These classic Aussie biscuits form the buttery base. Digestives or graham crackers work as substitutes.

For texture and a subtle tropical note.
150 g red and green glacé cherries, halved
Brings festive color and fruity bursts.
½ cup dried cranberries (optional)
Adds tartness and depth.
100 g Turkish delight or nougat, chopped (optional)
For a chewy, candy-like surprise.

Sweet Binder

1 can (395 g) sweetened condensed milk
The rich, sticky glue that holds it all together.
125 g unsalted butter
Adds richness and helps bind the slice.
1 teaspoon vanilla extract
Enhances the flavor with a warm, sweet aroma.

Topping (Optional but Highly Recommended)

150 g white chocolate, melted
A creamy, snowy finish.
Extra glacé cherries, halved
For garnish and extra color.
Crushed pistachios
Adds crunch and a festive green hue.
Christmas sprinkles

Equipment You’ll Need

20 × 20 cm slice tin
Baking paper
Large mixing bowl
Saucepan
Spatula
Measuring cups and spoons
Sharp knife
Small offset spatula (optional for spreading chocolate)

Step-by-Step Instructions

Step 1: Prepare the Tin

Line a 20 × 20 cm slice tin with baking paper, leaving an overhang on all sides. This makes it easy to lift the slice out once it’s set.

Tip: Lightly grease the tin before lining to help the paper stick in place.

Step 2: Combine the Dry Ingredients

In a large mixing bowl, combine:

250 g crushed biscuits
1 cup mini marshmallows
1 cup desiccated coconut
150 g halved glacé cherries
½ cup dried cranberries (if using)
100 g chopped Turkish delight or nougat (if using)

Toss everything together until evenly distributed. The colors should look bright and festive.

Tip: Don’t crush the biscuits too finely—you want a mix of crumbs and small chunks for texture.

Step 3: Make the Sweet Binder

In a small saucepan over low heat, melt:

125 g unsalted butter

Once melted, add:

1 can sweetened condensed milk
1 teaspoon vanilla extract

Stir gently until the mixture is smooth and warmed through. Do not boil—just heat until everything is combined.

Tip: Stir constantly to prevent scorching.

Step 4: Mix and Press

Pour the warm condensed milk mixture over the dry ingredients.

Working quickly, fold everything together with a spatula until well coated and sticky.

Transfer the mixture to the prepared tin and press down firmly with a spatula or the back of a spoon to create an even layer.

Tip: Use a piece of baking paper on top to press down without sticking.

Step 5: Add the Festive Topping

Pour the melted white chocolate over the top of the slice and spread evenly.

While the chocolate is still soft, decorate with:

Extra glacé cherries
Crushed pistachios
Christmas sprinkles

Get creative—this is your chance to make it sparkle!

Step 6: Chill and Slice

Refrigerate the slice for 2–3 hours, or until firm.

Once set, lift it out of the tin using the baking paper overhang.

Use a sharp knife warmed under hot water to cut into squares or bars.

Tip: Wipe the knife clean between cuts for neat edges

To Serve

This slice is perfect for:

Christmas dessert platters
Holiday gift boxes
School or office parties
Festive afternoon teas
No-bake treat swaps

Serve chilled or at room temperature for the best texture.

Tips for Success

Press firmly: This helps the slice hold together and prevents crumbling.
Customize the mix-ins: Add chopped nuts, crushed candy canes, or mini M&Ms.
Swap the chocolate: Use milk or dark chocolate for a richer topping.
Add a minty twist: Stir in ½ teaspoon peppermint extract to the binder.
Make ahead: Keeps for 1 week in the fridge or 2 months in the freezer.

Variations to Try

Tropical Slice: Add dried pineapple, mango, and macadamias.
Chocolate Cherry Slice: Use chocolate biscuits and drizzle with dark chocolate.
Nut-Free Version: Skip pistachios and use sprinkles or crushed candy canes.
Vegan Option: Use plant-based condensed milk, vegan butter, and dairy-free chocolate.
