Begin by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper, making sure it also covers the sides.
Spread the broken pretzel pieces evenly across the baking sheet, making sure they form a single layer.
Bake the pretzels in the preheated oven for about 5-7 minutes. Watch closely as they toast; you're looking for a slight golden color to develop without burning.
Meanwhile, in a microwave-safe bowl, combine both semi-sweet and dark chocolate chips. Microwave them in 30-second intervals, stirring in between each interval, until the chocolate is completely melted and smooth.
Once melted, pour the chocolate over the toasted pretzels. Use a spatula to spread the chocolate evenly across the surface.
Drizzle the caramel sauce generously over the layer of chocolate-covered pretzels, ensuring every area gets a touch.
Sprinkle the sea salt evenly over the top to enhance the sweet and salty flavor combination. If you’re using nuts, sprinkle them on at this point.
Carefully place the baking sheet in the refrigerator and allow it to chill for at least 1 hour or until the chocolate and caramel are solidified.
Once set, remove the baking sheet from the refrigerator. Break the bark into pieces of your preferred size and store them in an airtight container.
Notes
Arrange the bark in a decorative bowl or platter and consider garnishing with an extra sprinkle of sea salt or a drizzle of caramel on top before serving for a stunning visual effect.
