These seemingly small cakes can easily be shared between two, depending on your tolerance for richness. That said, diehard chocoholics will have no trouble devouring the lot. Choose your audience – and portioning – accordingly.
Ingredients
Fudge sauce
Method
1.Preheat oven to 180°C, and butter and flour eight 10cm-diameter cake tins.
2.Melt butter and dark chocolate in a bowl over a saucepan of simmering water, stirring occasionally, until smooth (2-3 minutes). Remove from heat, add sugar, then mix in eggs one at a time, beating well between each addition. Sift flour, cocoa and baking powder over mixture, add a pinch of salt and stir until just combined (don’t overwork the mixture or the brownie will be cakey). Stir in milk chocolate and pistachio nuts, reserving a little of each to scatter on top.
3.Divide among prepared tins, smooth tops, scatter with reserved milk chocolate and slivers of pistachio nuts. Scatter with a little sea salt and bake until set around the edges but still a little fudgy in the centre (20-25 minutes; a skewer inserted should withdraw with just a little mixture on it). Cool in tins.
4.For fudge sauce, stir sugar, chocolate, glucose, cocoa, butter, 1 tsp sea salt and 150ml water in a saucepan over medium-high heat until smooth, bring to a simmer and cook until sauce has a light syrup consistency (3-4 minutes). Cool briefly.
5.To serve, top cakes with ice-cream, drizzle with warm fudge sauce and sprinkle with finely chopped pistachio nuts.
