Place a sheet of grease proof paper on a baking tray and leave to one side.
Place the white chocolate in a large heat proof bowl and microwave in 20 second increments, stirring in between each increment, until melted. Alternatively, you can place the bowl over a simmering sauce pan of water and stir until melted.
Place the milk chocolate into a small heat proof bowl and repeat the steps above to melt.
Once all the chocolate is melted, pour the white chocolate onto your lined baking tray and spread into an even layer with a small spatula. Mine was around 2cm thick.
Spoon the milk chocolate randomly over the white chocolate, if there are blobs and then bits which are drizzled it's fine, the more random the better!
Take a skewer and swirl the chocolate together, I went up and down and then across, don't swirl too much otherwise it will become a mess; you still want to see lines of where the milk and white chocolate swirl together.
Chop up the Kinder Chocolate Bars and sprinkle over the melted chocolate.
Place in the fridge for 3 hours, break or slice into 10-12 pieces and enjoy.
Kinder Chocolate Bar Bark will keep in an airtight container at room temperature for 4 days.
