Prepare a baking sheet with parchment paper; set aside
Melt the chocolate in a microwave safe bowl in 30 second increments, stirring each time
Once the chocolate is 90% melted, remove the bowl from the microwave and continue stirring until all the chocolate is completely melted
While the chocolate is melting, place the caramel candies and heavy cream in a small saucepan; turn the heat on medium and stir until caramel is melted and the heavy cream is incorporated
Spread the melted chocolate on the prepared baking sheet
Using a spatula, evenly spread the chocolate to cover the parchment paper (approx ¼” thick)
While the chocolate is melted, swirl in the caramel sauce throughout
Sprinkle the chocolate pretzels and chopped peanuts over the chocolate and caramel
Allow the chocolate to cool at room temperature for 1-2 hours or for quicker dry time, place the chocolate bark in the refrigerator to harden
Once the chocolate is set, cut or break the chocolate bark into a desired size and shape
Serve immediately or store in an airtight container in the refrigerator
