Ingredients
- 1 cup (125 g) all-purpose flour
- 1 cup (200 g) granulated sugar
- ½ cup (50 g) unsweetened cocoa powder
- ½ cup (125 g) unsalted butter, melted
- 1 large egg
- ½ cup (120 ml) milk
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- Pinch of salt
For the Chocolate Icing
- 1 cup (120 g) powdered sugar
- 2 tablespoons cocoa powder
- 2 tablespoons butter, melted
- 2 tablespoons milk
- ½ teaspoon vanilla extract
- Sprinkles or shredded coconut for topping (optional)
Step-by-Step Instructions
Step 1: Preheat and prepare the pan
Preheat your oven to 180°C (350°F). Line a square baking pan (about 20×20 cm / 8×8 inch) with baking paper or lightly grease it.
Step 2: Mix the dry ingredients
In a large bowl, combine the flour, sugar, cocoa powder, baking powder, and salt.
Step 3: Add the wet ingredients
Add the melted butter, egg, milk, and vanilla to the bowl. Mix until you get a smooth, thick chocolate batter.
Step 4: Bake the slice
Pour the batter into the prepared pan and spread it evenly. Bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out mostly clean.
Step 5: Prepare the icing
While the slice is baking, mix the powdered sugar, cocoa, melted butter, milk, and vanilla in a bowl until smooth and glossy.
Step 6: Ice while warm
As soon as the slice comes out of the oven, spread the icing over the warm cake. Add sprinkles or coconut if you like.
Step 7: Cool and cut
Let it cool completely in the pan, then cut into squares.
Serving Ideas
Serve Australian Chocolate Slice with tea, coffee, or a cold glass of milk. It’s perfect for lunchboxes, dessert tables, or a quick sweet snack.
You can also warm a slice slightly and serve it with vanilla ice cream.
Why This Recipe Works
The cocoa and sugar give deep chocolate flavor, while butter and milk keep the slice soft and moist. Icing it while warm lets the topping melt slightly into the cake, making every bite extra rich.
It’s fast, simple, and always a crowd-pleaser.
Final Thoughts
Australian Chocolate Slice is a true classic. It’s easy to make, uses basic ingredients, and delivers big chocolate flavor in every bite.
Once you bake it, it will become one of your go-to chocolate treats.
