Microwave chocolate for 30 second increments, stirring well between each session until mostly melted, then stir until chocolate is melted completely.
Spread chocolate onto prepared sheet until about ¼” thick.
Combine the heavy cream and caramel together and microwave for 30 second increments, making sure to stir in between until caramel is smooth and creamy. It may look like there is too much liquid, but it does come together after mixing.
Spread caramel over the chocolate.
Sprinkle the chopped pecans and salt on top of the caramel.
Allow to set for about 30 minutes. You may want to chill the bark in the fridge or freezer to allow the caramel to set before breaking into pieces.
Notes
Store in an airtight container at room temperature, or place in the fridge or freezer.
