Sea Salt Caramel Espresso Brownies

Rich, fudgy brownies infused with espresso and studded with swirled caramel. Bittersweet chocolate and dark brown sugar create depth, while a finishing sprinkle of flaked sea salt cuts through the sweetness. Baked until just set with a tender crumb, these are sophisticated enough for entertaining yet simple enough for weeknight indulgence.

Tips
Check brownies starting at 35 minutes as oven temperatures vary. A cake tester or toothpick inserted in the center should come out clean or with only a few crumbs for fudgy texture.
Allow chocolate mixture to cool for a minute after melting to prevent cooking eggs when added.
Good to Know
Cover and refrigerate up to 5 days. Freeze wrapped individually up to 3 months.
Prepare batter up to 2 hours ahead; refrigerate before baking.
Serve at room temperature or slightly warm with caramel and sea salt.
Common Mistakes
Overbake to avoid dense, dry brownies; start checking at 35 minutes.
Skip cooling the chocolate mixture to avoid scrambling eggs.
Overmix batter to avoid tough, cakey texture; fold gently until just combined.
