Break both the chocolates into chunks then melt in separate bowls either in the microwave or over a bain-marie (a bowl set over a saucepan of barely simmering water). Stir occasionally until all the chocolate is melted
Line a 9 x 9 tray with a piece of greaseproof then pour in the melted dark chocolate, smoothing out to the edges
Using a teaspoon, drizzle/flick the melted white chocolate over the dark chocolate. You can leave it as is or drag a knife or toothpick to 'feather' the two chocolates together
Evenly sprinkle over the remaining ingredients then put in the fridge for 10-15 minutes until the chocolate is set
Use a large sharp knife to cut diagonally across at angles
Can be kept in the fridge or at room temperature
