Equipment Needed
Creating this stunning passionfruit slice requires some basic kitchen equipment that most home bakers already have on hand. We recommend gathering all your tools before starting to ensure smooth preparation from base to topping.
Essential Baking Equipment:
- 8-inch square baking tin for the perfect slice dimensions
- Stand mixer or large bowl with electric beater for effortless mixing
- Medium bowl and balloon whisk for combining wet ingredients
- Small saucepan and spatula for heating components
Preparation Tools:
- Sharp knife or cookie cutter for clean slicing
- Measuring cups and spoons for accurate portions
- Rubber spatula for scraping bowls clean
- Wire cooling rack for proper setting
Optional but Helpful:
- Parchment paper for easy removal
- Fine mesh sieve for smooth filling texture
- Kitchen scale for precise measurements
The stand mixer makes quick work of creating our buttery shortbread base while the balloon whisk ensures our passionfruit filling achieves the perfect consistency. A small saucepan becomes essential if you choose to add our optional passionfruit jelly topping. The 8-inch square tin provides ideal proportions for serving generous slices that showcase the beautiful layers of this Australian inspired dessert.
Having sharp cutting tools ready ensures clean presentation when serving. We find that preparing all equipment beforehand allows us to focus on technique rather than searching for tools mid-recipe.
Instructions
Now we’ll walk through each step to create our perfect passionfruit slice. These instructions will guide you through building the base and creating that signature tangy topping.
Step 1: Prepare the Base
We begin by preheating our oven to 180°C (350°F) or 160°C (320°F) for fan-forced ovens. Line our 8-inch square baking tin with parchment paper for easy removal later.
In a large bowl, we combine 1 cup self-raising flour, ½ cup caster sugar, 1 cup desiccated coconut, and 150g melted butter. Mix these ingredients until they form a cohesive dough that holds together when pressed.
Press this mixture firmly into our prepared baking tin, creating an even layer across the bottom. We want to ensure the base is compact and level for consistent baking.
Bake the base for 10-12 minutes until it becomes lightly golden around the edges. Remove from the oven and set aside to cool while we prepare our filling.
Step 2: Make the Passionfruit Filling
In a clean medium bowl, we whisk together our sweetened condensed milk, lemon juice, and passionfruit pulp until the mixture is smooth and well combined. The filling should have a vibrant yellow color and smooth consistency.
Beat the mixture thoroughly to ensure all ingredients are fully incorporated. This creates the creamy, tangy layer that makes our slice irresistible.
Step 3: Assemble the Slice
Once our base has cooled slightly, we pour the passionfruit filling evenly over the baked base. Use a spatula to spread the filling to all corners, ensuring complete coverage.
Gently tap the tin on the counter to eliminate any air bubbles and create a smooth surface. The filling should sit evenly across the entire base without gaps.
Step 4: Bake and Cool
We reduce our oven temperature to 150°C (300°F) and return the slice to bake for 15 minutes. The filling is ready when it feels set but still slightly soft when lightly touched in the center.
Remove from the oven and allow the slice to cool completely in the tin before cutting. This cooling period lets the filling firm up properly, making clean cuts possible when we slice into squares for serving.
Directions for Serving
We recommend serving our passionfruit slice chilled for the best texture and flavor experience. Remove the slice from the refrigerator about 10 minutes before serving to allow it to reach the ideal temperature that balances the creamy filling with the crisp base.
Cut the slice into neat squares using a sharp knife that has been wiped clean between cuts. This technique ensures each piece maintains its beautiful layers and prevents the filling from smearing across the base. We find that cutting into 16 equal squares provides the perfect portion size for most occasions.
Dust each square lightly with powdered sugar just before serving to enhance the visual appeal and add a subtle sweetness that complements the tangy passionfruit flavor. Fresh passionfruit pulp drizzled over individual pieces creates an elegant garnish that intensifies the tropical taste.
Fresh mint leaves make an excellent decorative touch that adds a pop of color and a refreshing aroma to each serving. Place one or two small leaves on top of each square or arrange them around the serving plate for a professional presentation.
Our passionfruit slice pairs beautifully with a dollop of whipped cream or vanilla ice cream for those who prefer a richer dessert experience. The cool creaminess balances the tartness of the passionfruit while adding textural contrast to each bite.
Serve the slice on chilled plates to maintain the optimal temperature and prevent the filling from becoming too soft. We suggest offering small dessert forks alongside each portion to make eating more comfortable and elegant for your guests.
The slice maintains its quality when served at room temperature as well, making it versatile for outdoor gatherings or picnics where refrigeration may not be readily available.
Storage Tips
We recommend storing our finished passionfruit slice properly to maintain its delicious flavor and texture. Refrigeration works best for short-term storage needs.
Refrigeration Storage
Our passionfruit slice stays fresh in an airtight container in the refrigerator for optimal results. We can store it safely for up to one week when properly sealed. Some recipes suggest a shorter timeframe of up to 5 days for peak quality.
| Storage Method | Duration | Container Type |
|---|---|---|
| Refrigeration | Up to 1 week | Airtight container |
| Alternative refrigeration | Up to 5 days | Airtight container |
Freezing Options
We can freeze our passionfruit slice for longer storage periods. Cut the slice into individual squares first. Wrap each square individually before placing them in the freezer. Our frozen slices maintain quality for up to 3 months.
When we’re ready to serve frozen slices we should thaw them in the refrigerator overnight. This gradual thawing process preserves the texture and prevents condensation from affecting the slice.
But some recipes advise against freezing due to potential texture changes that may occur during the freezing and thawing process.
