These cookies feature rich, nutty flavors from brown butter, a perfect balance of sweet and salty with fleur de sel, and a subtle depth from espresso extract. They have soft centers and crispy edges, making them an addictive homemade treat.
Watch the butter closely while browning to avoid burning. Don’t skip the fleur de sel for the perfect salty crunch. Chill dough for 30 minutes if possible to help cookies hold shape and deepen flavor. Use room temperature eggs for even mixing. Do not overbake; cookies should look slightly underdone in the center when removed from oven. Espresso extract can be substituted with 1 tsp instant espresso powder in dry ingredients or 1 tbsp strong brewed espresso in wet ingredients. Rotate baking sheet halfway through baking for even browning.
