If you’re looking for a chocolate slice from down under that’s practically foolproof, this Australian classic is about to become your new go-to. It comes together with ingredients you already have in your pantry, and the whole thing bakes in under half an hour.
This isn’t a fussy dessert, it’s the kind of straightforward bar that generations of Australian families have loved. The base is soft and chocolatey with a whisper of coconut, and the magic happens when you pour warm icing over the hot bars straight from the oven.
What I love most is how forgiving it is. No rolling, no piping, no stress. Just mix, press, bake, and frost. You’ll have a batch of rich, glossy chocolate bars ready to share in about an hour from start to finish.
The Ingredient Lineup
This recipe uses simple pantry staples split into two parts: the chocolate base and the silky icing. Everything mixes by hand in just a couple of bowls, so there’s minimal cleanup.
- All-purpose flour: Forms the structure of the base layer and keeps the bars from being too dense or crumbly.
- Desiccated coconut: Adds subtle texture and a hint of tropical flavor without making the bars taste like coconut cake.
- Brown sugar: Brings warmth and moisture to the base, making the bars tender rather than tough.
- Cocoa powder: The star of the show, use unsweetened so you control the sweetness level.
- Melted butter: Binds everything together and adds richness; cooling it slightly before mixing prevents the egg from cooking.
- Powdered sugar and boiling water: Create a glossy icing that sets up smooth and shiny as it cools on top of the warm bars.
How I Make Chocolate Slice from Down Under
Here’s how to build these bars from scratch:
Step 1: Prep Your Pan
Heat your oven to 325°F and line a 9-by-9-inch baking dish with parchment paper, then give the paper a light grease. This keeps the bars from sticking and makes them easy to lift out once they’re cool.
Step 2: Mix the Base
In a medium bowl, whisk together the flour, coconut, brown sugar, and cocoa powder until evenly combined. Then stir in the egg, cooled melted butter, and vanilla until just mixed, don’t overstir or the bars will be tough.
Step 3: Press and Bake
Transfer the mixture to your prepared pan and press it into an even, compact layer using the back of a spoon or your hands. Bake for 20 to 23 minutes, until the center feels set when you gently touch it.
Step 4: Make the Icing
About 5 minutes before the bars finish baking, sift the powdered sugar and cocoa powder together in a clean bowl. Stir in the melted butter and boiling water until you have a smooth, pourable consistency.
Step 5: Frost While Hot
Pour the warm icing over the hot bars and quickly spread it to the edges with a spatula or the back of a spoon. The heat helps it spread smoothly and sink slightly into the surface.
Step 6: Cool and Slice
Let the bars cool completely at room temperature until the icing is set and firm, this usually takes 1 to 2 hours. Then slice into 9 to 12 pieces with a sharp knife, wiping the blade between cuts for clean edges.
Make-Ahead, Storage & Leftovers
Store
Keep the bars in an airtight container at room temperature for up to 5 days. They actually taste better the next day once the flavors have settled.
Freeze
Wrap individual bars in plastic wrap and freeze for up to 2 months. Thaw at room temperature for about 30 minutes before serving.

Recipe FAQs
Can I make these in a different pan size?
Yes, but adjust your baking time. An 8-by-8-inch pan will give you thicker bars and may need 2 to 3 extra minutes. A 9-by-13-inch pan will give you thinner bars and may bake 2 to 3 minutes faster.
What if my icing is lumpy?
Sift the powdered sugar and cocoa powder together before mixing with the butter and water. If you still have lumps, strain the icing through a fine-mesh sieve.
Can I skip the coconut?
Absolutely. Replace it with an extra 1 cup of flour, or use chopped nuts, crushed biscuits, or even leave it out entirely. The bars will be slightly denser but still delicious.
Why is my icing too thick to spread?
The boiling water is key to getting the right consistency. Add it slowly and stir well. If it’s still too thick, add a bit more hot water, one teaspoon at a time.

Pro Tips for Success
- Make sure your butter is cooled before mixing it with the egg, or you’ll end up with scrambled bits in your batter.
- Don’t skip the parchment paper, it makes lifting the whole slab out of the pan so much easier.
- Pour the icing while the bars are still hot; this is what gives you that smooth, glossy finish.
- If your icing is too thick to pour, add a splash more boiling water, one teaspoon at a time.
- For extra-clean slices, dip your knife in hot water and wipe it dry between cuts.
