Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the slice base
1 cup milk or dark chocolate, chopped (150 grams)
100 grams butter
395 grams sweetened condensed milk
250 grams plain sweet biscuits, roughly crushed
½ cup desiccated coconut (40 grams)
2 tablespoons cocoa powder
1 cup Maltesers, halved

For the chocolate topping
1 ½ cups milk or dark chocolate, chopped (225 grams)
1 teaspoon vegetable oil

Directions

Line a 25 cm square slice tin with baking paper, lightly greasing the tin first so the paper sticks well. Set aside.

Place the biscuits in a food processor and pulse until roughly crushed. You want a mixture of small chunks and crumbs rather than a fine powder. Set aside.

Carefully halve the Maltesers using a sharp knife and gentle pressure. Set aside.

In a large saucepan over low heat, combine the chocolate, butter, and sweetened condensed milk. Stir frequently until the butter is fully melted and the mixture is smooth and well combined.

Remove the saucepan from the heat and allow the mixture to cool for about 5 minutes. This helps prevent the Maltesers from melting too much when added.

Add the crushed biscuits, desiccated coconut, cocoa powder, and halved Maltesers to the saucepan. Mix thoroughly until everything is evenly coated.

Press the mixture firmly into the prepared tin, smoothing the top with the back of a spoon. Refrigerate for 30 minutes to set slightly.

To make the topping, melt the chocolate in a microwave-safe bowl in 30-second bursts, stirring between each burst until smooth. Stir in the vegetable oil.

Pour the melted chocolate over the chilled base and spread evenly. Gently tap the tin on the bench to level the topping. If desired, decorate the top with extra Maltesers.

Return the slice to the refrigerator for several hours, or until fully set, before slicing.

Variations

You can swap the Maltesers for other chocolate-coated candies or leave them out entirely for a classic chocolate no-bake slice. Dark chocolate can be used throughout for a less sweet, more intense flavour. Adding chopped nuts, mini marshmallows, or dried fruit can also give the slice a different texture and taste.

Storage/Reheating

Store the slice in an airtight container in the refrigerator for up to 5 days. This slice is best enjoyed chilled and does not require reheating. For longer storage, the base can be frozen without the topping for up to 2 months, then thawed and topped with fresh chocolate.

FAQs

Can I make this slice ahead of time?

Yes, this slice is perfect for making a day or two in advance as it sets well and keeps its texture when chilled.

Do the Maltesers stay crunchy?

Some Maltesers soften slightly, but many keep their crunch, especially those near the top of the slice.

Can I freeze this slice?

Yes, it freezes best without the chocolate topping. Wrap it well to prevent freezer burn.

What biscuits work best in this recipe?

Plain sweet biscuits such as vanilla or tea-style biscuits work best for a balanced flavour.

Can I use only milk or only dark chocolate?

Yes, you can use either depending on how sweet or rich you want the slice to be.

Why do I need to let the mixture cool before adding Maltesers?

Cooling prevents the chocolate coating on the Maltesers from melting completely into the mixture.

Can I make this recipe gluten-free?

Yes, simply use gluten-free plain sweet biscuits.

How do I get clean slices?

Use a sharp knife warmed under hot water, wiping it clean between cuts.

Is the vegetable oil necessary in the topping?

The oil helps prevent the chocolate topping from cracking when sliced.

Can I reduce the sweetness?

You can reduce sweetness by using dark chocolate and adding less condensed milk, though this may affect texture.
