I could not think of a more summery looking cake than my passion fruit coconut mousse cakes which recipe I want to share with you today. 
My little hemisphere cakes look like little bright shining suns to me and I think nothing represents more the summer heat than the sun in a clear blue sky.
Although I like chocolate (mousse) cakes at any time of the year, I tend to eat less of it in the summer time because of the heat; and in general, I prefer "lighter" food when it is boiling hot outside. For a long time, a coconut and passion fruit mousse cake idea was buzzing in my head and two weeks ago, I finally implemented my cake idea in the kitchen. Et voilà, my idea resulted into this delicious light summer mousse cake.
Passion fruit has a very distinctive and strong flavor itself and combing the passion fruit flavor with another flavor can be tricky. Back in January, I shared a passion fruit mousse cake which had a subtle passion fruit flavor conbined with chocolate and I like this cake a lot. But for my passion fruit coconut creation - I think is a very classic combination - I wanted a stronger passion fruit flavor but at the same time not overwhelming, so that the coconut flavor would be present, too. I think I succeded quite well in balancing the passion fruit and the coconut flavor.
The coconut bottom of the cake is on the sweeter side which I like since the sweetness balances out the slightly tart passion fruit mousse. The coconut mousse did not a lot of sugar and such a wonderful coconutty flavor which I really really like and now I want to play more around with different coconut flavors and textures.
If you try this recipe out, let me know how you like the cakes. I am very pleased with this recipe; and if I had a pastry store, I would offer these petit gâteaux every single day.


Passion Fruit Purée

I recommend using a 100 % passion fruit purée for this recipe. In my passion fruit cake recipe, that I shared with you in January, I used a passion fruit juice but I cannot recommend it for this recipe because is does not have enough flavor and you won't be able to get a the yellow mousse color.
Since 100 % passion fruit purée is very strong and tart, I add mango purée to the passion fruit mousse in order to balance out the tartness.
In my experience, it is hard to find passion fruit purée in groccery stores. I always order it here online. I am using a passion fruit purée from the French brand Les vergers Boiron. The purée comes frozen which I think is very convenient because you do not have to use the entire purée at once.

Creamed Coconut 

If you cannot find creamed coconut (made of 100% pure coconut) in your groccery store, you can find it creamed coconut in an Asian groccery store. I use this brand which I get at an Asian store.


You need hemisphere moulds that are 7 cm / 2.75 inches in diameter. I use silicon moulds.
You also need little silicon muffin moulds for the coconut core. The size of the muffin moulds are 7 cm / 2.75 inches in height and 3,5 cm / 1.8 inches in diameter. The muffin moulds will be filled 1/3, so if you have smaller moulds, you can use them instead of my recommended moulds.

Makes hemisphere 8 to 10 cakes ( 7 cm / 2.75 inches in diameter)

Coconut Mousse

  • 55 g / 4 tablespoons coconut milk
  • 10 g / 3/4 tablespoon granulated sugar

  • Remove the pot from the heat and add the coconut cream; stir until the mixture is smooth. Add the gelatin and mix well again until the gelatin is completely melted. Pour the coconut mixture into a small sized bowl and let it cool to room temperature.
  • Whip heavy cream until creamy. 
  • Fold the heavy cream into the coconut mixture. Distribute the coconut mousse into ten small moulds. Do not fill the moulds more than 1/3. See my notes above regarding the size of the moulds.

Passionfruit Glaze

  • 180 g / 3/4 cup passion fruit purée

Add the gelatin and stir until the gelatin is dissolved. Pour the mixture into a flat bowl or plate and let the glaze cool completely and until the glaze thickens up a little bit. 
This is how you make a simple syrup: Place 100 g / 1/2 cup granulated sugar and 100 ml / 1/3 cup and 1 tablespoon water in a pot. Bring the mixture to a boil and let it boil until the granulated sugar is completely dissolved. Let it cool down to room temperature.
Store the simple syrup in the fridge up to two weeks (it in a sealed jar).


  • Shredded coconuts 
  • Slices of fresh coconuts
  • Unmould the passion fruit mousse cakes.
  • Place the frozen cakes on a wire rack and place a deep plate under the wire rack in order to catch the excess glaze and so you can reuse the glaze again.
  • Pour the glaze over the frozen the cakes. Let it set for a minute and if necessary pour the glaze a second time over the mousse cakes. Make sure that the mousse cakes are frozen when pouring the glaze over the cakes. 
  • Sprinkle the lower part of the cakes with shredded coconuts and decorate each top of the cake with a slice of fresh coconut. 
  • Carefully place each cake on a cake board and let it defrost in the fridge. Keep the cakes in the fridge until consumption. The cakes taste the next day just as delicious as on the day of the assembling the cakes.
