Servings: 24 pieces


  • 1/2 cup sweetened condensed milk
  • 125 grams butter melted
  • 250 grams Marie Biscuits or similar plain biscuits
  • 1 tbsp lemon zest
  • 1 cup desiccated coconut

Passionfruit Icing

  • 2 cups icing sugar
  • 3 passionfruit pulp only
  • 20 grams butter softened


  • Line a 28 x 18cm slice tin with baking paper, making sure you leave paper hanging over the sides.
  • Place the biscuits into a food processor and blitz until they are finely crushed.  
  • In a small bowl, add the condensed milk and melted butter and stir to combine. 
  • Place the crushed biscuits, lemon zest and coconut to the melted butter mixture into a large bowl and mix to combine.
  • Pour the condensed milk and butter mixture into the bowl with the crushed biscuits and mix well to combine.
  • Pour the mixture into your prepared slice tin and use the back of a spoon to press the mixture into the tin before placing it into the fridge for 30 minutes to chill.
  • To make the passionfruit icing, place the icing sugar mixture, passionfruit pulp and butter into a small bowl and mix until it’s smooth.
  • Pour the icing over the chilled slice base and use a butter knife to help spread it across the slice.
  • Place the slice back into the fridge for three hours (or until the icing has set) before cutting into squares to enjoy.


  • Depending on the size of your passionfruit, you may need to add a teaspoon of water to your icing mixture to help it get to the right consistency.  
  • I used Marie Biscuits for this recipe, however you can also use any other plain biscuit.
