Preheat the Oven: Set your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper, making sure the paper extends over the edges for easy lifting later.
Bake the Pretzels: Arrange the pretzel sticks in a single layer on the prepared baking sheet. Bake them in the oven for 5 minutes.
Prepare the Caramel: While the pretzels are baking, place the unwrapped caramel candies in a microwave-safe bowl. Add the heavy cream to the bowl. Microwave in 30-second intervals, stirring well between each interval, until the mixture is smooth and fully melted.
Apply the Caramel: Once the pretzels are done baking, carefully remove them from the oven. Immediately pour the melted caramel over the pretzels, using a spatula or the back of a spoon to spread it evenly across the surface.
Melt the Chocolate: In a separate microwave-safe bowl, place the semisweet chocolate chips. Heat them in the microwave just like the caramel—30 seconds at a time—stirring after each interval until the chocolate is completely melted and smooth.
Add the Chocolate Drizzle: Gently drizzle the melted chocolate over the layer of caramel-covered pretzels. If desired, use a spatula to spread it out evenly.
Incorporate Nuts (Optional): If you’re adding chopped nuts, sprinkle them over the warm chocolate layer now. Press them down gently to ensure they stick to the chocolate.
Sprinkle with Sea Salt: Finish by lightly sprinkling a pinch of sea salt over the entire surface.
Allow to Set: Let the pretzel bark cool at room temperature until it solidifies. If you’re in a hurry, place the baking sheet in the refrigerator for about 30 minutes to hasten the setting process.
Break into Pieces: Once the bark is set, carefully lift it from the baking sheet using the edges of the parchment paper. Break it into pieces of your desired size.
