melted butter and sugar until evenly coated. Press firmly into the bottom of an 8-inch springform pan. Use the bottom of a glass to compact it tightly — a firm crust prevents crumbling later.
Chill for 20 minutes to set.
Make the White Chocolate Mousse Filling
Bloom the gelatin in cold water and let it sit for 5 minutes.
Melt the white chocolate gently using a double boiler or short microwave bursts. Stir until smooth and let it cool slightly — it should be fluid but not hot.
Beat the cream cheese and powdered sugar until perfectly smooth. No lumps should remain. Add passion fruit pulp and vanilla and mix again.
Melt the bloomed gelatin until liquid and immediately mix it into the cream cheese mixture.
Fold in the melted white chocolate until fully incorporated.
In a separate bowl, whip the cold heavy cream to soft peaks. Gently fold it into the mousse mixture in batches. This step adds lightness while keeping the mousse dense and creamy.
Pour the filling over the chilled crust and smooth the top.
Refrigerate for 4–6 hours, preferably overnight, until fully set.
Prepare the Passion Fruit Glaze
Bloom gelatin in water.
Heat the passion fruit pulp with sugar just until warm — do not boil. Stir in the melted gelatin and mix until smooth.
Let the mixture cool until slightly thick but still pourable. Pour it gently over the chilled mousse layer.
Return to the refrigerator for about 1 hour to set the glaze.

FAQs
Can I make this cake without gelatin?
Yes. You can replace gelatin with agar-agar, but texture will be firmer and less creamy.
Can I use canned passion fruit pulp?
Absolutely. Frozen or canned pulp works well — just strain if needed.
Can I substitute mascarpone for cream cheese?
Yes. Mascarpone makes a richer, silkier filling.
Why is my mousse not setting?
Most likely insufficient chilling time or gelatin not fully dissolved.
Can I make this ahead of time?
Yes — this cake is ideal for preparing 1 day in advance.
Can I make it sweeter?
You can add more powdered sugar, but balance is key. Passion fruit should remain tart.
