🛒 Ingredients

8 servings

8
  • 1 can (14 oz / 397 g) sweetened condensed milk
  • ¾ cup (200 g) heavy whipping cream
  • 1 tablespoon cornstarch
  • 2 cups (200 g) shredded coconut
  • ½ cup (120 ml) coconut milk
  • 2 dark chocolate and coconut truffles, for garnish

Directions

  1. 1

    Whisk together the sweetened condensed milk, heavy cream, coconut milk, and cornstarch in a medium saucepan until the cornstarch is fully dissolved.

  2. 2

    Cook over low heat, stirring continuously with a wooden spoon, until the mixture thickens to a spreadable consistency, about 8–10 minutes.

  3. 3

    Stir in the shredded coconut, then remove from heat and let cool slightly before assembling the cake.

  4. 4

    Slice your cake horizontally into two even layers. Spread half of the coconut filling generously over the bottom layer, reaching all the way to the edges.

  5. 5

    Place the top layer back on and cover the entire surface and sides of the cake with the remaining filling.

  6. 6

    Garnish with chocolate truffles and refrigerate for at least 30 minutes before slicing to allow the filling to set.

💡 Chef's Tip

Toast the shredded coconut in a dry skillet beforehand for a deeper, nuttier flavor. For a firmer filling, increase the cornstarch to 1½ tablespoons.
