Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Spread the pretzel twists evenly on the baking sheet in a single layer.
Bake the pretzels for about 5 minutes to make them slightly crispy. Remove from the oven and let cool for a few minutes.
In a medium microwavable bowl, combine the caramel candies and heavy cream. Microwave in 30-second intervals, stirring in between, until melted and smooth. This should take about 1-2 minutes.
Pour the melted caramel over the pretzels, spreading it evenly to cover all of them.
In the same microwave, melt the semi-sweet chocolate chips in 30-second intervals, stirring until fully melted and smooth.
Drizzle the melted chocolate over the caramel-covered pretzels, using a spatula to spread it evenly if needed.
Sprinkle the sea salt over the top, followed by chopped pecans, mini chocolate chips, or sprinkles if using.
Let the bark cool at room temperature for at least 30 minutes until the chocolate hardens. For quicker results, place it in the refrigerator for about 15 minutes.
