Bottom
- Preheat the oven to 200C/400F. Prepare a cake pan by greasing it and lining it with parchment paper. My pan had a 18cm diameter.
- In a bowl, using your hands crumble together the ingredients for the bottom till it becomes a somewhat “shapeable” crumble.
- Transfer the mixture to the pan. Press out evenly and prick with a fork. Bake for 18-20 minutes or until firm and golden. Let cool while making the mousse.
Mousse
- Using a food processor or stick blender, mix the tofu completely smooth. While the food processor or stick blender is still running, pour in the melted chocolate and mix until combined. Transfer to a bowl.
- In a separate bowl, whip the aquafaba as hard and fluffy as possible. It may take a couple of minutes. Then transfer around half the whipped aquafaba to the chocolate mixture and carefully fold it together. Add the rest of the aquafaba and repeat the process.
- Transfer the mousse to the cooled crumble bottom and spread evenly. Let cool in the fridge for an hour. If you’re just using fresh passion fruit, simply top the cake with it and serve, and skip the next steps.
Passion fruit topping (can be skipped if just using fresh passion fruit)
- Put all the ingredients in a sauce and bring to a simmer on medium high heat. Let cook for 2 minutes until starts to thicken. If you’re not sure if the mixture will set, spread a little on a plate and put in the freezer for a minute or two till cooled and check the texture.
- Transfer the mixture and pour over the mousse cake. Let set in the fridge for an hour before serving. Serve and enjoy!
