Line a tray with parchment paper and leave to the side
Prep what sweets/chocolate's are going on your bark. I crushed my smarties & malteser's - be careful when you do this bit!
Melt both types of chocolate - I melted my milk chocolate in a glass bowl over a pan of boiling water as there was more of it and then my white chocolate in the microwave on short bursts
Pour the milk chocolate into the tray and spread so its even and about 1cm thick
Drizzle the white chocolate over the top and using the end of a cake tester (or whatever you want) swirl the two types of chocolate together to make a marble pattern
Sprinkle over your decorations and leave to set. If its hot it might be best to do this in the fridge so it'll actually become hard
Cut/break into shards and enjoy!
Notes
This lovely little treat will last for weeks if kept in the right conditions - mine never lasts this long but I give it a 1 month date from making depending on what you use as chocolate use-by-dates are so long!
You can obviously use whatever sweets & chocolates that you fancy, but these are my personal favourites!