Passionfruit Pulp Storage
We can extend our passionfruit enjoyment by storing extra pulp properly. Fresh passionfruit pulp freezes well in ice cube trays for up to three months. Simply defrost the frozen cubes and stir before using in our baking projects.
Whole passionfruits store at room temperature for approximately 2 weeks. We can extend their life by refrigerating whole fruits for up to one month. This prevents dehydration and maintains the fruit’s quality for future use.
Make-Ahead Instructions
We love how flexible this passionfruit slice recipe is for busy schedules and special occasions. Planning ahead becomes effortless when you understand the optimal timing for each preparation stage.
Advance Preparation Timeline
| Timeframe | Preparation Method | Storage Instructions |
|---|---|---|
| 1-2 days ahead | Complete recipe | Refrigerate in airtight container |
| 3-5 days ahead | Bake base only | Wrap tightly and refrigerate |
| Up to 1 week | Full recipe | Store covered in refrigerator |
| Up to 3 months | Complete slices | Freeze individually wrapped |
Base Preparation in Advance
We recommend preparing the shortbread base up to three days before your event. Press the dough into your lined baking tin and bake until golden as directed. Allow the base to cool completely before covering tightly with plastic wrap or foil. Store the prepared base in the refrigerator until you’re ready to add the passionfruit filling.
Complete Make Ahead Assembly
For maximum convenience we suggest making the entire passionfruit slice 24 to 48 hours before serving. This approach allows the flavors to meld beautifully while the texture reaches its optimal consistency. After the final baking step and complete cooling cover the slice with plastic wrap or transfer to an airtight container. Refrigerate until needed then remove 10 minutes before cutting and serving.
Passionfruit Pulp Preparation
We always prepare extra passionfruit pulp when the fruit is in season. Scoop the pulp from fresh passionfruits and freeze in ice cube trays for perfectly portioned amounts. Once frozen transfer the cubes to freezer bags where they’ll maintain quality for up to three months. This method ensures you can make our passionfruit slice year round without compromising on flavor.
Freezing for Long Term Storage
Our freezing method works exceptionally well for this recipe. Cut the completely cooled slice into individual portions and wrap each square in plastic wrap followed by aluminum foil. Label with the date and freeze for up to three months. When ready to serve thaw overnight in the refrigerator maintaining the slice’s creamy texture and vibrant taste.
Variations and Substitutions
Our passionfruit slice recipe adapts beautifully to different dietary needs and preferences. We can transform this classic dessert into versions that suit gluten-free, dairy-free, paleo, or vegan lifestyles while maintaining its signature tangy-sweet flavor profile.
Base Variations
Baked Shortbread Base Options
We recommend staying with our original flour-based shortbread for the most authentic texture. But, gluten-free flour blends work exceptionally well as direct substitutions. Almond flour creates a nutty, tender base that pairs beautifully with passionfruit’s tropical notes.
No-Bake Biscuit Alternative
For those seeking convenience, we can create a no-bake base using crushed Scotch Finger biscuits. Combine 2 cups of finely crushed biscuits with 1/2 cup desiccated coconut and 1/3 cup melted butter. Press this mixture firmly into our lined tin and chill for 30 minutes before adding the filling.
Paleo and Coconut Flour Bases
Coconut flour offers another excellent alternative, though we need to adjust liquid ratios. Use 3/4 cup coconut flour in place of regular flour and add an extra egg yolk to bind the mixture properly.
Topping and Filling Substitutions
Dairy-Free Adaptations
Coconut cream provides an excellent substitute for our condensed milk filling. We mix 1 can of full-fat coconut cream with 1/3 cup powdered sugar and our passionfruit pulp. This creates a similarly rich, creamy texture with tropical undertones.
Sugar-Free Options
Coconut sugar works wonderfully in both base and filling, providing subtle caramel notes. We can also use honey or maple syrup, reducing other liquid ingredients by 2 tablespoons when making these substitutions.
Alternative Icing Toppings
Some variations replace our condensed milk filling with a traditional icing. We combine 2 cups powdered sugar, 1/4 cup softened butter, and 1/3 cup passionfruit pulp. Add milk one tablespoon at a time until we achieve spreading consistency.
Dietary Restriction Accommodations
| Dietary Need | Base Substitution | Filling Alternative | Key Considerations |
|---|---|---|---|
| Gluten-Free | Gluten-free flour blend | Same condensed milk filling | Use 1:1 ratio replacement |
| Dairy-Free | Coconut oil for butter | Coconut cream + powdered sugar | Chill coconut cream beforehand |
| Paleo | Almond flour + coconut flour | Collagen + natural sweeteners | Adjust liquid ratios |
| Vegan | Coconut oil + plant milk | Cashew cream + agave | Soak cashews 4 hours |
Healthier Alternatives
We can reduce refined sugar by using dates in our base mixture. Blend 1 cup pitted dates with 1/4 cup water until smooth, then incorporate into our flour mixture. This natural sweetener complements passionfruit’s acidity perfectly.
Texture Modifications
Adding 1/4 cup desiccated coconut to our base creates delightful textural contrast. We can also incorporate chopped macadamia nuts or toasted almonds for extra crunch and flavor depth.
Fruit Variations
While passionfruit remains our star ingredient, we can blend it with other tropical fruits. Mango puree mixed with passionfruit creates a smoother, mellower flavor. Lime zest and juice intensify the citrus notes for those who prefer extra tartness.
These adaptations ensure our passionfruit slice remains accessible to various dietary preferences while preserving the dessert’s beloved characteristics. Each variation maintains the perfect balance between sweet base and tangy topping that makes this treat so irresistible.
