Ingredients for Australian Chocolate Coconut Crunch

- 1 cup (90g) desiccated coconut: Adds a chewy texture and delicious coconut flavor.
- 125g (½ cup) unsalted butter: Helps bind the ingredients and creates a rich base.
- ½ cup (110g) caster sugar: Sweetens the chocolate mixture. Granulated sugar can also be used.
- 2 tablespoons unsweetened cocoa powder: Gives the base its deep chocolate flavor.
- 1 large egg, lightly beaten: Helps bind the mixture. Use pasteurized egg if preferred.
For the Chocolate Topping
- 200g (7 oz) dark chocolate: Finely chopped dark chocolate or good-quality chocolate chips.
- 1 tablespoon vegetable oil or coconut oil: Helps create a smooth, glossy topping that is easier to slice.
Optional Add-Ins

Essential Equipment
- 20cm x 20cm (8-inch x 8-inch) square baking tin.
- Baking paper.
- Large saucepan.
- Mixing bowls.
- Spatula or wooden spoon.
- Food processor or zip-top bag and rolling pin.

How to Make Australian Chocolate Coconut Crunch
Step 1: Prepare the Pan and Crush the Biscuits
Line an 8-inch (20cm) square pan with baking paper, leaving some overhang on two opposite sides. This makes it easier to lift the finished slice out of the pan.
Place the plain sweet biscuits in a food processor and pulse until they form fine crumbs. If you don’t have a food processor, put the biscuits in a sturdy zip-top bag and crush them with a rolling pin.
Transfer the crumbs to a large mixing bowl and set aside.
Step 2: Toast the Coconut
Toasting the coconut is optional, but it adds a wonderful nutty aroma and deeper flavor.
Place the desiccated coconut in a dry frying pan over medium heat. Stir constantly for approximately 2–4 minutes until it becomes lightly golden.
Transfer the toasted coconut to a bowl immediately so it doesn’t continue cooking in the hot pan.
Step 3: Prepare the Chocolate Butter Mixture
Place the butter in a large saucepan over low heat and allow it to melt completely.
Add the caster sugar and cocoa powder. Stir continuously until the mixture becomes smooth and the sugar begins to dissolve.
Remove the saucepan from the heat and allow the mixture to cool slightly.
Slowly add the lightly beaten egg while whisking continuously. This helps prevent the egg from scrambling.
Return the saucepan to low heat and stir constantly until the mixture reaches 160°F (71°C) on a food thermometer. Keep stirring to prevent the mixture from sticking to the bottom.
Food safety note: Do not rely on cooking time alone to determine whether the egg is safe. If you cannot verify the temperature, use pasteurized egg or a suitable pasteurized egg product.
Step 4: Combine the Biscuit Crumbs and Coconut
Remove the saucepan from the heat.
Add the crushed biscuits and toasted coconut to the chocolate mixture. Stir thoroughly until all the crumbs are coated in the rich chocolate butter mixture.
If you’re using chopped walnuts, pecans, or raisins, fold them in at this stage.
The mixture should look evenly coated and hold together when pressed between your fingers.
Step 5: Press the Base into the Pan
Transfer the chocolate coconut mixture into the prepared square pan.
Use the back of a spoon or a flat-bottomed glass to press the mixture firmly into an even layer.
Pay particular attention to the corners and edges. A firmly packed base helps the finished squares hold together when sliced.
Place the pan in the refrigerator while preparing the chocolate topping.
Step 6: Melt the Dark Chocolate Topping
Place the chopped dark chocolate and vegetable or coconut oil in a heatproof bowl.
Set the bowl over a saucepan of gently simmering water, making sure the bottom of the bowl doesn’t touch the water.
Stir gently until the chocolate is completely melted and smooth.
Alternatively, microwave the chocolate and oil in 20-second intervals, stirring between each interval until melted.
Step 7: Add the Chocolate Layer
Remove the chilled biscuit base from the refrigerator.
Pour the melted chocolate over the base and spread it evenly with a spatula.
If desired, sprinkle a little extra toasted coconut over the chocolate before it begins to set.
