Ingredients
- 170 g unsalted butter, melted (¾ cup / 6oz)
- ¾ cup desiccated coconut (65g / 2.3oz)
- ½ cup caster sugar (superfine sugar) or white granulated sugar (100g / 3 ½oz)
- 195 g plain flour (all purpose flour) (~7oz)
- 1 tin sweetened condensed milk (395g / 14oz)
- ¼ cup fresh lemon juice (60ml)
- ¼ cup strained passionfruit pulp (60ml)
- ½ cup strained passionfruit pulp (125ml)
- 1 ½ teaspoons powdered gelatine
- ¼ cup caster sugar (superfine sugar) or white granulated sugar (50g / 1.8oz)
- ¼ cup cold water (60ml)
- 1 teaspoon passionfruit seeds (optional)
Instructions
- Step 1: Preheat the oven to 180°C (350°F, 160°C fan forced). Line an 8-inch square baking tin with baking paper.
- Step 2: In a large bowl, combine the flour, desiccated coconut, sugar, and melted butter. Mix until well combined, then press the mixture evenly into the base of the prepared pan.
- Step 3: Bake the base for 25 minutes until lightly golden.
- Step 4: For the filling, whisk together the condensed milk, lemon juice, and ¼ cup strained passionfruit pulp. Pour this mixture over the parbaked base.
- Step 5: Bake again for 15 minutes until the filling is firm. Let it cool for about 10 minutes before adding the topping.
- Step 6: For the topping, place the ½ cup strained passionfruit pulp in a small saucepan. Sprinkle the powdered gelatine evenly over the pulp and let it sit for 5 minutes to soften.
- Step 7: Turn the heat to low and stir until the gelatine dissolves completely.
- Step 8: Add the ¼ cup sugar and stir until dissolved. Do not allow the mixture to boil; keep it just hot enough to dissolve the sugar.
- Step 9: Stir in the cold water and add back 1 teaspoon of passionfruit seeds (or to your taste). Mix well, then carefully pour the topping over the slice.
- Step 10: Refrigerate and allow the slice to set for at least 2 hours before cutting and serving.
- Step 11: Enjoy your passionfruit slice and consider leaving a comment or rating to share your experience!
Tips & Variations
- Use fresh passionfruit pulp if possible for the best flavor, or substitute with frozen pulp if fresh is unavailable.
- For extra crunch, sprinkle some toasted coconut flakes on top before the topping sets.
- If you prefer a vegan version, try using agar-agar instead of gelatine and a plant-based condensed milk alternative.
Storage
Store the passionfruit slice in an airtight container in the refrigerator for up to 4 days. To reheat, serve chilled or allow to come to room temperature for 10–15 minutes for a softer texture. This slice is best enjoyed fresh but can be frozen for up to one month; thaw in the refrigerator before serving.

FAQs
Can I use powdered gelatine alternatives?
Yes, agar-agar can be used as a vegetarian substitute, but check the package instructions for quantities and preparation as it sets differently than gelatine.
What can I do if I don’t have passionfruit pulp?
You can substitute with other tropical fruit pulp like mango or guava for a different but delicious flavor, or mix lemon juice with a little passionfruit juice concentrate if fresh pulp is unavailable.

- ½ cup caster sugar (100g / 3 ½oz)
- 195 g plain flour (all purpose flour) (~7oz)

- 1 tin sweetened condensed milk (395g / 14oz)
- ¼ cup fresh lemon juice (60ml)

- 1 ½ teaspoons powdered gelatine
- ¼ cup caster sugar (50g / 1.8oz)
- ¼ cup cold water (60ml)
- 1 teaspoon passionfruit seeds (optional)
Instructions
- Prepare the Shortbread Base: Preheat the oven to 180°C (350°F), or 160°C (320°F) fan forced. Line an 8-inch square baking tin with baking paper to prevent sticking.
- Mix Base Ingredients: In a large bowl, combine the plain flour, desiccated coconut, caster sugar, and melted butter. Stir until the mixture is well combined and has a crumbly texture. Press this mixture evenly into the base of the prepared baking tin to form the shortbread layer.
- Bake the Base: Place the baking tin in the oven and bake for 25 minutes until the base is lightly golden and set.
- Prepare the Filling: In a separate bowl, whisk together the sweetened condensed milk, fresh lemon juice, and ¼ cup of strained passionfruit pulp until smooth and well combined.
- Add Filling to Base: Pour the passionfruit filling evenly over the parbaked shortbread base and return the pan to the oven. Bake for an additional 15 minutes or until the filling is firm to the touch.
- Cool Before Topping: Allow the slice to cool for 10 minutes at room temperature before adding the topping layer.
- Prepare the Topping Gelatine: In a small saucepan, place ½ cup strained passionfruit pulp and sprinkle the powdered gelatine evenly over the surface. Let it sit for 5 minutes to allow the gelatine to soften.
- Dissolve Gelatine: Turn the heat to low and gently stir until the gelatine fully dissolves without bringing the mixture to a boil.
- Add Sugar and Water: Stir in the caster sugar until dissolved, then add the cold water. If desired, stir in 1 teaspoon of passionfruit seeds for texture and flavor. Mix thoroughly.
- Pour Topping Over Slice: Carefully pour the passionfruit gelatine topping over the cooled slice, spreading evenly to cover the surface completely.
- Set the Slice: Refrigerate the slice for at least 2 hours to allow the topping to set firmly before cutting and serving.
- Serve and Enjoy: Once set, cut into squares and serve chilled. Don’t forget to leave a comment and rating if you enjoyed this recipe!
Notes
- Ensure the gelatine does not boil as this can affect its setting properties.
- You can adjust the amount of lemon juice or passionfruit pulp to suit your preferred tartness.
- For a firmer topping, slightly increase the gelatine by ¼ teaspoon if desired.
- This slice is best served chilled and kept refrigerated for up to 3 days.
- If fresh passionfruit is unavailable, frozen pulp or concentrate can be used as a substitute.
