Instructions
- 1
Preheat oven to 180°C (160°C fan-forced).
- 2
Grease and line a 20 x 30 cm slice tin with baking paper, leaving overhang at sides.
- 3
Whisk plain flour, desiccated coconut, caster sugar, and salt together in a large bowl.
- 4
Pour melted butter into dry ingredients and stir until evenly moistened and crumbly.
- 5
Press mixture firmly and evenly into prepared tin using back of a metal spoon.
- 6
Bake for 15 to 18 minutes until lightly golden around edges.
- 7
Remove tin from oven and cool base completely on a wire rack.
- 8
Sift icing sugar into a clean bowl.
- 9
Add softened butter and fresh passionfruit pulp to icing sugar and beat until smooth.
- 10
Spread passionfruit icing evenly over cooled biscuit base.
- 11
Refrigerate for at least 1 hour until icing sets firm.
- 12
Lift out using baking paper wings and cut into neat squares with a warm, dry knife.
Chef's tips
Ensure the baked base cools completely before adding the icing, or the butter glaze will melt and soak into the crumb. Sifting the icing sugar prevents stubborn lumps. For clean edges, wipe your knife with a warm damp cloth between each slice.
Ingredient substitutions
- fresh passionfruit pulp → canned passionfruit pulp in syrup (reduce icing sugar by 2 tbsp)
- unsalted butter → dairy-free baking margarine
Storage
Store in an airtight container in the refrigerator for up to 5 days, separating layers with baking paper.
Reheating
Not suitable for reheating; serve chilled or slightly brought to room temperature.
Common mistakes to avoid
- •Icing the slice while the biscuit base is still warm, causing the topping to run.
- •Pressing the base too loosely, leading to a crumbly slice that falls apart when cut.
- •Using un-sifted icing sugar which creates grainy bumps in the topping.
