How to Make Classic Australian Chocolate Slice
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Grease and line an 8×8-inch (20×20 cm) square baking pan with parchment paper, leaving a little paper over the sides. This makes it much easier to remove the slice once it has cooled.
Step 2: Combine the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking powder, salt, and sugar.
Breaking up any lumps in the cocoa powder at this stage will help create a smoother chocolate mixture.
Step 3: Add the Wet Ingredients
In a separate bowl, whisk together the melted butter, eggs, vanilla extract, and milk.
Pour the wet mixture into the dry ingredients.
Stir gently with a spatula or wooden spoon until everything is just combined. Don’t overmix the batter, as this can make the finished slice unnecessarily dense.
Step 4: Transfer to the Pan
Spread the chocolate batter evenly into the prepared baking pan.
Use the back of a spatula to smooth the surface.
Step 5: Bake
Place the pan in the preheated oven and bake for approximately 20–25 minutes.
The center should be set, while a toothpick inserted into the middle should come out with a few moist crumbs attached.
Avoid overbaking the slice. You want it to remain soft and slightly fudgy rather than dry.
Step 6: Cool Completely
Remove the slice from the oven and allow it to cool in the pan for about 10 minutes.
Transfer it to a wire rack and allow it to cool completely before adding the icing.
Cooling is important because warm chocolate slice can cause the icing to melt and become too thin.
How to Make the Chocolate Icing
Place the powdered sugar and cocoa powder in a bowl and whisk to remove any lumps.
Add the melted butter and vanilla extract.
Gradually add the warm milk, one tablespoon at a time, stirring until you have a thick but spreadable chocolate icing.
If the icing is too thick, add another small splash of milk. If it becomes too thin, add a little more powdered sugar.
Spread the icing evenly over the cooled chocolate slice.
While the icing is still soft, sprinkle shredded coconut or chocolate sprinkles over the top if desired.
Allow the icing to set for about 20–30 minutes before cutting.
How to Cut Chocolate Slice
For neat squares, use a sharp knife and cut the slice into 12–16 pieces.
For clean cuts, wipe the knife between slices. You can also chill the finished slice for 20 minutes before cutting if you prefer firmer pieces.
Small squares are ideal for afternoon tea or parties because the chocolate flavor is rich enough that you don’t need a large serving.
Tips for the Best Chocolate Slice
Measure the flour correctly. Too much flour can make the slice dry. For the most consistent results, weigh the flour if you have a kitchen scale.
Don’t overbake. The slice should remain soft in the middle. A few moist crumbs on a toothpick are a good indication that it is ready.
Use good-quality cocoa powder. Cocoa is one of the main flavors in this recipe, so a good unsweetened cocoa powder can make a noticeable difference.
Cool before icing. Make sure the base is completely cool before spreading the chocolate icing over it.
Don’t make the icing too thin. Add the milk gradually so you can control the consistency.
What to Serve With Chocolate Slice
This classic Australian dessert recipe is particularly delicious with a hot drink.
Serve it alongside:
- Freshly brewed coffee
- Black tea
- English breakfast tea
- Hot chocolate
- A glass of cold milk
For a dessert platter, cut the slice into small squares and serve it with fresh berries, strawberries, or raspberries.
Can I Make Chocolate Slice Ahead of Time?
Absolutely. This recipe is ideal for making ahead because the flavor and texture remain delicious after resting.
You can bake the slice a day before serving and keep it covered at room temperature. Add the icing after the slice has cooled completely.
This makes it a convenient make-ahead dessert for parties, afternoon tea, or bake sales.
How to Store Australian Chocolate Slice
Store the finished chocolate slice in an airtight container.
It can be kept at room temperature for approximately 3 days. For a firmer texture, you can refrigerate it for up to 5 days.
If refrigerated, allow the slice to sit at room temperature for several minutes before serving.
You can also freeze the un-iced chocolate base for up to 2 months. Thaw it completely before adding fresh icing.
Easy Variations
Coconut Chocolate Slice
Add 1/2 cup (40 g) shredded coconut to the chocolate batter for extra texture and coconut flavor.
Chocolate Chip Slice
Fold 1/2 cup (85 g) chocolate chips into the batter before baking.
Double Chocolate Slice
Add extra chocolate chips to the batter and finish the iced slice with a light drizzle of melted chocolate.
Nutty Chocolate Slice
Add 1/2 cup (60 g) chopped walnuts or pecans to the batter for a crunchy variation.
Frequently Asked Questions
Is Australian chocolate slice the same as brownies?
Not exactly. Australian chocolate slice has similarities to brownies, but the texture is usually lighter and more cake-like. It is traditionally finished with chocolate icing rather than served simply as a fudgy brownie.
Can I use salted butter?
Yes. If using salted butter, you can reduce or omit the additional salt in the recipe.
Can I make this recipe without icing?
Yes. The chocolate slice is delicious on its own, although the chocolate icing gives it the classic sweet finish.
Why did my slice turn out dry?
The most common reasons are overbaking or using too much flour. Start checking the slice around 20 minutes and remove it when a toothpick comes out with a few moist crumbs.
Can I use a larger baking pan?
Yes, but the slice will be thinner and will likely require less baking time. Keep an eye on it toward the end of cooking.
