WHY MAKE IT
A little comfort, a lot of flavor.
Passion Fruit Coconut Slice delivers an invigorating balance of sharp tropical acidity and mellow, buttery pastry. Popular throughout Australian and New Zealand home bakeries, this layered slice pairs a dense, crumbly shortbread base with a smooth, stovetop-cooked passion fruit curd. The natural tartness of passion fruit balances the rich dairy notes of butter and the nutty sweetness of dried coconut. By incorporating desiccated coconut directly into the biscuit dough, the base gains extra texture and aromatic richness that anchors the bright citrusy curd. Finished with crisp toasted coconut flakes, this chilled dessert offers multi-layered contrast in every bite, making it an elegant centerpiece for afternoon tea, family gatherings, or casual warm-weather refreshments.
Mastering the Stovetop Passion Fruit Curd
Achieving a thick, velvety fruit curd without curdling requires moderate heat and continuous movement. Whisking whole eggs together with extra yolks produces a sturdy emulsion that sets firmly once chilled. Using a double boiler provides a protective buffer against scorching. Keep your thermometer handy to ensure the curd reaches 160°F (71°C), which both guarantees food safety and fully activates the thickening properties of the egg proteins. Whisking in cold or softened butter off the heat rounds out the intense acidity and imparts a glossy, sliceable sheen.
Constructing an Even Shortbread Crust
The foundation of this slice relies on a classic shortbread formula enriched with desiccated coconut. Chilled butter cut finely into the dry ingredients prevents excessive gluten development, yielding a tender, crumbly bite that holds cleanly against the soft fruit topping. Pressing the mixture firmly and uniformly across the pan eliminates air pockets that could cause the curd to seep beneath the crust during assembly. Pre-baking until faintly golden establishes structural rigidity, ensuring the bottom stays crisp even after days of refrigeration.
Slicing and Texture Preservation
Texture is central to the appeal of this slice, from the crunchy toasted coconut garnish to the silky curd and sandy shortbread. Toasting the coconut flakes in a dry skillet brings out natural oils and enhances crispness. Add the toasted flakes directly after pouring the warm curd so they adhere without becoming soggy. Thorough chilling for at least three hours is mandatory before cutting. Use the parchment paper wings to lift the slab cleanly onto a board before dividing into even portions.
Before you start
For the cleanest presentation, wipe your chef's knife with a warm, damp cloth between each cut. If using fresh passion fruit, strain the pulp through a fine-mesh sieve while pressing firmly with the back of a spoon to extract maximum juice without dragging tough black seeds into the curd. Keep the heat under your double boiler gentle to prevent the eggs from scrambling before they thicken properly.
THE RECIPE
Passion Fruit Coconut Slice
16 servings · 25 minutes preparation · 30 minutes cooking · 240 minutes cooling, chilling or resting
Ingredients
Step-by-step instructions
- Preheat the oven to 350°F (175°C) and line an 8x8-inch square metal baking pan with parchment paper, leaving an overhang on two sides for lifting.
- Combine the all-purpose flour, powdered sugar, and desiccated coconut in a bowl, then rub in the 125 grams of chilled butter until fine crumbs form; press firmly into the prepared pan in an even layer.
- Bake the shortbread base at 350°F (175°C) for 15 minutes until light golden around the edges, then remove to a wire rack to cool slightly for 30 minutes.
- In a heatproof bowl set over a pot of simmering water, whisk together the passion fruit pulp, whole eggs, egg yolks, granulated sugar, and lemon juice continuously until thick and the mixture registers 160°F (71°C) on an instant-read thermometer, roughly 8 to 10 minutes.
- Remove the curd from heat, whisk in the 80 grams of softened butter piece by piece until fully melted and glossy, then pour the warm curd immediately over the pre-baked shortbread base.
- Spread flaked coconut across a dry skillet over medium-low heat for 3 to 5 minutes, stirring constantly until fragrant and pale golden; immediately scatter evenly over the passion fruit layer.
- Allow the slice to cool at room temperature for 30 minutes, then transfer to the refrigerator to chill thoroughly for at least 3 hours (180 minutes) until set before slicing into 16 squares.
Kitchen notes

Storage & make-ahead
Store cut bars in an airtight container in the refrigerator for up to 4 days, ensuring they are chilled promptly within 2 hours of serving. Separate layers with parchment paper to prevent sticking. Freezing is not recommended as curd can release water upon thawing.

Frequently asked questions
Can I use frozen passion fruit puree instead of fresh fruit?
Yes, 100 percent unsweetened frozen passion fruit puree works reliably. Thaw it completely in the refrigerator and measure accurately. If the thawed puree contains excess seeds, strain it through a fine-mesh sieve to ensure a silky curd texture.
Why did my passion fruit curd fail to set firmly?
A runny curd typically results from undercooking or insufficient chilling. The curd must reach 160°F (71°C) on the stovetop to thicken the egg proteins properly, and it requires at least three hours in the refrigerator to solidify completely.
Can I substitute sweetened shredded coconut for the topping?
Unsweetened flaked coconut is strongly preferred. Sweetened coconut burns rapidly in the skillet and can add excessive sugar to a recipe already balanced by the rich curd and shortbread crust.
