Brown butter chocolate chip sourdough cookies with flaky sea salt offer a warm, nutty aroma from the browned butter, paired with a subtle tang from the sourdough starter that brightens the sweetness. The dough spreads into slightly crinkled edges that caramelize into crisp rims, while the centers stay soft and chewy with pockets of molten chocolate. A final kiss of flaky sea salt punctuates each bite, intensifying the chocolate and caramel notes. The result is a balanced, bakery-style cookie that feels both familiar and intriguingly complex. Serve warm with milk or vanilla ice cream for an indulgent treat.
