Prep and make the brownie batter
- Preheat oven to 350F, then line a 9x13 pan with parchment so it lifts out easily after baking.
- Melt unsalted butter and dark chocolate, then cool until warm-not-hot.
- Whisk in sugar, eggs, and vanilla until smooth and glossy.
- Fold in flour, cocoa, and salt just until no dry streaks remain.
Assemble and bake
- Spread the batter into the lined pan, keeping the top level for even caramel swirls.
- Drizzle thick caramel sauce over the batter and swirl with a knife for marbled ribbons.
- Press toasted pecan halves across the surface so they adhere to the batter as it bakes.
- Bake 28-32 minutes at 350F until the center is set with moist crumbs when gently pressed.
Finish
- Cool completely before slicing to keep the caramel from running.
- Melt semi-sweet chocolate chips for the drizzle, then drizzle over the cooled brownies.
- Sprinkle flaky sea salt over the top for a crisp, salty finish.
Notes
For clean slices, cool the brownies fully (room temperature, then chilled if you want extra firmness). Store covered in the refrigerator up to 5 days; freeze in an airtight container up to 2 months. For a lighter option, swap half the sugar for brown sugar plus a sugar substitute that measures like sugar, keeping the caramel topping and chocolate chips the same.
