This cake is the perfect family treat, and a real crowd-pleaser. The malt extract gives a lovely creaminess to the sponge, while the malted chocolate flavour is echoed in the cake’s topping.
1 You will need two 20cm (8in) round sandwich tins. Preheat the oven to 180°C/160°C fan/Gas 4 and grease the tins with butter and line the bases with baking paper.
2 Measure the malted chocolate drink powder and cocoa powder into a large bowl, pour over 2 tablespoons of water and mix to a paste. Add the remaining cake ingredients and beat until smooth.
3 Divide evenly between the prepared tins and bake in the oven for 20–25 minutes. Set aside in the tins to cool for 5 minutes, then turn out on to a wire rack to cool completely.
4 To make the icing, measure the malted chocolate drink powder into a bowl, add the hot milk and mix until smooth. Add the butter, icing sugar and melted chocolate and mix again until smooth, then add the boiling water to give a gloss to the icing.
5 Place one cake on a plate and spread over half the icing. Sandwich with the other cake and spread (or pipe) the remaining icing on top, using the tip of a rounded palette knife to create a swirled effect from the centre to the edge of the cake. Arrange the Maltesers over the top and dust with icing sugar before serving.
