How to Make Passionfruit Mousse Cake

Prepare the Cake Base
- Preheat the oven to 350°F (175°C).
- Grease and line a springform pan.
- In a bowl, whisk together flour, baking powder, and a pinch of salt.
- In another bowl, beat eggs and sugar until pale and fluffy.
- Add milk, melted butter, and vanilla extract, mixing gently.
- Fold in the dry ingredients.
- Pour batter into the pan and bake for 18-20 minutes or until a toothpick comes out clean.
- Let cool completely.
Make the Passion Fruit Mousse
- Bloom gelatin by sprinkling it over 2 tablespoons of water. Let sit for 5 minutes.
- In a saucepan, combine passion fruit puree, sugar, and lemon juice. Heat gently until sugar dissolves.
- Stir in the bloomed gelatin until fully melted and combined. Let the mixture cool to room temperature.
- In a separate bowl, whip heavy cream to soft peaks.
- Gently fold the cooled passion fruit mixture into the whipped cream until smooth and well combined.
Assemble the Cake
- Place the cooled cake base back into the springform pan.
- Pour the passion fruit mousse over the cake base, smoothing the top.
- Refrigerate for at least 4 hours, preferably overnight, until fully set.
Optional: Add Passionfruit Glaze
- Heat passionfruit juice and sugar gently.
- Stir in the bloomed gelatin until dissolved.
- Let cool slightly, then pour over the set mousse.
- Chill for an additional hour.
Tips for Success
- Use fresh passion fruit puree if available for a more intense flavor.
- Don’t over whip the cream—soft peaks keep the mousse light and airy.
- Bloom gelatin properly to ensure a smooth, stable mousse.
- Chill thoroughly—this helps the mousse set and makes slicing easier.
Serving Suggestions
- Garnish with fresh passion fruit seeds, mint leaves, or edible flowers.
- Pair with a tropical fruit salad on the side.
- Serve chilled for the best texture and flavor.
Passionfruit mousse cake is the perfect blend of tropical flavors and airy texture. Its refreshing tang, creamy mousse, and light cake base make it a standout dessert for both casual get-togethers and elegant celebrations.
