Step 1 – Make the crunchy crust
Preheat oven to 350°F (175°C). Line a 9×9-inch metal baking pan with a parchment paper “sling” (leave overhang on two opposite sides for easy lifting).
In a medium bowl, mix the crushed pretzels, melted butter, and granulated sugar until the texture resembles wet sand. Press the mixture firmly and evenly into the bottom of the prepared pan.
Bake for 10 minutes, then set aside to cool slightly.
Step 2 – Prepare the caramel layer
In a medium heavy-bottomed saucepan, combine the brown sugar, ½ cup butter, and heavy cream. Cook over medium heat, stirring constantly, until the butter is melted and the mixture comes to a boil.
Once boiling, stop stirring and let it boil for exactly 4 to 5 minutes, until the caramel reaches the “soft-ball” stage (235–240°F / 113–116°C on a candy thermometer).
Remove from heat and stir in the vanilla extract. Pour the caramel over the cooled pretzel crust, spreading evenly. Refrigerate for 30 minutes, until firm.
Step 3 – Add the chocolate crown
Melt the semi-sweet chocolate chips in the microwave in 30-second intervals, stirring between each, until smooth. Pour the melted chocolate over the chilled caramel layer and spread gently with an offset spatula.
Optional professional finish: Melt the white chocolate chips the same way, then drizzle in zig-zags over the dark chocolate while it’s still wet. Immediately sprinkle flaky sea salt over the top so it bonds to the chocolate before it sets.
Step 4 – Slice with precision
Chill the bars for at least 60 minutes, until the chocolate is completely firm. Use the parchment sling to lift the entire slab out of the pan.
Clean-cut secret: Run a sharp knife under hot water, wipe it dry, then slice. Repeat this before every single cut – this ensures the chocolate snaps cleanly without dragging through the sticky caramel. Cut into 16 squares.
Storage
Store bars in an airtight container in the refrigerator for up to 1 week. Bring to room temperature for 10 minutes before serving for the best texture.
