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.

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

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?
