Prepare your baking sheet with parchment paper and set aside.
Create a double boiler by filling a saucepan with about 2-3 inches of water, and bring to a boil.
Then, place glass bowl on top of the sauce pan, making sure the bottom of the bowl doesn’t actually touch the water. Add your dark chocolate chips to the glass bowl.
Stir the chocolate chips as they slowly melt. You want texture to be smooth and pourable. Pour the melted chocolate onto your baking sheet, and spread evenly until you have a layer about 1/4" thick.
Sprinkle the chopped pistachios, cranberries, and coarse sea salt evenly over the chocolate.
Place the entire baking sheet into the freezer for about 25-30 minutes, to allow the chocolate to completely freeze.
Remove from the freezer and break the chocolate into uneven pieces, and enjoy.
Store in the freezer up to one month.
** You can substitute dark chocolate for white chocolate for another fun and festive treat!