Step 8: Chill Until Firm
Return the pan to the refrigerator for at least 3–4 hours, or preferably overnight.
The chilling time allows the biscuit base to firm up and the chocolate topping to become solid enough for clean slicing.
Step 9: Slice and Serve
Once completely set, use the parchment paper overhang to lift the slice out of the pan.
Place it on a cutting board and use a large, sharp knife to cut it into approximately 16 squares.
For cleaner cuts, dip the knife in hot water and wipe it dry between slices.
Serve chilled with tea, coffee, or a glass of milk.
Expert Tips for the Best Chocolate Coconut Crunch
Use Fine Biscuit Crumbs
Smaller, evenly crushed biscuit pieces help the base hold together. Avoid leaving large chunks, as they can make slicing more difficult.
Toast the Coconut Carefully
Desiccated coconut can brown very quickly. Stir constantly and remove it from the pan as soon as it becomes lightly golden.
Pack the Base Firmly
Pressing the mixture firmly into the pan is one of the most important steps. A loosely packed base may crumble when cut into squares.
Choose Good-Quality Chocolate
Dark chocolate balances the sweetness of the biscuit and coconut base. Choose a chocolate you enjoy eating on its own.
Allow Enough Chilling Time
Don’t rush the setting process. A fully chilled slice is easier to remove from the pan and produces neater portions.
Delicious Variations to Try
Chocolate Coconut Crunch with Almonds
Add ¼ cup of chopped almonds to the biscuit mixture for an extra crunchy texture. Toasting the almonds briefly before adding them can bring out their nutty flavor.
Chocolate Coconut Raisin Slice
Fold 2 tablespoons of raisins or sultanas into the base for little bursts of sweetness in every bite.
Dark Chocolate Coconut Crunch
Use dark chocolate with a higher cocoa percentage for a deeper, less sweet chocolate flavor.
Extra Coconut Chocolate Slice
Increase the coconut flavor by sprinkling toasted coconut over the melted chocolate topping before chilling.
How to Store Australian Chocolate Coconut Crunch
Place the finished squares in an airtight container and keep them refrigerated.
They can be stored in the refrigerator for up to 1 week. Keeping them chilled helps the chocolate topping remain firm and preserves the texture of the base.
Can You Freeze Chocolate Coconut Crunch?
Yes. Arrange the squares in a freezer-safe container, separating the layers with baking paper to prevent sticking.
Freeze for up to 3 months for the best quality. Thaw the portions in the refrigerator before serving.
Frequently Asked Questions
Is Australian Chocolate Coconut Crunch a no-bake dessert?
Yes. This version does not require an oven. The biscuit and coconut base is combined with a warm chocolate mixture, pressed into a pan, topped with melted chocolate, and chilled until firm.
What biscuits are best for chocolate coconut crunch?
Plain sweet biscuits such as Marie biscuits are excellent choices. Graham crackers also work well and provide a slightly different flavor.
Can I use sweetened shredded coconut instead of desiccated coconut?
You can, but the texture and sweetness may change. Desiccated coconut is finer and absorbs the chocolate mixture more evenly, making it the better choice for this recipe.
Why is my chocolate coconut slice falling apart?
The mixture may not have been pressed firmly enough into the pan, or it may need more chilling time. Make sure the base is compact and completely set before slicing.
How do I get clean chocolate slices?
Use a sharp knife warmed under hot water. Wipe it dry between cuts to prevent the chocolate topping from cracking or sticking to the blade.
Can I use milk chocolate instead of dark chocolate?
Yes. Milk chocolate creates a sweeter topping, while dark chocolate provides a richer flavor and balances the sweetness of the base.
Can I make this chocolate coconut dessert ahead of time?
Absolutely. Prepare the slice the day before serving and leave it covered in the refrigerator overnight. Cut it into squares shortly before serving.
