Keyword: Dessert, no bake, Thermomix
Servings: 24 pieces


  • 170 grams sweetened condensed milk
  • 125 grams butter
  • 250 grams Marie Biscuits or similar plain biscuits
  • 1 tbsp lemon zest
  • 85 grams desiccated coconut

Passionfruit Icing

  • 300 grams 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.
  • Add the biscuits to your Thermomix bowl and mix for 10 seconds, speed 8 to crush. Transfer to a separate bowl until needed.
  • Without washing the bowl, add the condensed milk and butter to your Thermomix bowl and cook for 3 minutes, 60 degrees, speed 2 or until melted and combined.
  • Add the crushed biscuits, lemon zest and coconut to your Thermomix bowl and mix for 10 seconds, speed 4 to combine.  Scrape down the sides of your bowl and mix for a further 5 seconds, speed 4 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, passionfruit pulp and butter into a clean Thermomix bowl and mix for 10 seconds on speed 3 to combine. If your icing is a little thick, add a teaspoon of water.
  • 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.
