Marvellous Creations Chocolate Bars

I love chocolate.  And candy.  Anything with sugar as the number one ingredient is probably my favourite.  So combine the two and I'm basically in heaven.  I recently was shown the Dairy Milk Marvellous Creations chocolate bars and decided they were something I definitely needed to have in my life more often.  So rather than buy a bunch of bars, I decided to make them!  They were super easy to make and were just as good, if not better.  These are completely customizable and the possibilities are endless.

Ingredients:
Chocolate (I used some big hunks of milk chocolate from the bulk section)
Fillers: for this batch I used chopped up gummy bears, mini m&ms, and pop rocks

Method:
1. Melt down the chocolate using a double boiler
2. Add in your fillings
3. Line a cookie sheet with parchment paper, pour the chocolate/candy mixture onto the sheet, and refrigerate until the chocolate solidifies.  

What sort of things would you put in yours?
