Ingredients

Scale

Base Ingredients:

  • 1 cup self-raising flour
  • ¾ cup desiccated coconut
  • ½ cup brown sugar
  • 2 teaspoons ground cinnamon
  • 150 grams (5.3 ounces) melted butter
  • 80 grams (2.8 ounces) butter
  • ¼ cup cocoa powder

Chocolate Ingredients:

  • 300 grams (10.6 ounces) dark chocolate, broken into small pieces
  • 3 eggs, separated
  • ¼ cup caster sugar

Topping/Filling Ingredients:

  • 1 ½ cups cream
  • 1 cup caster sugar
  • 1 cup water
  • 1 tablespoon gelatine powder
  • 2 teaspoons vanilla extract

Instructions

  1. Prepare the oven environment by heating to 180°C (350°F) with rack positioned in the middle.
  2. Prepare a rectangular baking vessel by lightly coating with cooking spray and lining the base with parchment paper, ensuring complete coverage.
  3. Combine dry foundation ingredients including flour, coconut, brown sugar, and ground cinnamon in a mixing bowl, creating a uniform mixture.
  4. Introduce melted butter to the dry ingredients, stirring until a cohesive crumbly texture develops.
  5. Transfer the prepared mixture into the lined pan, using fingertips or a flat utensil to create an even, compact base layer.
  6. Place pan in preheated oven and bake for approximately 12 minutes until the surface achieves a golden-brown appearance. Remove and allow to cool completely.
  7. Create chocolate mousse by gently melting butter, cocoa, and chocolate in a saucepan over low temperature, stirring consistently until achieving a smooth consistency.
  8. Remove chocolate mixture from heat and rapidly incorporate egg yolks, understanding the mixture might temporarily appear lumpy.
  9. Separately, whip egg whites, progressively adding sugar until stiff, glossy peaks form.
  10. Carefully fold a small portion of chocolate mixture into egg white preparation, then gradually integrate remaining chocolate.
  11. Gently fold whipped cream into mousse until thoroughly incorporated.
  12. Pour mousse evenly over cooled base, using a spatula to create a smooth surface.
  13. Refrigerate for 4 hours to allow complete setting.
  14. Prepare marshmallow topping by combining sugar, water, and gelatine in a saucepan, heating gently while stirring until complete dissolution.
  15. Increase heat to medium, simmering for 6 minutes and stirring periodically. Allow mixture to cool for 5-10 minutes.
  16. Transfer liquid to stand mixer and beat at high speed for 9 minutes until transformation occurs, creating a thick, white, billowy texture.
  17. Incorporate vanilla extract into marshmallow mixture.
  18. Spread marshmallow layer uniformly over set mousse, ensuring smooth, even coverage.
  19. Return to refrigerator and chill for an additional 4 hours until completely firm.

Notes

  • Customize the base by swapping coconut with crushed graham crackers or gluten-free cookies for different texture and dietary needs.
  • Ensure egg yolks are at room temperature to prevent lumpy chocolate mixture and create smoother consistency.
  • Use high-quality dark chocolate with at least 70% cocoa for richer, more intense flavor profile.
  • Handle egg whites carefully during folding to maintain maximum volume and create lighter, airier mousse texture
