What you'll need:

Choc Brownie Base

  • 1 Hill St Cacao Fudge Brownie mix
  • 2 eggs (or flax eggs)
  • 100ml coconut oil
  • 1/4 cup milk of choice

Chocolate Mousse

  • 2 cups raw cashews
  • 1 tsp vanilla essence
  • 1/3 cup maple syrup
  • 1 can (400ml) full fat coconut cream
  • 150g dark chocolate, melted

Chocolate Ganache

    • 2/3 cup coconut cream
    • 150g chocolate of your choice
    • 1/4 cup maple syrup
    • Toasted hazelnuts to decorate


    The night before:

    • Soak cashews in water overnight


    • Bake Hill St Brownie mix according to packet instructions in a lined and round 18cm springform cake tin. Ensure the sides are lined too.

    Chocolate Mousse:

    • While the brownie is baking, rinse and drain the soaked cashews.
    • In a small pot, gently melt chocolate on a low heat until only a few chocolate lumps and take off the heat.
    • Leave for a few minutes and the chocolate should fully melt. •
    • Add into a blender - cashews, vanilla, coconut cream, maple syrup and melted chocolate.
    • Blend into a smooth and creamy mixture.
    • Set aside in the fridge.


    • Gently press the brownie edges out to the edge of the tin (to stop the mousse mixture from running down the sides). Pour the chocolate mousse over the brownie.
    • Set in the freezer for a minimum of 1.5 hours or until firm to touch.
    • Once mousse has set, make the chocolate ganache.
    • Using a double boiler, gently melt the coconut cream, chocolate and maple syrup together. Mix until smooth.
    • Remove cake from the springform tin and carefully peel away the paper lining.
    • Spoon all of the chocolate ganache on top of the cake and use spoon to spread out, try not to over work this as it will set quickly.
    • Top with chopped hazelnuts.
    • Keep in the fridge until ready to serve.
