Double Choc Vanilla Slice
Prep: 15 Minutes - Cook: 30 Minutes - Easy - Serves 16
Proudly supported by

TIP! The cake pan we used is available at Woolworths supermarkets. To avoid condensation, cover slice in fridge once it is cold.  Use a small, serrated knife to cut through ganache and biscuits. 

Ingredients

1 ½ x 200g packets lattice biscuits

½ cup vanilla-flavoured custard powder

¼ cup cocoa powder, sifted

½ cup caster sugar

1 litre (4 cups) milk

300ml tub thickened cream

100g dark chocolate, finely chopped

2 teaspoons vanilla extract

5 teaspoons powdered gelatine

CHOCOLATE GANACHE

200g dark chocolate, finely chopped

1/3 cup thickened cream

Method

  1. Grease a 24cm square cake pan (base measures 20.5cm, with slopping sides). Line base and sides with baking paper, extending paper 3cm above pan edges.

  2. Arrange 13 of the biscuits, glazed-side down and trimming to fit, over base of pan. 

  3. Combine custard powder, cocoa and sugar in a large saucepan. Gradually whisk in ½ cup of the milk until smooth. Add remaining milk and cream. Whisk, over a high heat for about 8 to 9 minutes, or until mixture boils and thickens. Continue whisking for a further 2 minutes. 

  4. Remove pan from heat. Add chocolate and vanilla, stir until melted and smooth.

  5. Sprinkle gelatine over 1/3 cup water in a small heatproof jug. Sit jug in a saucepan of simmering water. Stir until gelatine is dissolved. Whisk into hot chocolate custard. 

  6. Pour over biscuits in pan. Place 16 of the biscuits, glazed-side up over top, reserving remaining for another use. Refrigerate overnight.

  7. To make chocolate ganache, combine chocolate and cream in a microwave-safe bowl. Microwave on High (100%) in 20 second bursts, stirring until smooth. Pour over slice. Spread evenly. Refrigerate until set.

  8. To serve, lift slice from pan. Using a hot knife, cut into squares.
