These delicious malted millionaire’s shortbread slices have a buttery biscuit base instead of the traditional shortbread, making them quick and easy to whip up. The layered treats are filled with gooey malted caramel and topped with marbled chocolate. You can ﬁnd malt extract in health-food shops or online, great for making a tasty, retro malt loaf. To make them, you will need:
For the base:
250g malted milk biscuits or digestive biscuits
100g butter, plus extra for greasing
For the caramel:
100g soft light brown sugar
1 x 397g tin condensed milk
50g golden syrup 1 tbsp malt extract (optional)
For the topping:
200g dark chocolate, chopped
50g white chocolate, chopped
25g Maltesers, halved (optional)
You will also need a 20 x 30cm baking tin.
Grease the tin and line it with baking parchment. Blitz the biscuits with the Maltesers in a food processor until they resemble ﬁne breadcrumbs. Transfer the crumbs to a bowl. Melt the butter in a saucepan or in the microwave, then pour it into the crumbs and stir so the ingredients are really well combined.
Tip the buttered crumbs into the prepared tin and use a spatula to ﬁrmly press them down into an even layer. Pop the tin into the fridge or freezer to chill while you make the caramel.
Place the light brown sugar, butter, condensed milk, golden syrup and malt extract (if using) in a large saucepan and heat gently, stirring until the butter has melted. Turn the heat up and allow to simmer for 10–12 minutes, stirring all the time, until the mixture is thick and has a golden caramel colour.
Pour the hot caramel ﬁlling over the chilled base, leave it to cool for a couple of minutes and return it to the fridge or freezer for 10–15 minutes until it sets ﬁrm.
5When the caramel has set, melt the milk chocolate in a heatproof bowl set over a pan of simmering water or in the microwave. Melt the white chocolate in the same way. Pour the milk chocolate over the set base, then drizzle over the white chocolate and run a skewer or cocktail stick across the top to marble the chocolate.
Leave to set (you could decorate the top with maltesers if you want) then remove from the tin and cut into 24 slices.
The millionaire’s slices will keep, stored in an airtight container, for up to 1 week.
